Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and General Information	THE HACKETT GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Basis of Presentation and General Information Nature of Business The Hackett Group is an intellectual property-based strategic consultancy and leading enterprise benchmarking and best practices implementation firm to global companies. Services include business transformation, enterprise performance management, working capital management, and global business services. The Hackett Group also provides dedicated expertise in business strategy, operations, finance, human capital management, strategic sourcing, procurement, and information technology, including its award-winning Oracle EPM and SAP practices. Basis of Presentation and Consolidation The accompanying consolidated financial statements include the Company’s accounts and those of its wholly-owned subsidiaries which the Company is required to consolidate. The Company consolidates the assets, liabilities, and results of operations of its entities. Fiscal Year The Company’s fiscal year generally consists of a 52-week period and periodically consists of a 53-week period as each fiscal year ends on the Friday closest to December 31. Fiscal years 2017, 2016, and 2015 ended on December 29, 2017, December 30, 2016, and January 1, 2016, respectively. References to a year included in the consolidated financial statements refer to a fiscal year rather than a calendar year. Cash and Restricted Cash The Company considers all short-term investments with maturities of three months or less to be cash equivalents to the extent that it places its temporary cash investments with high credit quality financial institutions. At times, such investments may be in excess of the F.D.I.C. insurance limits. As of December 29, 2017 and December 30, 2016, the Company did not have any restricted cash balances or cash equivalents. Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from its clients not making required payments. Management makes estimates of the collectability of accounts receivable and critically reviews accounts receivable and analyzes historical bad debts, past-due accounts, client credit-worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of the Company’s clients were to deteriorate, resulting in their inability to make payments, additional allowances may be required. Dividends In December 2012, the Company’s Board of Directors approved the initiation of an annual cash dividend program in the amount of $0.10 per share. The Company’s Board of Directors has been gradually increasing the dividend over the years. In fiscal 2016, the Company’s Board of Directors approved an increase in the annual dividend to $0.26 per share, to be paid semi-annually. In 2016, the Company paid dividends of $0.23 per share. In 2017, the Company’s Board of Directors approved an increase in the annual dividend to $0.30 per share. Subsequent to year end 2017, the Company’s Board of Directors approved the increase in the annual dividend from $0.30 per share to $0.34 per share to be paid on a semi-annual basis. The dividend policy is reviewed periodically by the Board of Directors. The amount and timing of all dividend payments is subject to the discretion of the Board of Directors and will depend upon business conditions, contractual obligations, legal restrictions, results of operations, financial conditions and other factors. Property and Equipment, Net Property and equipment are recorded at cost. Depreciation is calculated to amortize the depreciable assets over their useful lives using the straight-line method and commences when the asset is placed in service. The range of estimated useful lives is three to ten years. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for betterments and major improvements are capitalized. The carrying amount of assets sold or retired and related accumulated depreciation are removed from the balance sheet in the year of disposal and any resulting gains or losses are included in the consolidated statements of operations. 1. Basis of Presentation and General Information (continued) The Company capitalizes the costs of internal-use software, which generally includes hardware, software, and payroll-related costs for employees who are directly associated with, and who devote time, to the development of internal-use computer software. Long-Lived Assets (excluding Goodwill and Other Intangible Assets) Long-lived assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if there has been an impairment. The amount of an impairment is calculated as the difference between the fair value of the asset and its carrying value. Estimates of future undiscounted cash flows are based on management’s view of growth rates for the related business, anticipated future economic conditions and estimates of residual values. Business Combinations For transactions that are considered business combinations, the Company utilizes fair values in determining the carrying values of the purchased assets and assumed liabilities, which are recorded at fair value at acquisition date, and identifiable intangible assets are recorded at fair value. Costs directly related to the business combinations are recorded as expenses as they are incurred. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values become available. Goodwill and Other Intangible Assets Goodwill and intangible assets deemed to have indefinite lives are not amortized, but rather are tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment. Finite-lived intangible assets are amortized over their useful lives. The excess cost of the acquisition over the fair value of the net assets acquired is recorded as goodwill. Goodwill is tested at least annually for impairment at the reporting unit level utilizing the market approach. The reporting units consist of The Hackett Group (including Benchmarking, Business Transformation, Business Transformation Enterprise Performance Management (“EPM”), Strategy and Operations, Executive Advisory Programs and Robotics Process Automation) and Hackett Technology Solutions (including SAP ERP and SAP Application Maintenance and Support (“AMS”), Oracle EPM and EPM AMS). In assessing the recoverability of goodwill and intangible assets, the Company utilizes the market approach and makes estimates based on assumptions regarding various factors to determine if impairment tests are met. The market approach utilizes valuation multiples based on operating data from publicly traded companies within the same industry. Multiples derived from guideline companies provide an indication of how much a knowledgeable investor in the marketplace would be willing to pay for a company. These multiples are then applied to the Company’s reporting units to arrive at an indication of value. This approach contains management’s judgment, using appropriate and customary assumptions available at the time. The Company performed its annual step one impairment test of goodwill in the fourth quarter of fiscal years 2017 and 2016 and determined that goodwill was not impaired. The carrying amount and activity of goodwill attributable to The Hackett Group and Hackett Technology Solutions was as follows (in thousands): Hackett The Hackett Technology Group Solutions Total Balance at January 1, 2016 43,450 31,134 74,584 Foreign currency translation adjustment (2,208 ) — (2,208 ) Balance at December 30, 2016 41,242 31,134 72,376 Additions (see Note 15) 1,858 9,538 11,396 Foreign currency translation adjustment 1,302 — 1,302 Balance at December 29, 2017 $ 44,402 $ 40,672 $ 85,074 1. Basis of Presentation and General Information (continued) Other intangible assets are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset may not be fully recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if there has been an impairment. The amount of an impairment is calculated as the difference between the fair value of the asset and its carrying value. Estimates of future undiscounted cash flows are based on management’s view of growth rates for the related business, anticipated future economic conditions and estimates of residual values. Other intangible assets arise from business combinations and consist of customer relationships, customer backlog and trademarks that are amortized on a straight-line or accelerated basis over periods of up to ten years. Other intangible assets, included in other assets in the accompanying consolidated balance sheets, consist of the following (in thousands): December 29, December 30, 2017 2016 Gross carrying amount $ 27,147 $ 22,448 Accumulated amortization (21,869 ) (19,779 ) Foreign currency translation adjustment 245 33 $ 5,523 $ 2,702 All of the Company’s intangible assets are expected to be fully amortized by the end of 2027. For the years ended December 29, 2017, December 30, 2016 and January 1, 2016, the Company recorded $2.1 million, $1.1 million and $2.2 million of amortization expense, respectively. The estimated future amortization expense of intangible assets as of December 29, 2017 is as follows: $2.4 million in 2018, $0.7 million in 2019, $0.6 million in 2020, $0.6 million in 2021, $0.3 million in 2022 and $0.7 million thereafter. See Note 15 for further discussion. Revenue Recognition Revenue is principally derived from fees for services generated on a project-by-project basis . Revenue for time and materials contracts is recognized based on the number of hours worked by our consultants at an agreed upon rate per hour and is recognized in the period in which services are performed. Revenue related to fixed-fee or capped-fee contracts is recognized on the proportional performance method of accounting based on the ratio of labor hours incurred to estimated total labor hours. