Service-driven IT solutions allow for a great deal of managerial flexibility and risk sharing between IS users and their service vendors.However,this flexibility brings an increased number of decision criteria for both clients (user firms) and vendors.In a service-driven solution,the contract contains many parameters which parties must negotiate.These parameters will affect not only the value of the solution or contract at hand,but also will affect the value of the overall portfolio of contracts a firm holds.Contractual parameters such as service and security level,service sourcing,timing,incentives and penalties in aggregate,present a web of endogenous and exogenous risk factors.These contractual risk factors will either amplify the overall risk expo-sure of a firm,or lessen it due to negative correlations which allow for strategic hedging of IT services contracts.Managers are faced with a fundamental tradeoff:how to maximize the profitability of services contracts while maintaining an acceptable level of risk exposure to the overall contract portfolio.New methods and quantitative tools are required to actively manage both individual contrac-tual profitability and overall portfolio value and risk tolerance.Thus,we ask the following fun-damental research questions:(1) How should an IT services vendor optimally set contractual parameters given an acceptable level of firm-wide contract portfolio risk?(2) How can we achieve a better understanding of risk exposure in IT services contracts to inform managerial de-cision making?We develop our evaluative approach using value-at-risk (VaR) concepts from financial economics,a theory base that offers unique potential for the study of IS management issues (Bakos and Kemerer 1992,Clemons and Weber 1990,Kauffman and Walden 2001).

服务导向的IT解决方案,允许大量的管理上的灵活性和分担风险之间的是用户和他们的服务供应商.然而,这种灵活性带来了日益增多的决定标准,双方的客户（企业用户）和供应商.在一个服务导向的解决方案,合同包含了许多参数,各方必须进行谈判.这些参数将不仅影响到价值的解决方案或合同在手,而且也将影响价值的整体投资组合的合同坚定持有.合同参数,如服务和安全水平,服务采购,时间,奖励和惩罚,在总结,目前网络的内源性和外源性危险因素.这些合约的风险因素,不是健全的整体风险博览-确定一个坚定的,或减轻由于它的负相关,其中,允许对冲战略,IT服务的合同.经理人正面临着一个根本权衡：如何最大限度的利润服务合约的同时,保持一个可接受的风险水平暴露于整体投资组合的合同.新的方法和定量的工具,必须积极管理个人contrac - tual的盈利能力和整体投资组合的价值和风险承受能力.因此,我们提出以下的乐趣- damental研究的问题：（ 1 ）应如何一IT服务供应商订定合约的最佳参数,给出了一个可接受的水平,坚定全合同投资组合风险?（ 2 ）我们如何能实现更好地了解风险,在IT服务合同,通知管理德-精度的决策?我们在发展评价方法,利用风险值（无功）的概念,从金融经济学,理论基础,提供了独特的潜力,为研究是管理问题（ bakos和kemerer 1992年,克莱蒙斯和韦伯1990年,考夫曼和Walden 2001年） .
