Lost Roots: How Project Management Came to Emphasize Control over Flexibility and Novelty

Abstract

The discipline of project management (PM) adheres to the dominant model of the project life cycle or phased stage-gate approach to executing projects. This implies a clear definition of mission and system are given at the outset (to reduce uncertainty), and subsequent execution in phases with decision gates. It contrasts with approach applied in the seminal projects that are credited with establishing the foundation of the discipline in the 1940s and 50s. Those projects started out with missions that were beyond the currently possible; any solutions had to emerge over time. They succeeded by a combination of parallel trials (from which the best would then be selected) and trial-and-error iteration (allowing for the modification of solutions pursued over a period of time). Although the success of these approaches was well documented and explained by scientific study in the 1950s, today they seem to fly in the face of accepted professional standards, making managers uncomfortable when they are encountered. The explanation for this contradiction has its roots in the 1960s, when the so-called McNamara revolution at the Department of Defense (DoD) gave a control orientation to the PM discipline. This shift was cemented by the codes and practices of the DoD and NASA, contemporary scientific writing, and the foundation of the Project Management Institute, a professional organization that translated the standard into the educational norm for a generation of project managers.
