A Guide to the Project Management Body of Knowledge: (Pmbok Guide)

The PMBOK9 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.

• Standard language has been incorporated throughout the document to aid reader understanding.
• New data flow diagrams clarify inputs and outputs for each process.
• Greater attention has been placed on how Knowledge Areas integrate in the context of Initiating, Planning, Executing, Monitoring & Controlling, and Closing process groups.
• Two new processes are featured: Identify Stakeholders and Collect Requirements.

The PMBOK Guide is a standard for the project management profession. Its intention is to serve as a guide to the body of knowledge within the project management community and as practiced by members of the profession. There is no single document that contains the project management body of knowledge. Indeed, some of it is not published at all but, rather, is simply recognized as good practices and norms within the profession. This body of knowledge is growing every day.

The PMBOK Guide is not intended to be used to learn project management or project management concepts. It's especially not intended to teach or suggest PM techniques or methodologies.

This project management book is not a "how to" book nor is it a description of a methodology. It's a standard, not a methodology. PM professionals and the organizations they work for can use the PMBOK Guide as a guide for developing their own methodologies or for creating organization standards. 

It's particularly important to understand that it is not a standard or specification for the examination portion of the PMP certification. For one thing, at least 30% of the material on the examination is not covered by the PMBOK Guide. (There IS an exam on the PMBOK Guide. It's the CAPM exam, which only covers knowledge of the PMBOK Guide.)

While the PMBOK Guide only changes once every 4 years, the exam component of the PMP credential is constantly changing. Much of the material that showed up in the 4th (2008) edition of the PMBOK Guide has ALREADY been showing up on the PMP exam for several years - e.g., PTA, TCPI, etc. PMBOK Guide 4th edition came out in December, 2008, but these topics have been showing up on the PMP exam as early as 2006. The group at PMI that develops the standards (such the PMBOK Guide, the Standard for Risk Management, etc.) and the group at PMI that develops the the certifications and their corresponding exams (such as PMP, CAPM, PMI-SP, etc.) are two separate groups that DO NOT interface with each other. They are two separate groups. If anything, the standards group looks at the work that the credential group (PMP, CAPM) does and uses it as one of the many inputs for what they put into the standards such as the PMBOK Guide.
