Project Management Knowledge

Project Management Body of Knowledge (PMBOK)

The Project Management Body of Knowledge (PMBOK) is a publication of the Project Management Institute (PMI). The first version of the PMBOK was published in 1987, the second version in 1996, the third version in 2004, the fourth in 2008, and the fifth in 2013. Members of the PMI can download a digital copy of the PMBOK for free.

The PMBOK describes the entire quantity of theory and learning that encompasses the practice of project management, including formal written frameworks of practice as well as previously informal and unwritten knowledge.There are five process groups (or steps) and nine knowledge areas in project management. Each of the nine knowledge areas in itself contains the five process groups. Each knowledge area needs all five process groups in order to function. Every process in a project management plan becomes interrelated to at least one knowledge area and one process group.

As the PMBOK includes dynamic, integrative processes that are in constant evolution as practice grows and changes,  the PMBOK is updated on a frequent basis. Similar to other disciplines, the content of the project management body of knowledge is defined, tested, and reformed by the individuals who utilize and foster increasing knowledge within the realm of project management. However, the PMBOK is not a project management training book. In fact, it is rather hard to read since it is simply a description of the processes 🙂



  1. could you please enlighten me as to whether the PMBOk is unique to the PMI or whether it is a universal compendium resourced by all the different PM groups such as PMA and IPMA?


  2. The PMBOK is a standard published by the PMI, the IPMA has a different standard. However, last year, the PMI and the IPMA signed a collaboration agreement, let’s see whether there will be a unique standard in the future…
