Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and such differences could be material to the financial statements. Revenue Recognition Software – Revenue Recognition, Revenue Recognition – Multiple-Element Arrangements Revenue Recognition There are no significant cancellation or termination-type provisions for the Company's software and hardware sales. Contracts for professional services provide for a general right, to the client or the Company, to cancel or terminate the contract within a given period of time (generally 10 to 30 days' notice is required). The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract. The Company may provide multiple services under the terms of an arrangement and is required to assess whether one or more units of accounting are present. Service fees are typically accounted for as one unit of accounting, as fair value evidence for individual tasks or milestones is not available. The Company follows the guidelines discussed above in determining revenues; however, certain judgments and estimates are made and used to determine revenues recognized in any accounting period. If estimates are revised, material differences may result in the amount and timing of revenues recognized for a given period. Revenues are presented net of taxes assessed by governmental authorities. Sales taxes are generally collected and subsequently remitted on all software and hardware sales and certain services transactions as appropriate.

Commitments and Contingencies From time to time the Company is involved in legal proceedings, claims and litigation related to employee claims, contractual disputes and taxes in the ordinary course of its business. Although the Company cannot predict the outcome of such matters, currently the Company has no reason to believe the disposition of any current matter could reasonably be expected to have a material adverse impact on the Company's financial position, results of operations or the ability to carry on any of its business activities.

For these leases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease and records the difference between the amounts charged to operations and amounts paid as accrued rent expense. The Company leases office space and certain equipment under various operating lease agreements. The Company has the option to extend the term of certain lease agreements.

Income Taxes [Abstract]
Income Taxes	10. Income Taxes The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Internal Revenue Service (the "IRS") has completed examinations of the Company's U.S. income tax returns or the statute of limitations has passed on returns for the years through 2010. The Company's 2011, 2012 and 2013 U.S. income tax returns are currently under examination by the IRS. The IRS has sought to disallow certain research credits on the Company's 2011 and 2012 U.S. income tax returns. The Company is actively appealing the IRS's initial findings. The Company believes the research credits taken are appropriate and intends to vigorously defend its position. The amount of adjustment, if any, and the timing of such adjustment is not reasonably estimable at this time. Under the provisions of the ASC Subtopic 740-10-25, Income Taxes - Recognition The Company's effective tax rate was 31.1% for the three months ended March 31, 2016 compared to 34.6% for the three months ended March 31, 2015. The decrease in the effective rate is primarily due to the research and development tax credit, which was not re-enacted by Congress for the three months ended March 31, 2015, but was adopted in December 2015 and therefore favorably impacted the current year quarter. The rate was also favorably impacted by the early adoption of ASU No. 2016-09 . Recent Accounting Pronouncements

Financial Instruments [Abstract]
Financial Instruments	11. Financial Instruments In the normal course of business, the Company uses derivative financial instruments to manage foreign currency exchange rate risk. Currency exposure is monitored and managed by the Company as part of its risk management program which seeks to reduce the potentially adverse effects that market volatility could have on operating results. The Company's derivative financial instruments consist of non-deliverable foreign currency forward contracts. Financial instruments are neither held nor issued by the Company for trading purposes. Derivatives Not Designated as Hedging Instruments Both the gain or loss on the derivatives not designated as hedging instruments and the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. Realized gains or losses and changes in the estimated fair value of foreign currency forward contracts that have not been designated as hedges were a net loss of $0.1 million and $0.2 million during the three months ended March 31, 2016 and 2015, respectively. Gains and losses on these contracts are recorded in net other expense (income) and net interest expense in the Unaudited Condensed Consolidated Statements of Operations and are offset by losses and gains on the related hedged items. The notional amounts of the Company's derivative instruments outstanding were as follows (in thousands): March 31, 2016 December 31, 2015 Derivatives not designated as hedges Foreign exchange contracts $ 5,893 $ 3,215 Total derivatives not designated as hedges $ 5,893 $ 3,215 Fair Value of Derivative Instruments The authoritative guidance defines fair value as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: ● Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities. ● Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. ● Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. The Company estimates the fair value of each foreign exchange forward contract by using the present value of expected cash flows. This considers the difference between the current market forward price and the contracted forward price for each foreign exchange contract and applies the difference in the rates to each outstanding contract. Valuations for all derivatives fall within Level 2 of the GAAP valuation hierarchy. The fair value of the Company's derivative instruments outstanding as of March 31, 2016 was immaterial. Derivatives may give rise to credit risks from the possible non-performance by counterparties. Credit risk is generally limited to the fair value of those contracts that are favorable to us. The Company has limited its credit risk by entering into derivative transactions only with highly-rated global financial institutions, limiting the amount of credit exposure with any one financial institution and conducting ongoing evaluation of the creditworthiness of the financial institutions with which the Company does business. The Company utilizes standard counterparty master agreements containing provisions for the netting of certain foreign currency transaction obligations and for the set-off of certain obligations in the event of an insolvency of one of the parties to the transaction. Within the Condensed Consolidated Balance Sheets (Unaudited), the Company records derivative assets and liabilities at net fair value.

Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and such differences could be material to the financial statements.
Revenue Recognition	Revenue Recognition Software – Revenue Recognition, Revenue Recognition – Multiple-Element Arrangements Revenue Recognition There are no significant cancellation or termination-type provisions for the Company's software and hardware sales. Contracts for professional services provide for a general right, to the client or the Company, to cancel or terminate the contract within a given period of time (generally 10 to 30 days' notice is required). The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract. The Company may provide multiple services under the terms of an arrangement and is required to assess whether one or more units of accounting are present. Service fees are typically accounted for as one unit of accounting, as fair value evidence for individual tasks or milestones is not available. The Company follows the guidelines discussed above in determining revenues; however, certain judgments and estimates are made and used to determine revenues recognized in any accounting period. If estimates are revised, material differences may result in the amount and timing of revenues recognized for a given period. Revenues are presented net of taxes assessed by governmental authorities. Sales taxes are generally collected and subsequently remitted on all software and hardware sales and certain services transactions as appropriate.

Commitments and Contingencies [Abstract]
Legal Claims	From time to time the Company is involved in legal proceedings, claims and litigation related to employee claims, contractual disputes and taxes in the ordinary course of its business. Although the Company cannot predict the outcome of such matters, currently the Company has no reason to believe the disposition of any current matter could reasonably be expected to have a material adverse impact on the Company's financial position, results of operations or the ability to carry on any of its business activities.
Operating Leases	Certain of the Company's operating leases contain predetermined fixed escalations of minimum rentals during the original lease terms. For these leases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease and records the difference between the amounts charged to operations and amounts paid as accrued rent expense.

Goodwill and Intangible Assets [Abstract]
Goodwill and Intangible Assets	Other intangible assets include customer relationships, non-compete arrangements, trade names, customer backlog, and internally developed software, which are being amortized over the assets' estimated useful lives using the straight-line method. Estimated useful lives range from less than one year to ten years. Amortization of customer relationships, non-compete arrangements, trade names, customer backlog, and internally developed software is considered an operating expense and is included in "Amortization" in the accompanying Unaudited Condensed Consolidated Statements of Operations. The Company periodically reviews the estimated useful lives of its identifiable intangible assets, taking into consideration any events or circumstances that might result in a lack of recoverability or revised useful life.
