PMBOK stands for Project Management Body of Knowledge and it is the entire collection of processes, best practices, terminologies, and guidelines that are accepted as standards within the project management industry. Because the body of knowledge is constantly growing as practitioners discover new methods or best practices, it must be updated and disseminated. This is an effort that is overseen by the Project Management Institute (PMI), the global not-for-profit member association of PM professionals which captures and publishes the PMBOK within the book, A Guide to the Project Management Body of Knowledge (PMBOK Guide). The first edition of the PMBOK Guide was published in 1996. It is now on its fifth edition, which was published in 2013. Read a more in-depth discussion on PMBOK.
