The term "project management approach" is not a standard term and can mean different things.
Project management approach can mean one of the following (depending on the context):
- The project management methodology: What kind of methodology we are going to use for a project. For example, "we chose the waterfall project management approach for our project"
- The leadership style applied to manage the project: For example, "this project manager uses the servant leader leadership style as a project management approach"
- Using project management to manage projects: In companies that do not use project management, the PM approach means applying project management to manage projects. For example, "We will adopt the project management approach to manage projects in our company henceforth".