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted dollar amount used in this calculation excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed the original estimate. These increases can be as a result of an increase in project scope, unforeseen events that arise, or the inability of the client or the delivery team to fulfill their responsibilities. On an on-going basis, project delivery, Office of Risk Management and finance personnel review hours incurred and estimated total labor hours to complete projects. Any revisions in these estimates are reflected in the period in which they become known. If the Company estimates indicate that a contract loss will occur, a loss provision will be recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct costs of the contract exceed the estimated total revenue that will be generated by the contract and are included in total cost of service. Revenue from advisory services is recognized ratably over the life of the agreements. Additionally, the Company earns revenue from the resale of software licenses and maintenance contracts. Revenue for the resale software and software licenses is recognized upon contract execution and customer receipt of software. Revenue from maintenance contracts is recognized ratably over the life of the agreements. Revenue for contracts with multiple elements is allocated based on the respective selling price of the individual elements. Unbilled revenue represents revenue for services performed that have not been invoiced. If the Company does not accurately estimate the scope of the work to be performed, or does not manage its projects properly within the planned periods of time, or does not meet clients’ expectations under the contracts, then future consulting margins may be negatively affected or losses on existing contracts may need to be recognized. Any such reductions in margins or contract losses could be material to the Company’s results of operations. 1. Basis of Presentation and General Information (continued) Sales tax collected from customers and remitted to the applicable taxing authorities is accounted for on a net basis, with no impact on revenue. Revenue before reimbursements excludes reimbursable expenses charged to clients. Reimbursements, which include travel and out-of-pocket expenses, are included in revenue, and an equivalent amount of reimbursable expenses is included in cost of service. The agreements entered into in connection with a project, whether time and materials based or fixed-fee or capped-fee based, typically allow clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by the Company through the effective date of the termination. In addition, from time to time the Company enters into agreements with its clients that limit its right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit the Company from performing a defined range of services which it might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team. Stock Based Compensation The Company recognizes compensation expense for awards of equity instruments to employees based on the grant-date fair value of those awards, with limited exceptions, over the requisite service period. Restructuring Reserves Restructuring reserves reflect judgments and estimates of the Company’s ultimate costs of severance, closure and consolidation of facilities and settlement of contractual obligations under its operating leases, including sublease rental rates, absorption period to sublease space and other related costs. The Company reassesses the reserve requirements to complete each individual plan under the restructuring programs at the end of each reporting period. If these estimates change in the future or actual results differ from the Company’s estimates, additional charges may be required. Income Taxes Deferred tax assets and liabilities are determined based on differences between the financial reporting carrying values and tax bases of assets and liabilities, and are measured by using enacted tax rates expected to apply to taxable income in the years in which those differences are expected to reverse. Deferred income taxes also reflect the impact of certain state operating loss and tax credit carryforwards. A valuation allowance is provided if the Company believes it is more likely than not that all or some portion of the deferred tax asset will not be realized. An increase or decrease in the valuation allowance, if any, that results from a change in circumstances, and which causes a change in the Company’s judgment about the realizability of the related deferred tax asset, is included in the tax provision. The Company utilized a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods and income tax disclosures. The Company reports penalties and tax-related interest expense as a component of income tax expense. Net Income per Common Share Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. With regard to common stock subject to vesting requirements and restricted stock units issued to employees, the calculation includes only the vested portion of such stock. The potential issuance of common shares upon the exercise, conversion or vesting of unvested restricted stock units, common stock subject to vesting, stock options and stock appreciation right units ("SARs"), as calculated under the treasury stock method, may be dilutive. Diluted net income per share is computed by dividing the net income by the weighted average number of common shares outstanding, and will increase by the assumed conversion of other potentially dilutive securities during the period. 1. Basis of Presentation and General Information (continued) The following table reconciles basic and diluted weighted average shares: Year Ended December 29, December 30, January 1, 2017 2016 2016 Basic weighted average common shares outstanding 28,852,251 29,082,253 29,620,361 Effect of dilutive securities: Unvested restricted stock units and common stock subject to vesting requirements issued to employees 1,002,380 1,413,893 1,617,820 Common stock issuable upon the exercise of stock options and SARs 2,341,501 2,319,245 729,447 Dilutive weighted average common shares outstanding 32,196,132 32,815,391 31,967,628 There were 0.8 million, 0.8 million and 0.5 million shares of underlying awards granted excluded from the above reconciliation for the years ended 2017, 2016, and 2015, respectively, as their inclusion would have had an anti-dilutive effect on diluted net income per share. Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, accounts receivable and unbilled revenue, accounts payable, accrued expenses and other liabilities and debt. As of December 29, 2017 and December 30, 2016, the carrying amount of each financial instrument, with the exception of debt, approximated the instrument’s fair value due to the short-term nature and maturity of these instruments. The Company uses significant other observable market data or assumptions (Level 2 inputs as defined in accounting guidance) that it believes market participants would use in pricing debt. The fair value of the debt approximated its carrying amount using Level 2 inputs, due to the short-term variable interest rates based on market rates utilizing the market approach. Concentration of Credit Risk The Company provides services primarily to Global 2000 companies and other sophisticated buyers of business consulting and information technology services. The Company performs ongoing credit evaluations of its major customers and maintains reserves for potential credit losses. In 2017, 2016, and 2015, no customer accounted for more than 5% of total revenue. Management’s Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Other Comprehensive Income The Company reports its comprehensive income in accordance with FASB ASC Topic 220, Comprehensive Income, 1. Basis of Presentation and General Information (continued) Segment Reporting The Company engages in business activities in one operating segment, which provides business and technology consulting services. