Project management standards provide a common language for all project participants. They encourage formal recognition of responsibilities within a project and focus on what a project is supposed to deliver, why, when and from whom. The Project Management Body of Knowledge (PMBOK® Guide) by the Project Management Institute (PMI®) is the international standard on project management.
It is more and more used in companies because project managers are using the same way of executing projects, same vocabulary etc…
Project Management Professional (PMP®) is the highest PMI professional credential and became the international recognized benchmark within project management. In consequence the PMP® Certification is only awarded to experienced project managers.
It recognizes project management professionals who have attained the knowledge and experience to oversee all aspects of project management including initiation, scheduling, quality, procurement, and communications issues. It demonstrates that you have mastered essential project management skills and knowledge.
