The certification validates the best practices in project management: project management, role allocation, project breakdown, etc.
The PMP is based on a body of knowledge in project management (PMBOK), including subjects such as scope, costs, risks, etc. The PMP certification validates both the understanding of processes and the acquisition of project management skills, regardless of the method used.