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance on revenue recognition, which provides for a single, principles-based model for revenue recognition and replaces the existing revenue recognition guidance. The guidance is effective for annual and interim periods beginning on or after December 15, 2017 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. It permits the use of either a full retrospective or modified retrospective transition method. The Company has completed its assessment of the impact of adopting the requirements of Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“Topic 606”) In February 2016, the FASB issued guidance on leases which supersedes the current lease guidance. The core principle requires lessees to recognize the assets and liabilities that arise from nearly all leases on the balance sheet. Accounting applied by lessors will remain largely consistent with previous guidance. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact of this standard on its consolidated financial statements and related disclosures. In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. Under the new standard, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit on the statements of income. An excess income tax benefit arises when the tax deduction of a share-based award for income tax purposes exceeds the compensation cost recognized for financial reporting purposes and, a tax deficiency arises when the compensation cost exceeds the tax deduction. Under current GAAP, excess tax benefits are recognized as additional paid-in capital while tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or on the statements of income. Management adopted the guidance effective December 31, 2016. As a result of the adoption of this guidance, management made an accounting policy election to recognize the effect of forfeitures in compensation cost when they occur, which had an immaterial impact on results of operations and financial position and no impact on cash flows at adoption. In the first quarter of 2017, the Company recorded no income tax expense as a result of the adoption of the new guidance relating to the accounting on the vesting of share-based awards. Excluding the effect of the new guidance, the effective tax rate would have been 34% for certain federal, foreign and state taxes during the twelve months ended December 29, 2017. In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments. The guidance provides specific clarification on eight cash flow classification issues, including contingent consideration payments made after a business combination. The guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted and the guidance requires a retrospective transition. We do not expect the guidance to have a material impact on our consolidated financial statements. In January 2017, the FASB issued guidance which simplifies the accounting for goodwill impairment. The guidance removes step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The standard should be applied prospectively and will become effective for the Company for their annual goodwill impairment test in fiscal years beginning after December 15, 2021. Early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted this standard in January 2017, and there was no material impact to its consolidated financial statements and related disclosures upon adoption of this guidance. 1. Basis of Presentation and General Information (continued) In January 2017, the FASB issued guidance which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses which distinction determines whether goodwill is recorded or not. This amended guidance was effective for us on December 30, 2017, and the Company does not expect it to have a material impact on its consolidated operating results or financial condition. In May 2017, the FASB issued guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The guidance will become effective for the Company in fiscal years beginning after December 15, 2017, with early adoption permitted. The standard should be applied prospectively to an award modified on or after the adoption date. The Company does not expect it to Reclassifications Certain prior period amounts in the consolidated financial statements, and notes thereto, have been reclassified to conform to current period presentation. 1

Credit Facility	8. Credit Facility The Company entered into a credit agreement with Bank of America, N.A. ("Bank of America"), pursuant to which Bank of America agreed to lend the Company up to $20.0 million pursuant to a revolving line of credit (the “Revolver”) and up to $47.0 million pursuant to a term loan (“the Term Loan”, and together with the Revolver, the “Credit Facility”). As of the end of January 1, 2016, the Company had fully utilized and paid off its Term Loan. As of the end of 2017 and 2016, the Company had a $19.0 million and a $7.0 million outstanding balance on the Revolver, respectively. On May 9, 2016, the Company amended and restated the credit agreement with Bank of America to: • Provide for up to an additional $25.0 million of borrowing under the Revolver for a total borrowing capacity of $45.0 million; and to • Extend the maturity date on the Revolver to May 9, 2021, five years from the date of this amendment of the Credit Agreement. The obligations of Hackett under the Credit Facility are guaranteed by active existing and future material U.S. subsidiaries of Hackett (the “U.S. Subsidiaries”), and are secured by substantially all of the existing and future property and assets of Hackett and the U.S. Subsidiaries, a 100% pledge of the capital stock of the U.S. Subsidiaries, and a 66% pledge of the capital stock of Hackett’s direct foreign subsidiaries (subject to certain exceptions). The interest rates per annum applicable to loans under the Credit Facility will be, at the Company’s option, equal to either a base rate or a LIBOR base rate, plus an applicable margin percentage. The applicable margin percentage is based on the consolidated leverage ratio, as defined in the Credit Agreement. As of December 29, 2017, the applicable margin percentage was 1.50% per annum based on the consolidated leverage ratio, in the case of LIBOR rate advances, and 0.75% per annum, in the case of base rate advances. The interest rate as of December 29, 2017 was 2.96%. The Company is subject to certain covenants, including total consolidated leverage, fixed cost coverage, adjusted fixed cost coverage and liquidity requirements, each as set forth in the Credit Agreement, subject to certain exceptions. As of December 29, 2017, the Company was in compliance with all covenants. In connection with the Credit Facility, the Company incurred $0.2 million of debt issuance costs. These costs are amortized over the remaining life of the Credit Facility and are included in Other Assets in the accompanying consolidated balance sheet. 8. Credit Facility (continued) As of December 30, 2016, the Company had a debt balance of $7.0 million. During 2017, the Company borrowed $26.0 million on the Revolver and through the year ended December 29, 2017, the Company has paid down $14.0 million, leaving $19.0 million outstanding under the Revolver, excluding the debt issuance costs of $0.3 million as of December 29, 2017.

Income Tax Disclosure [Abstract]
Income Taxes	THE HACKETT GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 9. Income Taxes The Company files federal income tax returns, as well as multiple state, local and foreign jurisdiction tax returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution on any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most probable outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. The resolution of a matter would be recognized as an adjustment to the provision for income taxes and the effective tax rate in the period of resolution. The Company is no longer subject to examinations of its federal income tax returns by the Internal Revenue Service for years through 2013 and all significant state, local and foreign matters have been concluded for years through 2013. In the first quarter of 2017, the IRS commenced an examination of the Company’s U.S. income tax return for fiscal year 2014, which is still in progress. The components of income before income taxes are as follows (in thousands): Year Ended December 29, December 30, January 1, 2017 2016 2016 Domestic $ 22,038 $ 28,611 $ 16,249 Foreign 8,200 5,555 5,267 Income before income taxes $ 30,238 $ 34,166 $ 21,516 9.

