近年來，許多公司面臨需要透過資訊科技來獲取競爭優勢。各產業對於資訊系統的要求越來愈多，促使資訊系統的開發工作越加複雜，而使得成功完成資訊系統的開發變的日益困難。 軟體工程協會指出軟體能力成熟度整合模式(Capability Maturity Model Integration, CMMI)強調軟體開發需要追求開發程序的改善與程序的最佳化。透過程序的改善以降低軟體開發專案失敗的機率。根據創意的定義，資訊系統開發程序的改善是團隊創意的表現。 目前少有研究從創意的觀點探討資訊系統開發程序的改善。根據社會認知理論指出效能信念是解釋行為/產出的關鍵元素。學者們也證明創意自我效能對於創意的重要性。到目前為止，效能與創意的連結僅限於個人層次的研究。因此，本研究將以資訊系統開發程序改善為研究情境，進行集體效能與創意文獻的連結，提出資訊系統開發團隊集體創意效能之概念，並探討集體創意效能的前置因素與了解干擾集體創意效能形成的因素。 本研究採用部分最小平方法 (Partial Least Squares)，分析98組開發資訊系統的學生團隊與61組開發資訊系統的業界團隊資料，以驗證研究模型。結果指出在學生團隊方面，團隊知識程度、成就動機、團隊知識整合能力會正向影響集體創意效能的形成；團隊互動程度會干擾團隊知識程度與集體創意效能的關係、專案複雜度會干擾團隊知識程度與集體創意效能的關係以及干擾團隊知識整合能力與集體創意效能的關係。在業界團隊方面，團隊知識程度、成就動機、團隊知識整合能力會正向影響集體創意效能的形成；團隊互動程度會干擾團隊知識程度與集體創意效能的關係、專案複雜度會干擾團隊知識程度與集體創意效能的關係、成就動機與集體創意效能的關係以及團隊知識整合能力與集體創意效能的關係。此外，本研究亦探討在不同專案複雜度的情境中，影響集體創意效能之前置因素。 / Numerous companies have recently employed information systems to obtain a competitive edge. The demand for many new and different information system (IS) applications has increased the scope and complexity of IS developing. Developing successful IS projects became difficult. Software Engineering Institute proposed Capability Maturity Model Integration (CMMI) that emphasized process optimization of software development. The improvement in software process can reduce the probability failure in development software. According to the definition of creativity, the improvement in software process is team creativity. However, there are few studies which discuss the issues about systems development process improvement from creative perspective. According to the social cognitive theory, efficacy is a key factor for interpreting behavior/products. Scholars demonstrated that creative self-efficacy is important to creativity. Previous researchers which studied the potential link between efficacy and creativity are focus on individual level. Thus, this study combined the literatures of collective efficacy and team creativity to propose a new construct (Collective creative efficacy, CCE) for information systems development teams, and explore the influences and moderators for CCE. 98 student project teams and 61 industry project teams are surveyed. Partial least squares (PLS) results demonstrate that team knowledge, achievement motivation and knowledge integration ability positively influenced CCE, team interaction positively moderated the relationships between team knowledge and CCE, and project complexity negatively moderated the relationships between team knowledge and CCE, and the relationships between knowledge integration capability and CCE in both samples. Project complexity positively moderated the relationships between achievement motivation and CCE in the model of industry project teams. An attempt is also made to understand the antecedents of CCE in different project complexity.
