What is the difference between program and project manager?

The difference between a program manager and a project manager can be summarised in the following way.

A project manager plans, monitors, and controls a specific project. They manage a project team, coordinate tasks, monitor progress, and ensure that project objectives are achieved within the defined constraints of time, budget, and scope.

A programme manager manages a group of related projects known as a program. They align the projects within the program with strategic objectives, manage interdependencies, and deliver the program's intended benefits. Program managers oversee the coordination of resources, stakeholder management, and ensuring the overall success of the program.
