The Project Management Body of Knowledge (PMBOK) is an inclusive term that de-
scribes the sum of knowledge within the profession of project management. As with
other professions such as law, medicine, and accounting, the body of knowledge rests
with the practitioners and academics who apply and advance it. The full PMBOK in-
cludes knowledge of proven, traditional practices which are widely applied as well as
knowledge of innovative and advanced practices which have seen more limited use.
This chapter defines and explains several key terms and provides an overview of
the rest of the document. It includes the following major sections:
1.1 Purpose of this Document
1.2 What is a Project?
1.3 What is Project Management?
1.4 Relationship to Other Management Disciplines
1.5 Related Endeavors

The primary purpose of this document is to identify and describe that subset of the
PMBOK which is generally accepted. Generally accepted means that the knowledge
and practices described are applicable to most projects most of the time, and that
there is widespread consensus about their value and usefulness. Generally accepted
does not mean that the knowledge and practices described are or should be applied
uniformly on all projects; the project management team is always responsible for
determining what is appropriate for any given project.
This document is also intended to provide a common lexicon within the profes-
sion for talking about project management. Project management is a relatively young
profession, and while there is substantial commonality around what is done, there is
relatively little commonality in the terms used.
This document provides a basic reference for anyone interested in the profes-
sion of project management. This includes, but is not limited to:
• Project managers and other project team members.
• Managers of project managers.
• Project customers and other project stakeholders.
• Functional managers with employees assigned to project teams.
• Educators teaching project management and related subjects.
• Consultants and other specialists in project management and related fields.
• Trainers developing project management educational programs.
As a basic reference, this document is neither comprehensive nor all-inclusive.
Appendix E discusses application area extensions while Appendix F lists sources of
further information on project management.
