Description Of Business And Basis Of Presentation [Abstract]
Description Of Business And Basis Of Presentation	1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Navigant Consulting, Inc. (“Navigant,” “we,” “us,” or “our”) (NYSE: NCI) is a specialized, global professional services firm that helps clients take control of their future. With a focus on markets and clients facing transformational change and significant regulatory or legal pressures, Navigant primarily serves clients in the healthcare, energy and financial services industries. The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim reporting and do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America (GAAP). The information contained herein includes all adjustments, consisting of normal and recurring adjustments except where indicated, which are, in the opinion of management, necessary for a fair presentation of the results of operations for the interim periods presented. The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the results to be expected for the enti re year ending December 31, 2017 . These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes as of and for the year ended December 31, 2016 included in our Annual Report on Form 10-K filed with the SEC on February 1 7, 2017 (201 6 Form 10-K). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and the related notes. Actual results could differ from those estimates and may affect future results of operations and cash flows. We have evaluated events and transactions occurring after the balance sheet date and prior to the date of the filing of this report.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2 . RECENT ACCOUNTING PRONOUNCEMENTS There have b een no material changes to our significant accounting policies and estimates from the informat ion provided in Part II, Item 8, “Financial Statements and Supplementary Data” in our 2016 Form 10-K. Recently Adopted Accounting Pronouncements On January 1, 2017, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. As required by the standard, excess tax benefits and deficiencies recognized on share-based compensation expense are recorde d in the consolidated statement of comprehensive income as a component of income tax expense. Previously, these amounts were recorded as a component of additional paid-in capital on the consolidated balance sheet . We elected to apply the change in presentatio n to the consolidated statement of cash flows prospectively to classify excess tax benefits as an operating activity rather than a financing activity. Upon adoption, we determined that we did not have previously unrecognized excess tax benefits to be recognized on a modified retrospective transition method as an adjustment to retained earnings. We will continue to classify cash pai d related to shares withheld to satisfy tax-withholding requirements as a financing activity, as required by the standard. We made a policy election to account for forfeitures as they occur, rather than estimating the expected forfeitures over the course of the vesting period. The cumulative-effect adjustment to retained earnings as of the date of adoption was $0.4 million, with a reduction in the related deferred tax liability of $0.3 million. ASU 2016-09 also requires that excess tax benefits and deficiencies be prospectively excluded from assumed future proceeds in the calculation of diluted weighted average shares when calculating diluted earnings per share utilizing the treasury stock method. We applied this change prospectively, and it did not have a material impact on our unaudited consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350), which simplifies the goodwill impairment test by eliminating step 2, which is the step requiring companies to perform a hypothetical purchase price allocation to measure goodwill. Instead, under the new standard, impairment will be measured using the difference between the fair value of a reporting unit with its carrying amount. Any impairment charge will be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, taking into consideration income tax effects from any deductible goodwill on the carrying amount of the reporting unit. This standard will be effective for public companies for annual and interim periods beginning after December 15, 2019 and will be applied prospectively. Early adoption is permitted on impairment tests performed on testing dates after January 1, 2017. The Company early adopted this standard during the first quarter of 2017; the adoption did not have a material effect on our unaudited consolidated financial statements or related disclosures. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This update is intended to improve the financial reporting requirements for revenue from contracts with customers by providing a principle-based approach. The core principle of the standard is that revenue should be recognized when the transfer of promised goods or services is made in an amount that the entity expects to be entitled to in exchange for the transfer of goods and services. The update also requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on principal versus agent considerations, accounting for licenses of intellectual property and identifying performance obligations. Although early adoption as of the original effective date of January 1, 2017 is permitted, we have elected to adopt the guidance effective January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate that the largest impact to us of adopting the guidance will occur with contracts which include variable consideration, and therefore, anticipate using the cumulative catch-up transition method of adoption. We will continue to evaluate the impact of our pending adoption of this guidance to our consolidated financial statements, but our preliminary assessments of the impact of our adoption of this guidance are subject to change. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update amends the requirements for assets and liabilities recognized for all leases longer than twelve months. Lessees will be required to recognize a lease liability measured on a discounted basis, which is the lessee’s obligation to make lease payments arising from the lease, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2018. Early adoption of the standard is permitted. The standard will require a modified retrospective approach for leases existing at or entered into after the beginning of the earliest comparative period presented. We are currently evaluating the potential impact of our adoption of this guidance on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flow (Topic 230). This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provides new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2017. Early adoption of the standard is permitted. The standard will be applied in a retrospective approach for each period presented. We have completed an initial evaluation of the impact of our adoption of this standard and have determined that the manner in which we classify our contingent acquisition liability payments in the consolidated statement of cash flows will change. Based on our initial evaluation, our adoption of this standard may require an immaterial reclassification of a portion of the payments previously reported as financing activities for comparative periods in the statement of cash flows within our consolidated financial statements issued on or after January 1, 2018. Under this guidance, portions of these payments will be reclassified from financing activities to operating activities. We will continue to evaluate the potential impact of our adoption of this guidance on our consolidated financial statements, but our preliminary assessments of the impact of our adoption of this guidance are subject to change. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (Topic 805), which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard will be effective for public companies for annual and interim periods beginning after December 15, 2017. Early adoption is permitted effective for transactions not yet reported in financial statements issued or made available for issuance. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.

