PMI Lexicon of Project Management Terms

The PMI Lexicon of Project Management Terms offers clear and concise definitions for nearly 200 of the profession’s frequently used terms.

For anyone involved in project, program, and portfolio management, the Lexicon is an essential resource to foster understanding and consistent usage of terminology. Use of standardized language promotes better communications among project teams and is an essential component of any profession.

Definitions in the Lexicon were developed by volunteer experts, and PMI standards committees are chartered to use the Lexicon terms without modification.

Version 3.1 offers insight into related terms, with a “See Also” feature in many of the definitions. For additional information about the new update, please see the Preface in the attached pdf version of the PMI Lexicon.
