The objective of this paper is to present an approach to comprehensively and quantitatively evaluate and promote the capabilities of organizational portfolio management. Based on the Organizational Project Management Maturity Model( OPM3),the process areas of organizational project portfolio management are identified through the questionnaire survey and further analysis,and five capability levels are put forward and described.Then the methods of Delphi,AHP and multi-layer fuzzy comprehensive evaluation are applied to construct a model of assessment and promotion. Finally,an illustrative example is presented to verify the proposed approach.The result objectively and accurately describes the project portfolio management capabilities of the organization,and shows that it is able to provide a theoretical basis for an organization to improve and enhance the project portfolio management.
Project portfolio management(PPM) is the centralized management method, process and technology in multiple projects. When multiple projects in the space industry are implemented, it provides an effective methodology to resolve the problems at the same time such as conflicts among models, decrease in design efficiency,and increase in target deviation. Hence, a PPM dedicated to multiple projects management in space enterprise is presented in this paper. Firstly, an analysis of features and contents in space enterprise portfolio management mode is performed by using PPM based on its specific strategic characteristics. Then, the principle and selection methods of PPM are provided as a reference for the future development of an enterprise. Finally, a multiple-level organization architecture including decision making layers, function management layers and project execution layers is proposed so as to adapt to possible changes in the multiple projects and correspond to the strategic development. As a consequence, a perfect matching mechanism to fit the changes in PPM modes is reached. In addition, the flow chart of PPM is designed and optimized by analyzing the implementation procedure of strategic target and project portfolio life-cycle, which is expected to realize the purpose of improving space enterprise management efficiency, project management capacity, innovation development and economic benefits.
