Abstract
In almost all software development projects, many risks are latent from the start. As a result, project managers have to resolve many problems related to QCD (Quality, Cost, Delivery) in the software development process. In order to ensure the success of a software project by the early planned solutions for such problems, effective implementation of project management is indispensable. In this paper, we quantitatively analyze the cause-and-effect relationships among the initial project risk, the problems of project management activity, the attainment level of QCD goals by using function-upgraded project data for embedded software. Based on this analysis, we discuss the techniques of effective project management to be improved for ensuring QCD goals of the project.
