This document summarizes one project manager's experience reconciling project management theory with real-world practice. It discusses some disconnects between PM processes and knowledge areas outlined in methodologies and the realities of managing projects. Specifically, it notes that while PM process groups are understood, properly rightsizing processes to projects and accounting for factors beyond the triple constraint of time, cost, and quality can be challenging. Managing stakeholder expectations and controlling scope creep are also areas where methodologies provide limited practical guidance.
