How Project Management Principles Create a Foundation for Performance Domains

PMBOK v8 Definition

A principle is a fundamental norm, truth, or value that gives guidance for the project manager and project team. The project management principles provide guidance for the mindset and behavior of people involved in projects as they influence and shape the performance domains to produce the intended outcomes. While there is conceptual overlap between the principles and the performance domains, the principles guide mindset and behavior, while the performance domains present broad areas of focus in which to demonstrate that mindset and behavior.

Why It Matters for the Exam

This concept appears frequently in PMI exam questions testing your understanding of the structural relationship between the foundational principles and the operational performance domains. Questions often present scenarios where you must distinguish whether a described action reflects a principle (mindset/behavior) or a performance domain activity (area of focus), and how principles guide the processes within each domain.

Key Points to Remember (for the exam)

• Foundation Relationship: Principles are the foundation of performance domains—they guide mindset and behavior, while performance domains are where that mindset and behavior are demonstrated.

• The 7 Performance Domains: Governance, Scope (including quality), Schedule, Finance, Stakeholders, Resources, and Risk. These are interactive, interrelated, and interdependent areas of focus.

• Principles Apply to All Domains: While all principles relate to all performance domains, some principles connect more strongly to specific domains than others.

• Operationalization: Each performance domain plays an important role in operationalizing project management principles by providing a structured approach to managing various aspects of a project.

• Process Guidance: Principles provide guidance to the processes in each performance domain—processes are the project management activities described as formal policies and informal procedures.

• Starting Point: Each performance domain begins with a treatise of the most important ideas, considerations, and concepts, which inform decisions regarding when and how performance domain activities should be practiced.

• No Weighting or Order: The seven performance domains are presented without specific weighting or order—they work in unison to achieve desired project results.

Typical PMI Exam Example

A project manager notices their team consistently delivers high-quality work but struggles with stakeholder communication. The project manager decides to review the project management principles to guide the team's mindset toward proactive stakeholder engagement. Which statement best describes this situation?

The principles guide mindset and behavior, which will influence how the team demonstrates stakeholder focus within the Stakeholder performance domain.

PMI Exam Traps

• Trap: Confusing principles with performance domains Reality: Principles = mindset and behavior guidance; Performance domains = broad areas of focus where those behaviors are demonstrated

• Trap: Thinking each principle applies to only one performance domain Reality: All principles relate to all performance domains, though some connections are stronger than others

• Trap: Believing performance domains are independent silos Reality: Performance domains are interactive, interrelated, and interdependent—they work in unison

• Trap: Assuming principles and performance domains are the same thing Reality: There is conceptual overlap, but principles are foundational guidance, while domains are structured areas of focus with processes

Quick Review Questions

1. A project team is deciding how to approach risk management for their project. According to PMBOK v8, what should guide their mindset and behavior before they select specific risk processes?

2. A project manager states that "the principles and performance domains are the same thing." Is this statement correct according to PMBOK v8? Why or why not?

3. During a project audit, the team demonstrates strong accountability and proactive ownership. In which part of the PMBOK v8 framework are these behaviors described?

4. A new project team asks where they should begin when planning project management efforts. What does PMBOK v8 suggest as the starting point for each performance domain?

5. How do the seven performance domains relate to each other according to PMBOK v8?
