How do functional managers differ from project managers?

In a career setting, a functional manager is responsible for overseeing a specific function within an organization, such as a department or team, and is focused on managing and providing resources for their team‘s part of a project. On the other hand, a project manager oversees all phases of a project, including all departments and teams involved, and is focused on managing the processes without formal authority over people. The key differences between the two roles include the focus on people versus processes and the level of hands-on work with the project team.
