Relationship between Project Management Principles and Project Performance Domains

1.3 CHANGES TO THE PMBOK® GUIDE

This edition of the PMBOK® Guide focuses on delivering outcomes regardless of the approach used by the project team. However, project practitioners using the PMBOK® Guide also benefit from some level of understanding of how to deliver projects.

This edition is very different from the inputs, tools/techniques, and outputs (ITTOs) from previous editions of the PMBOK® Guide. In the previous editions, the ITTOs supported implementation of various processes used in project management. The shift from a process-based standard to one based on principles necessitates a different approach for thinking about the various aspects of project management. Thus, the project performance domains represent a group of related activities that are critical for the effective delivery of project outcomes. There are eight project performance domains in this guide.

Tailoring is the deliberate adaptation of the project management approach, governance, and processes to make them more suitable for the given environment and the work at hand. The tailoring process is driven by the guiding project management principles, organizational values, and organizational culture.

In embracing the full spectrum of project approaches, this edition of the PMBOK® Guide recognizes that no publication can capture every tool, technique, or practice that project teams might use. Therefore, this edition presents an array of commonly used models, methods, and artifacts that project practitioners can use to accomplish their work.
