Abstract
Customer Satisfaction is determined by the profit that a project produces based on investment to the project. Customer's requests are embodied as requirements for a project. Current project management doesn't provide practices of selecting appropriately requirements for the viewpoint of "managing projects" (i.e., multiple projects) and of the return on investment. The ERVM is the method for evaluating a value that is inherent in requirements for a project, and enables to manage of the ROI. The ERVM is still in the phase of the suggestion, and is expected in future practices. Therefore, it is important to support the users of the ERVM by providing a project management software tool. In this paper, we introduce to the ERVM that is the value evaluating method for requirements for a project, and describe the model for software support of this method. We also describe the prototype tool based on the model.
