Human resource management part of the lecture focuses on project interface, staffing requirements, and constraints. In the constraints, it talks about organizational structure and describes weak vs. strong matrix.
For example, how much power the project manager has over his team. Can a director of a another department take away one of your team members?

My question to everyone who works in industry is, was there ever a case where a major team player was placed on another project and removed from your team? If yes, how did that change the project timeline or tasks. How do project managers deal with this sort of change if a director from a another department takes away one of your major team members?
