使用者面對企業導入資訊系統所扮演的角色逐漸受到重視。早期文獻強調著使用者參與和使用者涉入，而使用者領導權與使用者主導權(User Ownership)也更進一步地指出各使用者部門的重要性。隨著這樣的趨勢，使用者與資訊人員之間的關係是值得注意，而夥伴關係也被證實是資訊系統導入的關鍵因素。本研究主要是探討專案導向、心理層面的使用者主導權(User Ownership)對成功的系統導入的影響，也納入使用者與資訊人員間的夥伴關係以及資訊人員的企業擁有權(IT Professional Business Ownership)對使用者主導權在系統導入成功的影響。 曾參與過專案的Key User是本研究問卷的對象，回收有效問卷共132份。研究結果證實使用者主導權(User Ownership)與資訊系統導入成功有正向的關係，使用者主導權是影響系統導入成敗的因素之一，而資訊人員對企業的知識與責任也能增強使用者主導權對資訊系統導入成功的影響，再者，使用者主導權能部分地透過使用者與資訊人員間的夥伴關係來影響資訊系統導入的成功。 Individual role of users toward information systems (IS) implementation is gaining importance and complication. Earlier literature stressed on the user participation and user involvement. Line leadership and user ownership are brought about to further highlight the importance of users in the line department. Along the development, user-IS relationship is always the primary concern and partnership is a proven critical success factor of IS implementation. In this paper, primarily we are to examine the effect of project-oriented, psychological user ownership on the successful implementation of IS. Also we want to understand the effect of the partnership and the business ownership of IT professionals on the prior relationship. Key users are the analysis units in our study on account of their engagement in process assessment, analysis, system design and interaction with IT professionals. We developed a questionnaire with most questions items from empirically tested instruments and e-mailed to our target users of pre-selected companies. After the analysis of 132 valid empirical data, the research findings show that there is a positive relationship between user project ownership and the IS implementation success. User project ownership indeed contributes significantly to the IS project success. The business knowledge and responsibility of IT professionals is also enhancing the effect of user project ownership on the IS project success. Further, empirical data showed that sound user-IT partnership is essential for the business to fully exploit information technology and attain its maximum performance
