Abstract

Project portfolio benefits (PPBs) are typically regarded as a key feature for successful project portfolios in practice. However, there is little prescriptive knowledge that offers guidance on how to tackle the realisation and improvement of PPBs. To narrow this research gap, we develop a systematic assessment model to analyse and optimize PPBs. Innovatively considering the recessive benefits resulting from synergies among different project components, four subsystems of PPBs are identified. Subsequently, by synthesizing the interrelations within and between subsystems, a system dynamics model is developed to assess PPBs dynamically. Then, a numerical example is adopted to validate the applicability and effectiveness of the proposed model. It can be concluded that the model is exploitable in academia and practice. For academia, this study expands benefit management tools and provides a theoretical basis for project portfolio benefit optimization. For practitioners, the straightforward model and procedure contribute to enhancing the management of PPBs.

摘要

项目组合收益 (PPB) 通常被视为在实践中成功的项目组合的关键特征。但是，几乎没有规定性知识可以指导如何解决 PPB 的实现和改进。为了缩小这一研究差距，我们开发了一个系统的评估模型来分析和优化 PPB。创新地考虑不同项目组成部分之间的协同作用产生的隐性收益，确定了 PPB 的四个子系统。随后，通过综合子系统内部和子系统之间的相互关系，开发了一个系统动力学模型来动态评估 PPB。然后，通过数值算例验证了所提模型的适用性和有效性。可以得出结论，该模型在学术界和实践中是可利用的。对于学术界来说，本研究扩展了效益管理工具，为项目组合效益优化提供了理论基础。对于从业者而言，简单明了的模型和程序有助于加强 PPB 的管理。