Income Taxes (continued) The 2017 Tax Cuts and Jobs Act (the “2017 Tax Act”) was signed into law on December 22, 2017. The 2017 Tax Act made a significant number of changes to existing U.S. Internal Revenue Code, including a permanent reduction of the U.S. corporate income tax rate from 35% to 21% for tax years beginning after December 31, 2017, and it also provides for a one-time transition tax on certain unremitted foreign earnings (the “Transition Tax”). As a result, the Company recorded a provisional income tax benefit of $4.0 million related to the re-measurement of deferred tax assets and liabilities resulting from the reduction of the federal corporate tax rate. The Company has performed a preliminary analysis of its post-1986 earnings and profits of its foreign subsidiaries and has estimated an overall accumulated net deficit, therefore no amounts have been recorded relative to the Transition Tax. In accordance with Staff Accounting Bulletin (“SAB”) No. 118, the Company will finalize the deferred tax and Transition Tax calculations during the allowed measurement period in 2018. The SEC staff issued Staff Accounting Bulletin ("SAB") No. 118 in December. The SAB provides guidance on accounting for the tax effects of the 2017 Tax Act where uncertainty exists, it provides a measurement period that should not extend beyond one year from the 2017 Tax Act enactment date for companies to complete the related accounting under U.S. GAAP. In accordance with this guidance, the company has recorded provisional amounts for those specific income tax effects of the 2017 Tax Act for which a reasonable estimate could be determined. As of December 29, 2017, the Company had $1.9 million of U.S. state net operating loss carryforwards. Additionally, at December 29, 2017, the Company had $3.7 million of foreign net operating loss carryforwards, of which $0.5 million related to operations in France and $0.8 million related to operations in Australia. A significant amount of the foreign net operating losses may be carried forward indefinitely. The liability method of accounting for deferred income taxes requires a valuation allowance against deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. In determining the need for valuation allowances the Company considers evidence such as history of losses and general economic conditions. At December 29, 2017 and December 30, 2016, the Company had a valuation allowance of $1.0 million for both periods, to reduce deferred income tax assets primarily related to foreign and state net operating loss and tax credit carryforwards. The undistributed earnings in foreign subsidiaries at December 31, 2017 was approximately $4.9 million. The company has historically reinvested its foreign earnings abroad indefinitely, and as a result no U.S. federal or state deferred income taxes have been provided on these earnings. The 2017 Tax Act implements a territorial system, whereby certain foreign subsidiary earnings can be repatriated to the U.S with no federal tax. As a result, the company is still evaluating the impact of the 2017 Tax Act on its assertion to indefinitely reinvest the earnings from certain of its foreign jurisdictions and therefore continues to assert that such earnings will be indefinitely reinvested. Penalties and tax-related interest expense are reported as a component of income tax expense. For the years ended December 29, 2017 and December 30, 2016, the total amount of accrued income tax-related interest and penalties was $256 thousand and $ 228 thousand, respectively. The Company prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods and income tax disclosures. The following table sets forth the detail and activity of the ASC 740-10 liability during the years ended December 29, 2017 and December 30, 2016 (in thousands): Year Ended December 29, December 30, 2017 2016 Beginning balance $ 738 $ 712 Additions based on tax positions 28 26 Reduction for prior year tax deductions — — Ending balance $ 766 $ 738 9. Income Taxes (continued) As of December 29, 2017 and December 30, 2016, the ASC 740-10, “Accounting for Uncertainty in Income Taxes”, liability of $0.8 million and $0.7 million, respectively, was classified as a current liability and included in accrued expenses and other liabilities in the accompanying consolidated balance sheets. The Company does not believe there will be any material changes in its unrecognized tax positions over the next twelve months. The reversal of ASC 740-10 tax liabilities as of December 29, 2017 and December 30, 2016 would have a favorable impact on the effective tax rate in future period. 1

Stock Based Compensation Stock Plans Total share based compensation included in net income for the years ended December 29, 2017, December 30, 2016, and January 1, 2016 is as follows: Year Ended December 29, December 30, January 1, 2017 2016 2016 Restricted stock units $ 7,801 $ 7,550 $ 6,776 Stock options and stock appreciation rights — — 2,658 Common stock subject to vesting requirements 2,515 1,215 927 $ 10,316 $ 8,765 $ 10,361 The number of shares available for future issuance under the Company's stock plans as of December 29, 2017 were 2,229,558. The Company issues new shares as they are required to be delivered under the plan. Stock Options and SARs The Company has granted stock options to employees and directors of the Company at exercise prices equal to the market value of the stock at the date of grant. The options generally vest ratably over four years, based on continued employment, with a maximum term of ten years. Stock option activity under the Company’s stock option plans for the year ended December 29, 2017 is summarized as follows: Option Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding as of December 30, 2016 230,167 $ 4.00 Exercised (50,000 ) 4.00 Forfeited or expired — — Outstanding as of December 29, 2017 180,167 $ 4.00 4.22 $ 2,109,818 Exercisable at December 29, 2017 180,167 $ 4.00 4.22 $ 2,109,818 A summary of the Company’s stock option activity for the years ended December 30, 2016 and January 1, 2016 was as follows: December 30, 2016 January 1, 2016 Option Shares Weighted Average Exercise Price Option Shares Weighted Average Exercise Price Outstanding at beginning of year 230,167 $ 4.00 297,667 4.00 Exercised — — (67,500 ) 3.99 Forfeited or expired — — — — Outstanding at end of year 230,167 $ 4.00 230,167 $ 4.00 Exercisable at end of year 230,167 $ 4.00 90,167 $ 4.00 10. Stock Based Compensation (continued) The fair value of the SARs and stock options is estimated using the Black-Scholes option pricing valuation model. The determination of fair value is affected by the Company's stock price, expected stock price volatility, expected term of the award and the risk-free rate of interest. Other information pertaining to stock option activity during the years ended December 29, 2017, December 30, 2016, and January 1, 2016 was as follows (in thousands): Year Ended December 29, 2017 December 30, 2016 January 1, 2016 Total intrinsic value of stock options exercised $ 803 $ — $ 660 On February 8, 2012, the Compensation Committee approved the fiscal year 2012 through 2015 equity compensation target for the Chief Executive Officer and Chief Operating Officer. Under this target, a single performance-based option grant was made to the Company’s Chief Executive Officer and the Chief Operating Officer of 1,912,500 options and 1,004,063 options, respectively, totaling 2,916,563 options, each with an exercise price of $4.00 and a fair value of $1.31. One -half of the options vest upon the achievement of at least 50% growth of pro forma earnings per share and the remaining half vest upon the achievement of at least 50% pro forma EBITDA growth. Pro forma EBITDA is defined as pro forma earnings (which specifically excludes non-cash stock compensation expense, intangible asset amortization expense, acquisition-related charges and