生命是永恒不断的创造，因为在它内部蕴含着过剩的精力，它不断流溢，越出时间和空间的界限，它不停地追求，以形形色色的自我表现的形式表现出来。泰戈尔Project management information systems: An empirical study of their impact on project managers and project successOriginal Research ArticleInternational Journal of Project ManagementProject management information systems (PMIS) usually acquired by organizations as software packages are meant to provide managers with the decision-making support needed in planning, organizing, and controlling projects. However, the actual contribution of PMIS to project success or performance is still unknown. The purpose of this study is to empirically assess the quality of the PMIS presently used in organizations and to examine their impact on project managers and project performance, based on a PMIS success model. This model is composed of five constructs: the quality of the PMIS, the quality of the PMIS information output, the use of the PMIS, the individual impacts of the PMIS and the impacts of the PMIS on project success. Analysis of questionnaire data obtained from 39 project managers confirms the significant contribution of PMIS to successful project management. Improvements in effectiveness and efficiency in managerial tasks were observed here in terms of better project planning, scheduling, monitoring, and control. Improvements were also observed in terms of timelier decision-making. Advantages obtained from PMIS use are not limited to individual performance but also include project performance. These systems were found to have direct impacts on project success, as they contribute to improving budget control and meeting project deadlines as well as fulfilling technical specifications.Article Outline1.

This study considers the strategic and operational factors simultaneously to secure the efficacy of supplier selection (VS) on initial stage of new product development (NPD). We suggest strategic factors come from the suppliers management system itself (i.e., customer-, long-term-, and process-oriented criteria) while the related performances indices of supplier constitute operational factors (i.e., producer-, short-term- and outcome-oriented criteria). The work adopts suppliers process capability indices (PCIs) and process yields as operational factors to estimate their quality capabilities. The business process-oriented criteria related with the performance of business process improvement (BPI) are employed as the strategic criteria for supplier assessment visit. A fuzzy approach with supply risk consideration is employed then to aggregate the total scores of individual suppliers objectively. An empirical case study is performed to demonstrate the efficacy of the proposed system and to identify the best potential supplier(s) for further development. The results and processes of the case study also provide interesting managerial implications. The derived application of Herzbergs two-factor theory to the realm of supplier selection is discussed as well.Article Outline1. Introduction2. Literature review3. The research framework 3.1.
