Abstract

This paper presents a method for analyzing the impact software project factors have on project success as defined by project success factors that have been prioritized. It is relatively easy to collect measures of project attributes subjectively (i.e., based on expert judgment). Often Likert scales are used for that purpose. It is much harder to identify whether and how a large number of such ranked project factors influence project success, and to prioritize their influence on project success. At the same time, it is desirable to use the knowledge of project personnel effectively. Given a prioritization of project goals, it is shown how some key project characteristics can be related to project success. The method is applied in a case study consisting of 46 projects. For each project, six success factors and 27 project attributes were measured. Successful projects show common characteristics. Using this knowledge can lead to better control and software project management and to an increased likelihood of project success.
