在資訊系統委外的相關議題中，委外建置專案團隊之績效管理是受到較多關心的議題。管理者期望組織內外成員所組成之開發團隊能提高委外績效，使新系統能成功上線。基於資訊系統委外績效對於企業的重要性，本研究以交互記憶系統理論，探討資訊系統委外績效與交互記憶系統的相關性，企圖建立資訊委外績效管理之關鍵因素。本研究以個案研究法，由團隊成員中之業主及委外廠商雙方的角度來探討影響委外績效的因素，包括：競爭性目標導向、業主及委外廠商雙方專案經理人的領導風格對委外績效之影響，分析業主和委外廠商在資訊委外運作過程的評價認知差異性，提供雙方訂定委外成效考核標準的參考，探討影響委外企業與承包商合夥關係的重要因素。 研究發現交互記憶系統會影響委外團隊績效；且競爭性目標導向會對委外團隊績效產生負向影響。此外，研究發現認知差異項目少，委外績效較好，認知差異項目多，委外績效較差。本研究發現可以實務見解供業主及委外廠商參考，期能提升資訊委外建置專案團隊績效之管理。 In the relation of the information system outsourcing’s issue, the performance management is the most interest concerned for the outsourcing project team. The Managers expect all of the team members that include the contract providers and contractor can be improved the performance of the information system outsourcing and helped the new system completed on time and make it successful. The research is used the “transactive memory system theory” to investigate the relationship of the outsourcing‘s performance and the transactive memory system, Those are the main factor and significance for the enterprise. Also, the research is used the “Case Study” method, the method is about the view between the contract providers and contractor to find out what is the effective factors of the Outsourcing performance, which include the transactive memory system, the competiveness objective orientations, the leadership style on transactive memory system and outsourcing performance, the perception gap between the contract providers and contractor, and the partnership between contract providers and the contractor for information system outsourcing. Finally, the research discovered the transactive memory system will influence the outsourcing performance and the competiveness objective orientations will have negative impact on the outsourcing team performance. In addition, the less cognitive differences, then the performance of outsourcing is better, the more cognitive differences, then the performance of outsourcing is bad. Otherwise, the study supply the real cases view of some projects to the contract providers and contractor for reference, and hoping to improve the performance of information system outsourcing building the project management team.