We performed our annual goodwill impairment test as of May 31, 2016 . The key assumptions included: internal projections completed during our second quarter 2016 forecasting process; profit margin improvement generally consistent with our longer-term historical performance; assumptions regarding contingent revenue; revenue growth consistent with our longer term historical performance also considering our near term investment plans and growth objectives; discount rates that were determined based on comparable discount rates for our peer group; Company-specific risk considerations; control premium ; and cost of capital based on our historical experience . Based on our assumptions, at that time, the estimated fair value exceeded the net asset carrying value for each of our reporting units as of May 31, 201 6 . Accordingly, there was no indication of impairment of our goodwill for any of our reporting units. As of May 31, 2016, the estimated fair value of our Healthcare, Energy, Financial Services Advisory and Compliance, and Disputes, Forensics & Legal Technology reporting units exceeded the fair value of invested capital by 22% , 32% , 61% , and 17% , respectively . We have reviewed our most recent financial projections and considered the impact of changes to our business and market conditions on our goodwill valuation and determined that no events or conditions have occurred or are expected to occur that would trigger a need to perform an interim goodwill impairment test. We will continue to monitor the factors and key assumptions used in determining the fair value of each of our reporting units. There can be no assurance that goodwill or intangible assets will not be impaired in the future. We will perform our next annual goodwill impair ment test as of May 31, 2017 .

Services are generally billed on a monthly basis for the prior month’s services. Our allowance for uncollectible accounts is based on historical experience and management judgment and may change based on market conditions or specific client circumstances.

These loans were issued to recruit or r etain certain senior-level client-service employees . During the three months ended March 31, 2017, we issued an unsecured employee loan aggregating to $1.0 million , and during the three months ended March 31, 2016, no such loans were issued. The principal amount and accrued interest on these loans is either paid by the employee or forgiven by us over the term of the loans so long as the employee remains continuously employed by us and complies with certain contractual requirements. The expense associated with the forgiveness of the principal amount of the loans is amortized as compensation expense over the service period, which is consistent with the term of the loans. Capitalized client-facing software is used by our clients as part of client engagements. These amounts are amortized into cost of services before reimbursable expenses over their estimated remaining useful life. Prepaid recruiting and retention incentives, current and non-current, include sign-on and retention bonuses that are generally recoverable from an employee if the employee voluntarily terminates employment or if the employee’s employment is terminated for “cause” prior to fulfilling his or her obligations to us. These amounts are amortized as compensation expense over the period in which they are recoverable from the employee, generally in periods up to six years. During the three months ended March 31, 2017 and 2016, we granted $2.7 million and $6.5 million, respectively, in sign-on and retention bonuse s.

