The Evidence-Based Research Process for Development

PMBOK v8 Definition

The development of the PMBOK Guide—Eighth Edition was based on a multiphased research effort engaging stakeholders on a global level, with PMI partnering with a third-party consulting firm to guide research and ensure the study was free from organizational bias. This evidence-based approach yielded approximately 48,000 data points through qualitative and quantitative research conducted over the course of 2023. The research consisted of three phases: Phase 1—Qualitative (live, chat-based discussions with project managers from seven countries), Phase 2—Quantitative (online survey to approximately 64,000 professionals with over 3,400 completions), and Phase 3—Draft feedback (25 volunteers iterating toward a full draft, yielding nearly 9,000 comments and suggestions).

Why It Matters for the Exam

This concept appears frequently in PMI exam questions testing your understanding of how the PMBOK Guide itself is developed and validated, particularly in questions about the credibility and authority of the standard. You will see it in situational questions asking about the basis for project management best practices, and in questions that test whether you recognize that the PMBOK Guide is evidence-based rather than opinion-based.

Key Points to Remember (for the exam)

• Research Foundation: PMI conducted qualitative AND quantitative research, not just one type
• Bias Prevention: A third-party consulting firm was used to ensure the study was free from organizational bias
• Three Phases: Phase 1 (Qualitative - discussions), Phase 2 (Quantitative - survey), Phase 3 (Draft feedback - volunteer team)
• Global Representation: Participants included seven countries in Phase 1, and all PMI regions in Phase 2
• Participant Requirements: Phase 1 required familiarity with the seventh edition AND at least one prior edition
• Survey Scale: Phase 2 survey sent to approximately 64,000 professionals, with over 3,400 completions
• Community Input: Nearly 9,000 comments and suggestions were received on the draft

Typical PMI Exam Example

A PMI exam question might describe a project manager who questions whether the PMBOK Guide is truly representative of global project management practices. The correct answer would reference that PMI conducted a multiphased research effort with stakeholders on a global level, including participants from seven different countries in the qualitative phase and representation across all PMI regions in the quantitative phase.

PMI Exam Traps

• Trap: Thinking the research was only quantitative (survey-based)

• Reality: The research included BOTH qualitative (Phase 1 discussions) AND quantitative (Phase 2 survey) phases

• Trap: Assuming PMI conducted the research internally without external oversight

• Reality: PMI partnered with a third-party consulting firm to ensure the study was free from organizational bias

• Trap: Confusing the number of phases or their sequence

• Reality: Phase 1 is Qualitative, Phase 2 is Quantitative, Phase 3 is Draft feedback—in that exact order

• Trap: Believing the draft was finalized without community review

• Reality: Phase 3 yielded nearly 9,000 comments and suggestions from the community
