The Project Management Body of Knowledge (PMBOK) is a collection of processes and knowledge areas generally accepted as best practice within the project management discipline.
As an internationally recognised standard (IEEE Std 1490-2003) it provides the fundamentals of project management, irrespective of the type of project be it construction, software, engineering, automotive etc.
The PMBOK9(r) 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.
