The frontier between Kingdom of The Project Manager and Republic of the Team Leader is subtle and, too often, unexplored.
Projects will need planning on the short term to keep them within the company’s strategy, and will need several sorts of management on the mid-term.

“[Project Manager’s] job is not to advocate for the project, but to be objective […] and determine what is working, what needs improving, and what must be jettisoned. This takes the project manager out of the role of managing a project team and into the frontier of leading both the team and the stakeholders.” (American Management Association Play book, T.Williams)

Professor X, as the Project Manager, have to have many things in his brain. Both from within the team and from the environment. Interferences from other organizations or from the government.
