Study PMBOK 8 Roles That Make Projects Work: key concepts, common traps, and exam decision cues.
This chapter turns PMBOK 8 role language into a more usable map. The goal is not to memorize titles. The goal is to understand what work has to be done, who usually owns which decisions, and how role confusion creates weak exam answers.
Use the section pages in order. Start with project functions rather than titles, then move into the core roles around sponsors, project managers, teams, customers, and product roles, and finish with the support structures around PMOs and shared services.
The most common mistake in this topic is title fixation. Good project management is not about assuming one person should do everything. It is about matching responsibility, decision rights, and support capability to what the situation actually needs.