During the three months ended March 31, 2017 , we recorded a fair value adjustment which increased deferred contingent acquisition liabilities by $1.2 million. See Note 12 – Fair Value for additional information regarding deferred contingent consideration fair value adjustments. The current and non-current portion s of deferred rent relates to tenant allowances and incentives on lease arrangements for our office facilities that expire at various dates through 2028 . At March 31, 2017 , other non-current liabilities included $3.0 million of performance-based long-term incentive compensation liabilities. As part of our long-term incentive program for select senior-level client service employees and leaders, we grant restricted stock units which vest three years from the grant date . The value of equity granted is based on the achievement of certain performance targets during the year prior to grant . Deferred revenue represents advance billings to our clients for services that have not yet been performed and earned.

Derivatives And Hedging Activity [Abstract]
Derivatives And Hedging Activity	10 . DERIVATIVES AND HEDGING ACTIVITY During the three months ended March 31, 2017 , the interest rate derivatives outstanding were as follows (summarized based on month of execution):    Number of Total Notional Amount  Month executed Contracts Beginning Date Maturity Date Rate (millions)  July 2014 5 July 11, 2014 July 11, 2017 1.10% $30.0  March 2015 1 May 29, 2015 May 31, 2018 1.47% $10.0  June 2015 1 June 30, 2015 June 30, 2018 1.40% $5.0  We expect the interest rate derivatives to be highly effective against changes in cash flows related to changes in interest rates and have recorded the derivatives as a cash flow hedge. As a result, gains or losses related to fluctuations in the fair value of the interest rate derivatives are recorded as a component of accumulated other comprehensive loss and reclassified into interest expense as the variable interest expense on our bank debt is recorded. There was no ineffectiveness related to the interest rate derivatives during the three months ended March 31, 2017 . During the three months ended March 31, 2017 and 2016 , we recorded nil and $0.1 million, respectively, in interest expense associated with differentials received or paid under the interest rate derivatives. In connection with the refinancing of our credit facility (see Note 11 – Bank Debt), $15 million of our interest rate derivative contracts were terminated prior to maturity and replaced with $15 million in new contracts with a three -year maturity.

Bank Debt [Abstract]
Bank Debt	1 1 . BANK DEBT On March 28, 2017, we entered into a new credit agreement with a syndicate of banks, amending and extending the maturity date of the five -year $400 million revolving credit facility provided under our prior credit agreement. As amended and restated, the credit facility matures on March 28, 20 22 . At our option, subject to the terms and conditions specified in the credit agreement, we may elect to increase commitments under the credit facility up to an aggregate amount of $500 million. Borrowings and repayments under the credit facility may be made in multiple currencies including U nited States (U.S.) Dollars, Canadian Dollars, United Kingdom (U.K.) Pound Sterling and Euro. At March 31, 2017 , we had aggregate borrowings outstanding of $178.3 million, compared to $135 . 0 million at December 31, 2016 . Based on our financial covenants at March 31, 2017 , approximately $217.8 m illion in additional borrowings were available to us under the credit facility. At March 31, 2017 , we had $3.9 million of unused letters of credit under our credit facility, which have been included as a reduction in the available borrowings above. The letters of credit are primarily related to the requirements of certain lease agreements for office space. At our option, borrowings under the credit facility bear interest at a variable rate equal to an applicable base rate or LIBOR, in each case plus an applicable margin. For LIBOR loans, the applicable margin varies depending upon our consolidated leverage ratio (the ratio of total funded debt to adjusted EBITDA, as defined in the credit agreement). At March 31, 2017 , the applicable margins on LIBOR and base rate loans were 1.00 % and 0.00% , respectively. Depending upon our performance and financial condition, our LIBOR loans will have applicable margins varying between 1.00 % and 2.00 % , and our base rate loans have applicable margins varying between zero and 1.00 % . Our average borrowing rate (including the impact of our interest rate derivatives; see Note 10 — Derivatives and Hedging Activity) was 2.7% and 2.3% for the three months ended March 31, 2017 and 2016, respectiv ely . Our credit agreement contains certain financial covenants, including covenants that require that we maintain a consolidated leverage ratio of not greater than 3.5 :1 , with certain exceptions as defined in the agreement and a consolidated interest coverage ratio (the rat io of the sum of adjusted EBIT, as defined in the credit agreement , to cash interest expense) of not less than 2.0 :1. At March 31, 2017 , under the definitions in the credit agreement, our consolidated leverage ratio was 1.1 and our consolidated interest coverage ratio was 29.4 . In addition, the credit agreement contains customary affirmative and negative covenants (subject to exceptions), including covenants that in certain circumstances limit our ability to incur liens or other encumbrances, make investments and acquisitions , incur indebtedness, enter into mergers, consolidations and asset disposition s, pay cash dividends after the occurrence of an event of default, change the nature of our business and engage in transactions with affiliates, as well as customary provisions with respect to events of default. We were in compliance with the covenants contained in our credit agreement at March 31, 2017 ; however, there can be no assurances that we will remain in compliance in the future.

