Project Management Body of Knowledge (PMBOK) by PMI
PMBOK comes from Project Management Body of Knowledge, which originated in the book A Guide to the Project Management Body of Knowledge (PMBOK Guide). it represents generally recognized good practices in the profession while reflecting project management’s continually evolving knowledge.
PMBOK was first developed by the Project Management Institute (PMI) as a white paper in the 1983 PMI Ethics, Standards and Accreditation Report in an attempt to document and standardize generally accepted project management information and practices. It is now in its fourth edition (2008), the PMBOK® Guide–Fourth Edition continues the tradition of excellence in project management with a standard that is even easier to understand and implement, with improved consistency and greater clarification.
The PMBOK Guide is process-based, meaning it describes work as being accomplished by processes. This approach is consistent with other management standards such as ISO 9000 and the Software Engineering Institute’s CMMI. Processes overlap and interact throughout a project or its various phases.
