Body of Knowledge
The Project Management Body of Knowledge is a set of standard terminology and guidelines (a body of knowledge) for project management. The body of knowledge evolves over time and is presented in "A Guide to the Project Management Body of Knowledge" (the "Guide to the PMBOK" or the Guide), a book whose sixth edition was released in 2017. The Guide is a document resulting from work overseen by the Project Management Institute (PMI), which offers the CAPM and PMP certifications.
