A study was conducted to identify factors contributing to the success of instructional development projects. Success factors derived from factor analysis were compared with those in a previous study (Lawrason and Hedberg, 1979), and values obtained on the prediction model for this study were compared with those in the study cited. The Survey of Instructional Development Projects was administered to 220 higher education administrators and others with instructional development positions. Twenty-two factors were reported as contributing to the success of a project; among the high-ranking factors were: expertise of support staff, faculty participation and commitment, provision of financial resources, administrative support and commitment, and incentives for faculty participation. Twenty factors were reported as limiting the success of a project; among those with a high ranking were: lack of faculty participation, lack of time to plan, lack of compensation for faculty participation, and competing institutional projects. Four tables and one figure summarize the results. Contains 37 references. (KM)
