Role comparison

Scrum Master vs Project Manager

Project Managers control projects — they own the plan, timeline, and budget. Scrum Masters facilitate teams — they protect the team from interference and help them improve how they work. Both coordinate work; neither is the boss.

Project Manager

Owns the plan, timeline, and budget. Accountable for delivering the project on time and within scope.

Scrum Master

Owns the team's process and health. Removes obstacles, protects sprint focus, and coaches continuous improvement.

The philosophical difference

Project Managers believe in predicting and controlling. They create detailed plans, track against them, and manage deviations. The assumption is that requirements can be known upfront and the job is to execute against them faithfully.

Scrum Masters believe in inspecting and adapting. They create conditions where teams can respond to change, learn quickly, and continuously improve. The assumption is that requirements will evolve, and the job is to help the team navigate that evolution effectively. Neither philosophy is wrong — they are appropriate for different kinds of work.

Fixed-scope IT projects where requirements are stable
