全球化使得軟體開發活動轉移至新興或開發中國家，快速變動的商業環境則趨使軟體開發朝向敏捷開發演進，然而軟體境外開發產生工作分離現象，負面影響軟體開發績效，此外敏捷開發法與境外開發環境存在衝突，本研究將軟體開發方法視為一連續漸變的光譜，包含規劃導向、風險導向及敏捷開發等三階段，探討在境外開發的環境下，哪一類型的開發方法能夠擁有較好的績效表現，並能減緩工作分離的負面影響，其中軟體開發方法光譜與績效表現呈現曲線關係，工作分離負面影響敏捷開發端之績效表現，需求變動則負面影響規劃導向端績效表現，結論將從工作分離與需求變動程度觀點，分別探討不同情況下所應採取的專案執行方式。
Affected by globalization, software development activities have transferred to developing country. On the other hand, driven by turbulent business environments, software development methods have become more flexible like agile method. However, work dispersion derived from offshore software development has negative impact on performance. Besides, offshore environments have conflict with agile method in some aspect. There is a need to know the fit of between development methods and offshore modes. This research view development methods as a continuous spectrum, consisting of plan-driven, risk-driven and agile methods, and will probe which part of the spectrum perform better in offshore context and can alleviate the negative work dispersion effect on performance. The result shows that software development spectrum and offshore software development performance have curvilinear relationship. Work dispersion has negative impact on agile method, while requirements change has negative impact on plan-driven part. We’ll conclude from work dispersion and requirements change perspective, discussing how should practitioners conduct offshore project in different situations respectively.