gains, restructuring charges and assumes a normalized long-term cash rate of 30%) before interest, taxes and depreciation. Each metric can be achieved at any time during the six -year term of the award based on a trailing twelve-month period measured quarterly. The grants will expire if neither target is achieved during the six-year term. The base year for the performance calculation is fiscal 2011 for both pro forma earnings per share and pro forma EBITDA performance targets. In March of 2013, the performance-based stock option grants were surrendered by the Company’s Chief Executive Officer and Chief Operating Officer and replaced with SARs, totaling 2,916,563, equal in number to the number of options granted to each of them in 2012. The terms and conditions and the specific performance targets that must be achieved in order for the SAR s to vest are the same as those of the surrendered options, with the exception that the SARs will be settled in cash, stock or any combination thereof, at the Company’s discretion. The SARs related to the pro forma EPS target were earned and vested in the first quarter of 2015 with the Audit Committee’s approval of the Company’s 2014 financial statements and the SARs related to the pro forma EBITDA target were earned and vested in the first quarter of 2016 with the Audit Committee’s approval of the Company’s 2015 financial statements. As of December 29, 2017, no SARs had been exercised. SAR activity for the year ended December 29, 2017 was as follows: Number of SARs Weighted Average Exercise Price Weighted Average Fair Value Outstanding as of December 30, 2016 2,916,563 $ 4.00 1.31 Expired — — — Outstanding as of December 29, 2017 2,916,563 $ 4.00 $ 1.31 Exercisable at December 29, 2017 2,916,563 $ 4.00 $ 1.31 The following assumptions were used to determine the fair value of the SARs granted to employees: Expected volatility 43 % Risk-free rate 0.35% -1.00% Expected term (in years) 2-6 10. Stock Based Compensation (continued) As of December 29, 2017, 100% of total outstanding options and SARs were performance-based.

As of January 1, 2016, all stock compensation expense related to the outstanding options and SARs had been expensed. Restricted Stock Units Under the stock plans, participants may be granted restricted stock units, each of which represents a conditional right to receive a common share in the future. The restricted stock units granted under this plan generally vest over one of the following vesting schedules: (1) a four -year period, with 50% vesting on the second anniversary and 25% of the shares vesting on the third and fourth anniversaries of the grant date, (2) a four -year period, with 25% vesting on the first, second, third and fourth anniversary, or (3) a three -year period with 33% vesting on the first, second and third anniversary. Upon vesting, the restricted stock units will convert into an equivalent number of shares of common stock. The amount of expense relating to the restricted stock units is based on the closing market price of the Company’s common stock on the date of grant and is amortized on a straight-line basis over the applicable requisite service period. Restricted stock unit activity for the year ended December 29, 2017, was as follows: Number of Restricted Stock Units Weighted Average Grant-Date Fair Value Nonvested balance as of December 30, 2016 1,779,480 $ 9.02 Granted 674,592 16.60 Vested (862,731 ) 7.77 Forfeited (71,703 ) 13.24 Nonvested balance as of December 29, 2017 1,519,638 $ 12.96 The Company recorded restricted stock units based compensation expense of $7.8 million, $7.6 million and $6.8 million in 2017, 2016, and 2015, respectively, which is included in stock compensation expense, based on the vesting provisions of the restricted stock units and the fair market value of the stock on the grant date.

See Note 5 for further details. Common Stock Subject to Vesting Requirements Shares of common stock subject to vesting requirements were issued to employees of acquired companies.

Shareholders' Equity

Shareholders' Equity	12 Months Ended

Stockholders Equity Note [Abstract]
Shareholders' Equity	11. Shareholders’ Equity Employee Stock Purchase Plan Effective July 1, 1998, the Company adopted an Employee Stock Purchase Plan to provide substantially all employees who have completed three months of service as of the beginning of an offering period an opportunity to purchase shares of its common stock through payroll deductions. Purchases on any one grant are limited to 10% of eligible compensation. Shares of the Company’s common stock may be purchased by employees at six -month intervals at 95% of the fair market value on the last trading day of each six-month period. The aggregate fair market value, determined as of the first trading date of the offering period, of shares purchased by an employee may not exceed $25,000 annually. In 2017, subject to shareholder approval, the Company’s Board of Directors agreed to extend the Employee Stock Purchase Plan to July 1, 2023 from July 1, 2018 and added an additional 250,000 shares of common stock which increased the total available shares of common stock to 279,606. As of 2017, a total of 211,845 shares of common stock were available for purchase under the plan. For plan years 2017, 2016 and 2015 67,761 shares, 67,111 shares and 48,356 shares, respectively, were issued for total proceeds of $1.0 million, $1.0 million, and $0.7 million, respectively. Treasury Stock On July 30, 2002, the Company announced that its Board of Directors approved the repurchase of up to $5.0 million of the Company’s common stock. Since the inception of the repurchase plan, the Board of Directors approved the repurchase of an additional $132.2 million of the Company’s common stock, thereby increasing the total program size to $137.2 million as of December 29, 2017. As of December 29, 2017, the Company had effected cumulative purchases under the plan of $134.1 million, leaving $3.1 million available for future purchases. There is no expiration of the authorization. Under the repurchase plan, the Company may buy back shares of its outstanding stock from time to time either on the open market or through privately negotiated transactions, subject to market conditions and trading restrictions, excluding the above mentioned tender offers. During 2017 and 2016, the Company repurchased 748 thousand and 2.1 million shares of its common stock, respectively, at an average price per share of $15.11 and $14.60, respectively, for a total cost of $11.3 million and $30.1 million, respectively. As of December 29, 2017 and December 30, 2016, the Company had repurchased 26.9 million and 26.2 million shares of its common stock, respectively, at an average price of $4.97 and $4.69 per share, respectively. Subsequent to year end, the Company repurchased 53 thousand shares of the Company’s stock from members of its Board of Directors and Executive team for a total cost of $1.0 million, or $18.33 per share. The proceeds from the sale of these shares will be used in part to cover estimated tax liabilities associated with previously vested restricted stock units. This leaves $2.2 million available under the repurchase plan for future purchases. The Company holds repurchased shares of its common stock as treasury stock and accounts for treasury stock under the cost method. On May 6, 2016, the Company’s Board of Directors approved the repurchase of 697 thousand shares of its common stock from the Company’s CEO, 732 thousand shares of its common stock from the Company’s COO, and 73 thousand shares of its common stock from the Company’s CFO for a total of approximately 1.5 million shares at a purchase price of $14.77 per share. The transaction was approved by the Audit Committee of the Board of Directors which is comprised solely of independent directors and was effected as part of the Company’s share repurchase program. Following the