Two project managers A and B are working in the corporate offices of a popular fast-food franchise. They are both studying for their PMP certification. They have a spirited debate. A thinks the project sponsor is responsible for managing and performing project integration activities, while B insists it is the project manager. Who is correct?

Project integration involves coordinating and integrating various project management processes and activities to ensure the successful completion of the project. It includes activities such as developing the project charter, creating the project management plan, coordinating project execution, managing project changes, and facilitating communication among various stakeholders. According to the Project Management Institute (PMI) and the Project Management Body of Knowledge (PMBOK Guide), the responsibility for managing and performing project integration activities lies with the project manager, not the project sponsor.
