過去在系統開發專案績效調查指出雖然系統開發的技術進步迅速,系統開發的成功率依然很低。從社會—技術之觀點,系統開發研究在這問題上發現影響系統開發成敗最主要的原因是來自商業和技術的變動。為了提高其專案效度,開發團隊應具備應變能力來因應商業及技術之變動。系統開發團體應變能力因此被延伸成概念,目的是用來描述開發團隊應因商業和技術變動之能力。此外,本研究從社會資理論的觀點去探究影響系統開發團隊應變能力的存在因素。最後本研究發現團隊效能是影響系統開發團體應變能力和系統開發專案績效之間的中介變項。本研究發展出了一個理論架構來描述概念與概念之間的存在關係。
Surveys on information system development (ISD) project performance suggest that while much improvement has been made in ISD technology, the project success rate remains low. ISD research based on the socio-technical perspective suggests that two sources of socio-technical change have a bearing on the performance of ISD projects: business requirements and development technology. To enhance project effectiveness, ISD teams need to be flexible in the face of the constant changes from business and technical environments where they operate. The construct, ISD Team Flexibility, is used to describe an ISD team’s capability to respond to changes from socio-technical environment. Furthermore, drawn on social capital view, this study explores the factors explaining the variation of SDTF among ISD teams. Finally, this study posits that the impact of SDTF on project performance is mediated by team efficacy. A model depicting the nomological relationships between the constructs is developed.