transaction, Mr. Fernandez, Mr. Dungan and Mr. Ramirez remained the beneficial owners of 11.8%, 4.9% and 0.9% shares, respectively, of the outstanding common stock. One of the primary reasons for this transaction was to lower the Company’s weighted average shares outstanding which had increased by 11% from the first quarter of 2015 as a result of the vesting of the SARs and appreciation in share price. The repurchase reduced weighted average shares outstanding by approximately 4% and is $0.03 to $0.04 accretive on an annualized basis. Based on the most recent SEC filings, including shares of Company common stock beneficially owned and shares that could be acquired upon the exercise of the SARs, Mr. Fernandez continues to be the largest beneficial shareholder of the Company. Shares purchased under the repurchase plan do not include shares withheld to satisfy withholding tax obligations. These withheld shares are never issued and in lieu of issuing the shares, taxes were paid on the employee’s behalf. In 2017 and 2016, 268 thousand shares were withheld and not issued for a cost of $4.4 million and 294 thousand shares were withheld and not issued for a cost of $4.0 million, respectively, which are included under issuance of common stock in the accompanying consolidated statements of shareholders’ equity. Subsequent to December 29, 2017, 177 thousand shares have been withheld for a total cost of $ 3.1 million. 11. Shareholders’ Equity (continued) Dividends In December 2012, the Company announced an annual dividend program of $0.10 per share. In December 2012 and 2013, the Company paid annual dividends of $0.10 per share, or $3.1 million to shareholders of record as of close of business on December 20, 2012 and on December 10, 2013, respectively. In 2014, the Company increased the dividend to $0.12 per share, or $3.5 million, to shareholders of record as of close of business on December 10, 2014. In 2015, the Company increased the annual dividend to $0.20 per share to be paid on a semi-annual basis which resulted in aggregate dividends of $3.1 million and $3.2 million paid to shareholders of record on June 29, 2015 and December 28, 2015, respectively. In 2016, the Company increased the annual dividend to $0.26 per share to be paid on a semi-annual basis which resulted in aggregate dividends of $4.0 million and $4.0 million paid to shareholders of record on June 30, 2016 and December 22, 2016, respectively. In 2017, the Company increased the annual dividend to $0.30 per share to be paid on a semi-annual basis which resulted in aggregate dividends of $4.6 million and $4.7 million paid to shareholders of record on June 30, 2017 and December 22, 2017, respectively. These dividends were paid from U.S. domestic sources and are accounted for as an increase to retained deficit. The dividend declared in December 2017 was paid in January 2018. Subsequent to December 29, 2017, the Company increased its annual dividend to $0.34 per share to be paid on a semi-annual basis.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Business	Nature of Business The Hackett Group is an intellectual property-based strategic consultancy and leading enterprise benchmarking and best practices implementation firm to global companies. Services include business transformation, enterprise performance management, working capital management, and global business services. The Hackett Group also provides dedicated expertise in business strategy, operations, finance, human capital management, strategic sourcing, procurement, and information technology, including its award-winning Oracle EPM and SAP practices.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying consolidated financial statements include the Company’s accounts and those of its wholly-owned subsidiaries which the Company is required to consolidate. The Company consolidates the assets, liabilities, and results of operations of its entities.
Fiscal Year	Fiscal Year The Company’s fiscal year generally consists of a 52-week period and periodically consists of a 53-week period as each fiscal year ends on the Friday closest to December 31. Fiscal years 2017, 2016, and 2015 ended on December 29, 2017, December 30, 2016, and January 1, 2016, respectively. References to a year included in the consolidated financial statements refer to a fiscal year rather than a calendar year.
Cash and Restricted Cash	Cash and Restricted Cash The Company considers all short-term investments with maturities of three months or less to be cash equivalents to the extent that it places its temporary cash investments with high credit quality financial institutions. At times, such investments may be in excess of the F.D.I.C. insurance limits. As of December 29, 2017 and December 30, 2016, the Company did not have any restricted cash balances or cash equivalents.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from its clients not making required payments. Management makes estimates of the collectability of accounts receivable and critically reviews accounts receivable and analyzes historical bad debts, past-due accounts, client credit-worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of the Company’s clients were to deteriorate, resulting in their inability to make payments, additional allowances may be required.
Dividends	Dividends In December 2012, the Company’s Board of Directors approved the initiation of an annual cash dividend program in the amount of $0.10 per share. The Company’s Board of Directors has been gradually increasing the dividend over the years. In fiscal 2016, the Company’s Board of Directors approved an increase in the annual dividend to $0.26 per share, to be paid semi-annually. In 2016, the Company paid dividends of $0.23 per share. In 2017, the Company’s Board of Directors approved an increase in the annual dividend to $0.30 per share. Subsequent to year end 2017, the Company’s Board of Directors approved the increase in the annual dividend from $0.30 per share to $0.34 per share to be paid on a semi-annual basis. The dividend policy is reviewed periodically by the Board of Directors. The amount and timing of all dividend payments is subject to the discretion of the Board of Directors and will depend upon business conditions, contractual obligations, legal restrictions, results of operations, financial conditions and other factors.
Property and Equipment, Net	THE HACKETT GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Property and Equipment, Net Property and equipment are recorded at cost. Depreciation is calculated to amortize the depreciable assets over their useful lives using the straight-line method and commences when the asset is placed in service. The range of estimated useful lives is three to ten years. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for betterments and major improvements are capitalized. The carrying amount of assets sold or retired and related accumulated depreciation are removed from the balance sheet in the year of disposal and any resulting gains or losses are included in the consolidated statements of operations. 1. Basis of Presentation and General Information (continued) The Company capitalizes the costs of internal-use software, which generally includes hardware, software, and payroll-related costs for employees who are directly associated with, and who devote time, to the development of internal-use computer software. 1
Long-Lived Assets (excluding Goodwill and Other Intangible Assets)	Long-Lived Assets (excluding Goodwill and Other Intangible Assets) Long-lived assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if there has been an impairment. The amount of an impairment is calculated as the difference between the fair value of the asset and its carrying value. Estimates of future undiscounted cash flows are based on management’s view of growth rates for the related business, anticipated future economic conditions and estimates of residual values.
