Plan and Manage Schedule: Execution

A project schedule in its planning phase is a frictionless, perfect mathematical simulation of the future. The moment execution begins, that simulation collides with organizational physics. Dependencies overlap unexpectedly, resource constraints emerge like sudden traffic jams, and work expansions expose hidden risks. The transition from planning to execution is the transition from theory to reality. Your role as a project manager shifts from architecting the ideal path to navigating the actual one. This requires a relentless focus on measuring empirical truth against expectations, diagnosing variations, and manipulating project variables to protect the final delivery date.
