A Continuous Stakeholder Management Method throughout the System Life Cycle and Its Evaluation

We propose a method of continuously managing the stakeholders and changes in requirements throughout the life cycle of information systems. In the conventional methods of stakeholder analysis, the stakeholders are identified when capturing the requirements with the main objectives of identifying the source of the requirement and the degree of impact. However, stakeholders change along with the progress of the life cycle and cause the change of requirements. In this article, we propose a continuous stakeholder management method. The proposed method enables to: 1) model the interactions of stakeholder requirements that change along with life cycle, 2) to evaluate the interactions with a contribution/risk evaluation matrix, and 3) to identify conflicts between stakeholder requirements. We applied the proposed method to a development of a large-sale e-Government system, and demonstrate the validity and effectiveness of the method.
