Managerial Perceptions of Project Stability

Abstract

This research investigated the importance of stability (ability of schedules to absorb disruption) to project outcomes. Managers involved in aviation systems development were surveyed for their perceptions of importance and usefulness for project attributes and performance management measures. Traditional measures of cost, schedule, performance, and earned value were compared to proposed measures of stability. Stability and earned value had both importance and usefulness to the managers. Stability was perceived to be as important as the more common measures. Perceptions differed depending on program size, scope, and stage of completion and between managers depending on experience and certification level.