Business Combinations	Business Combinations For transactions that are considered business combinations, the Company utilizes fair values in determining the carrying values of the purchased assets and assumed liabilities, which are recorded at fair value at acquisition date, and identifiable intangible assets are recorded at fair value. Costs directly related to the business combinations are recorded as expenses as they are incurred. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values become available.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and intangible assets deemed to have indefinite lives are not amortized, but rather are tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment. Finite-lived intangible assets are amortized over their useful lives. The excess cost of the acquisition over the fair value of the net assets acquired is recorded as goodwill. Goodwill is tested at least annually for impairment at the reporting unit level utilizing the market approach. The reporting units consist of The Hackett Group (including Benchmarking, Business Transformation, Business Transformation Enterprise Performance Management (“EPM”), Strategy and Operations, Executive Advisory Programs and Robotics Process Automation) and Hackett Technology Solutions (including SAP ERP and SAP Application Maintenance and Support (“AMS”), Oracle EPM and EPM AMS). In assessing the recoverability of goodwill and intangible assets, the Company utilizes the market approach and makes estimates based on assumptions regarding various factors to determine if impairment tests are met. The market approach utilizes valuation multiples based on operating data from publicly traded companies within the same industry. Multiples derived from guideline companies provide an indication of how much a knowledgeable investor in the marketplace would be willing to pay for a company. These multiples are then applied to the Company’s reporting units to arrive at an indication of value. This approach contains management’s judgment, using appropriate and customary assumptions available at the time. The Company performed its annual step one impairment test of goodwill in the fourth quarter of fiscal years 2017 and 2016 and determined that goodwill was not impaired. The carrying amount and activity of goodwill attributable to The Hackett Group and Hackett Technology Solutions was as follows (in thousands): Hackett The Hackett Technology Group Solutions Total Balance at January 1, 2016 43,450 31,134 74,584 Foreign currency translation adjustment (2,208 ) — (2,208 ) Balance at December 30, 2016 41,242 31,134 72,376 Additions (see Note 15) 1,858 9,538 11,396 Foreign currency translation adjustment 1,302 — 1,302 Balance at December 29, 2017 $ 44,402 $ 40,672 $ 85,074 1. Basis of Presentation and General Information (continued) Other intangible assets are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset may not be fully recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if there has been an impairment. The amount of an impairment is calculated as the difference between the fair value of the asset and its carrying value. Estimates of future undiscounted cash flows are based on management’s view of growth rates for the related business, anticipated future economic conditions and estimates of residual values. Other intangible assets arise from business combinations and consist of customer relationships, customer backlog and trademarks that are amortized on a straight-line or accelerated basis over periods of up to ten years. Other intangible assets, included in other assets in the accompanying consolidated balance sheets, consist of the following (in thousands): December 29, December 30, 2017 2016 Gross carrying amount $ 27,147 $ 22,448 Accumulated amortization (21,869 ) (19,779 ) Foreign currency translation adjustment 245 33 $ 5,523 $ 2,702 All of the Company’s intangible assets are expected to be fully amortized by the end of 2027. For the years ended December 29, 2017, December 30, 2016 and January 1, 2016, the Company recorded $2.1 million, $1.1 million and $2.2 million of amortization expense, respectively. The estimated future amortization expense of intangible assets as of December 29, 2017 is as follows: $2.4 million in 2018, $0.7 million in 2019, $0.6 million in 2020, $0.6 million in 2021, $0.3 million in 2022 and $0.7 million thereafter. See Note 15 for further discussion.
Revenue Recognition	Revenue Recognition Revenue is principally derived from fees for services generated on a project-by-project basis . Revenue for time and materials contracts is recognized based on the number of hours worked by our consultants at an agreed upon rate per hour and is recognized in the period in which services are performed. Revenue related to fixed-fee or capped-fee contracts is recognized on the proportional performance method of accounting based on the ratio of labor hours incurred to estimated total labor hours. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted dollar amount used in this calculation excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed the original estimate. These increases can be as a result of an increase in project scope, unforeseen events that arise, or the inability of the client or the delivery team to fulfill their responsibilities. On an on-going basis, project delivery, Office of Risk Management and finance personnel review hours incurred and estimated total labor hours to complete projects. Any revisions in these estimates are reflected in the period in which they become known. If the Company estimates indicate that a contract loss will occur, a loss provision will be recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct costs of the contract exceed the estimated total revenue that will be generated by the contract and are included in total cost of service. Revenue from advisory services is recognized ratably over the life of the agreements. Additionally, the Company earns revenue from the resale of software licenses and maintenance contracts. Revenue for the resale software and software licenses is recognized upon contract execution and customer receipt of software. Revenue from maintenance contracts is recognized ratably over the life of the agreements. Revenue for contracts with multiple elements is allocated based on the respective selling price of the individual elements. Unbilled revenue represents revenue for services performed that have not been invoiced. If the Company does not accurately estimate the scope of the work to be performed, or does not manage its projects properly within the planned periods of time, or does not meet clients’ expectations under the contracts, then future consulting margins may be negatively affected or losses on existing contracts may need to be recognized. Any such reductions in margins or contract losses could be material to the Company’s results of operations. 1. Basis of Presentation and General Information (continued) Sales tax collected from customers and remitted to the applicable taxing authorities is accounted for on a net basis, with no impact on revenue. Revenue before reimbursements excludes reimbursable expenses charged to clients. Reimbursements, which include travel and out-of-pocket expenses, are included in revenue, and an equivalent amount of reimbursable expenses is included in cost of service. The agreements entered into in connection with a project, whether time and materials based or fixed-fee or capped-fee based, typically allow clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by the Company through the effective date of the termination. In addition, from time to time the Company enters into agreements with its clients that limit its right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit the Company from performing a defined range of services which it might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team.
