(Summary of Key Concepts for Knowledge Areas)
PMBOK® Guide, page 673, Section X4.1
Key concepts for Project Integration Management include: Project Integration Management is the specific responsibility of the project manager and it cannot be delegated or transferred. The project manager combines the results from all the other Knowledge Areas to provide an overall view of the project. It is the project manager who is ultimately responsible for the project.
Projects and project management are integrative by nature, with most tasks involving more than one Knowledge Area.
The relationships of processes within the
Project Management Process Groups and between the
Project Management Process Groups are iterative.