Fair Value

Fair Value [Abstract]
Fair Value	1 2 . FAIR VALUE Fair value is defined as the price that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability Level 3: Unobservable inputs for the asset or liability We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As circumstances change, we will reassess the level in which the inputs are included in the fair value hierarchy. We utilize a third-party to value our interest rate derivatives. The interest rate derivatives are used to hedge the risk of variability from interest payment s on our borrowings (see Note 10 – Derivatives and Hedging Activity). A majority of the inputs used in determining the fair value of the derivatives is derived mainly from Level 2 observations which include counterparty quotations in over the counter markets. However, the credit valuation adjustments associated with the derivatives utilize Level 3 inputs , such as estimates of current credit spreads , to evaluate the likelihood of default by ourselves and our counterparties. We determined that these adjustments are not significant to the overall valuation of our derivatives. As a result, our interest rate derivatives are classified in Level 2 in the fair value hierarchy. In certain instances, our acquisitions provide for deferred contingent acquisition payments. These deferred payments are recorded at fair value at the time of acquisition and are included in other current and/or non-current liabilities on our consolidated balance sheets. We estimate the fair value of our deferred contingent acquisition liabilities using a probability-weighted discounted cash flow model. This fair value measure is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Fair value measurements characterized within Level 3 of the fair value hierarchy are measured based on unobservable inputs that are supported by little or no market activity and reflect our own assumptions in measuring fair value. The significant unobservable inputs used in the fair value measurements of our deferred contingent acquisition liabilities are our measures of the future profitability and related cash flows and discount rates. The fair value of the deferred contingent acquisition liabilities is reassessed on a quarterly basis based on assumptions provided to us by segment and business area leaders together with our corporate development and finance departments . Any change in the fair value estimate is recorded in the earnings of that period. During the three months ended March 31, 2017 , we recorded $1.2 million in other operating costs for a net increase in the liability and during the three months ended March 31, 2016 , no such adjustments were made, reflecting changes in the fair value estimate of the deferred contingent acquisition liability for cer tain acquisitions made in 2016 (see Note 3 – Acquisitions to the consolidated financial statements in our 2016 Form 10-K). The following table summarizes the changes in deferred contingent acquisition liabilities were as follows (in thousands):       For the three months ended  March 31,  2017 2016   Beginning Balance $ 1,723 $ 8,782  Accretion of acquisition-related contingent consideration 49 167  Remeasurement of acquisition-related contingent consideration 1,199 -  Payments - (49)  Ending Balance $ 2,971 $ 8,900  At March 31, 2017 , the carrying value of our bank debt approximated fair value as it bears interest at variable rates, and we believe our credit risk is consistent with when the debt originated . We consider the recorded value of our other financial assets and liabilities, which consist primarily of cash and cash equivalents, accounts receivable and accounts payable, to approximate the fair value of the respective assets and liabilities at March 31, 2017 based upon the short-term nature of the assets and liabilities. Our financial assets and liabilities measured at fair value on a recurring basis at March 31, 2017 and December 31, 2016 were as follows ( in thousands):    Quoted Prices in  Active Markets for Significant Other Significant  Identical Assets Observable Inputs Unobservable Inputs  (Level 1) (Level 2) (Level 3) Total  At March 31, 2017  Interest rate derivatives, net $ — $ 13 $ — $ 13  Deferred contingent acquisition liabilities $ — $ — $ 2,971 $ 2,971  At December 31, 2016  Interest rate derivatives, net $ — $ 64 $ — $ 64  Deferred contingent acquisition liabilities $ — $ — $ 1,723 $ 1,723
