What is difference between project and program management?

The main difference between project management and program management is that project management is focused on the completion of a single project, while program management is focused on the overall management of a group of projects. Project management involves planning and organising tasks, resources, and timelines to complete a project, while program management involves overseeing multiple projects, coordinating resources and personnel, and ensuring that all projects within the program are completed on time and within budget.

Program management is used to ensure that all projects within the program are aligned and working towards the same overall objectives.
