A) external projects such as managing a project for a client (such as installing a new information system or building a physical structure for another company), and

B) managing an internal project inside your own organization (such as a software upgrade or a major office relocation).

Take into consideration differences in project team members and their work responsibilities, project budgets, and the scope of the project work and outcomes expected.

Should there be any difference between managing an internal project for your own organization versus managing an external project for a client?

If "YES"... what is the difference? What are the differences in the behavior of the project manager, the manner in which the project is completed, the manner in which project team members are handled, etc.

If "NO", then why? How and why should internal projects and external projects be managed in the same way?
