The purpose of this study was to determine the relative importance of six criteria of project success and to develop a composite criterion of educational project success. Criteria considered were schedule, cost, quality/performance, follow-onwork, spin-of benefits, customer/client satisfaction, and overall project success. Two hundred and six people associated with a sample of 146 educational projects first ranked the criteria and then rated their own projects accordingly. A number of diagrams graphically present the relative importance of the various criteria as perceived by different groups of respondents. Findings of the study showed that achieving project objectives was considered most important and meeting time and cost constraints was considered rather unimportant in determining the success of projects. A copy of the survey instrument used to gather data for the study is included in the appendix. (Author/JG)