Stock Based Compensation	Stock Based Compensation The Company recognizes compensation expense for awards of equity instruments to employees based on the grant-date fair value of those awards, with limited exceptions, over the requisite service period.
Restructuring Reserves	Restructuring Reserves Restructuring reserves reflect judgments and estimates of the Company’s ultimate costs of severance, closure and consolidation of facilities and settlement of contractual obligations under its operating leases, including sublease rental rates, absorption period to sublease space and other related costs. The Company reassesses the reserve requirements to complete each individual plan under the restructuring programs at the end of each reporting period. If these estimates change in the future or actual results differ from the Company’s estimates, additional charges may be required.
Income Taxes	Income Taxes Deferred tax assets and liabilities are determined based on differences between the financial reporting carrying values and tax bases of assets and liabilities, and are measured by using enacted tax rates expected to apply to taxable income in the years in which those differences are expected to reverse. Deferred income taxes also reflect the impact of certain state operating loss and tax credit carryforwards. A valuation allowance is provided if the Company believes it is more likely than not that all or some portion of the deferred tax asset will not be realized. An increase or decrease in the valuation allowance, if any, that results from a change in circumstances, and which causes a change in the Company’s judgment about the realizability of the related deferred tax asset, is included in the tax provision. The Company utilized a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods and income tax disclosures. The Company reports penalties and tax-related interest expense as a component of income tax expense.
Net Income per Common Share	Net Income per Common Share Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. With regard to common stock subject to vesting requirements and restricted stock units issued to employees, the calculation includes only the vested portion of such stock. The potential issuance of common shares upon the exercise, conversion or vesting of unvested restricted stock units, common stock subject to vesting, stock options and stock appreciation right units ("SARs"), as calculated under the treasury stock method, may be dilutive. Diluted net income per share is computed by dividing the net income by the weighted average number of common shares outstanding, and will increase by the assumed conversion of other potentially dilutive securities during the period. 1. Basis of Presentation and General Information (continued) The following table reconciles basic and diluted weighted average shares: Year Ended December 29, December 30, January 1, 2017 2016 2016 Basic weighted average common shares outstanding 28,852,251 29,082,253 29,620,361 Effect of dilutive securities: Unvested restricted stock units and common stock subject to vesting requirements issued to employees 1,002,380 1,413,893 1,617,820 Common stock issuable upon the exercise of stock options and SARs 2,341,501 2,319,245 729,447 Dilutive weighted average common shares outstanding 32,196,132 32,815,391 31,967,628 There were 0.8 million, 0.8 million and 0.5 million shares of underlying awards granted excluded from the above reconciliation for the years ended 2017, 2016, and 2015, respectively, as their inclusion would have had an anti-dilutive effect on diluted net income per share.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, accounts receivable and unbilled revenue, accounts payable, accrued expenses and other liabilities and debt. As of December 29, 2017 and December 30, 2016, the carrying amount of each financial instrument, with the exception of debt, approximated the instrument’s fair value due to the short-term nature and maturity of these instruments. The Company uses significant other observable market data or assumptions (Level 2 inputs as defined in accounting guidance) that it believes market participants would use in pricing debt. The fair value of the debt approximated its carrying amount using Level 2 inputs, due to the short-term variable interest rates based on market rates utilizing the market approach.
Concentration of Credit Risk	Concentration of Credit Risk The Company provides services primarily to Global 2000 companies and other sophisticated buyers of business consulting and information technology services. The Company performs ongoing credit evaluations of its major customers and maintains reserves for potential credit losses. In 2017, 2016, and 2015, no customer accounted for more than 5% of total revenue.
Management's Estimates	Management’s Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Other Comprehensive Income	Other Comprehensive Income The Company reports its comprehensive income in accordance with FASB ASC Topic 220, Comprehensive Income,
Segment Reporting	Segment Reporting The Company engages in business activities in one operating segment, which provides business and technology consulting services.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance on revenue recognition, which provides for a single, principles-based model for revenue recognition and replaces the existing revenue recognition guidance. The guidance is effective for annual and interim periods beginning on or after December 15, 2017 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. It permits the use of either a full retrospective or modified retrospective transition method. The Company has completed its assessment of the impact of adopting the requirements of Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“Topic 606”) In February 2016, the FASB issued guidance on leases which supersedes the current lease guidance. The core principle requires lessees to recognize the assets and liabilities that arise from nearly all leases on the balance sheet. Accounting applied by lessors will remain largely consistent with previous guidance. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact of this standard on its consolidated financial statements and related disclosures. In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. Under the new standard, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit on the statements of income. An excess income tax benefit arises when the tax deduction of a share-based award for income tax purposes exceeds the compensation cost recognized for financial reporting purposes and, a tax deficiency arises when the compensation cost exceeds the tax deduction. Under current GAAP, excess tax benefits are recognized as additional paid-in capital while tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or on the statements of income. Management adopted the guidance effective December 31, 2016. As a result of the adoption of this guidance, management made an accounting policy election to recognize the effect of forfeitures in compensation cost when they occur, which had an immaterial impact on results of operations and financial position and no impact on cash flows at adoption. In the first quarter of 2017, the Company recorded no income tax expense as a result of the adoption of the new guidance relating to the accounting on the vesting of share-based awards. Excluding the effect of the new guidance, the effective tax rate would have been 34% for certain federal, foreign and state taxes during the twelve months ended December 29, 2017. In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments. The guidance provides specific clarification on eight cash flow classification issues, including contingent consideration payments made after a business combination. The guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted and the guidance requires a retrospective transition. We do not expect the guidance to have a material impact on our consolidated financial statements. In January 2017, the FASB issued guidance which simplifies the accounting for goodwill impairment. The guidance removes step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The standard should be applied prospectively and will become effective for the Company for their annual goodwill impairment test in fiscal years beginning after December 15, 2021. Early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted this standard in January 2017, and there was no material impact to its consolidated financial statements and related disclosures upon adoption of this guidance. 1. Basis of Presentation and General Information (continued) In January 2017, the FASB issued guidance which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses which distinction determines whether goodwill is recorded or not. This amended guidance was effective for us on December 30, 2017, and the Company does not expect it to have a material impact on its consolidated operating results or financial condition. In May 2017, the FASB issued guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The guidance will become effective for the Company in fiscal years beginning after December 15, 2017, with early adoption permitted. The standard should be applied prospectively to an award modified on or after the adoption date. The Company does not expect it to
