A Guide to The Project Management Body of Knowledge – Third Edition (PMBOK® Guide)
A project management standard developed by the Project Management Institute (PMI).
In 1987, PMI published the first Project Management Body of Knowledge (PMBOK®) in an attempt to document and standardize generally accepted project management information and practices. The current edition, A Guide to the Project Management Body of Knowledge (PMBOK® Guide), Third Edition (2004), is a basic reference for anyone interested in project management. It provides a common lexicon and consistent structure for the field of project management.
The PMBOK Guide is widely accepted to be the standard in project management, although it has its critics.
In addition to the "PMBOK Guide", a must have for all those studying for PMI certification will be Q & As for the PMBOK Guide.
