Generally Accepted Project Management Practices

PMBOK v8 Definition

The PMBOK® Guide reflects the subset of the project management body of knowledge that is "generally accepted," meaning applicable to most projects most of the time, with widespread consensus that these practices have value and usefulness. This concept distinguishes the PMBOK® Guide as a guide to the body of knowledge, rather than the complete body of knowledge itself, focusing on practices that have achieved broad recognition and validation across industries, cultures, and project types.

Why It Matters for the Exam

This foundational concept appears frequently in PMI exam questions testing your understanding of the scope and purpose of the PMBOK® Guide. Expect questions that ask you to differentiate between "generally accepted" practices versus specialized or emerging practices, and to identify what the PMBOK® Guide does and does not cover. These questions often appear in the first section of the exam, testing your grasp of project management fundamentals.

Key Points to Remember (for the exam)

• Core Definition: "Generally accepted" means practices applicable to most projects most of the time, NOT all projects all of the time
• Consensus Requirement: Practices must have widespread consensus that they have value and usefulness
• Not Exhaustive: The PMBOK® Guide is a subset, not the complete body of knowledge
• Evolutionary Nature: What is "generally accepted" evolves over time (evidenced by the shift from Knowledge Areas to performance domains in v8)
• Industry Neutral: These practices apply across all industries, not just IT or construction
• Approach Agnostic: Generally accepted practices work with predictive, adaptive, and hybrid approaches
• Value-Based: The key criterion is proven value and usefulness in practice, not theoretical perfection

Typical PMI Exam Example

A project manager is leading a construction project in a country with unique regulatory requirements. The sponsor asks whether the PMBOK® Guide covers all necessary practices for this specific project. What should the project manager respond?

Answer: The PMBOK® Guide reflects generally accepted practices applicable to most projects most of the time, but it does not include all specialized or location-specific practices. The project manager should supplement the PMBOK® Guide with local regulatory knowledge and industry-specific standards.

PMI Exam Traps

• Trap: Confusing "generally accepted" with "universally required"

  • Reality: Generally accepted practices are applicable to most projects most of the time, but may not be appropriate for every unique situation

• Trap: Assuming the PMBOK® Guide contains the complete body of knowledge

  • Reality: The PMBOK® Guide reflects only a subset—the generally accepted portion—not the entire project management body of knowledge

• Trap: Thinking "generally accepted" means mandatory or prescriptive

  • Reality: These practices have widespread consensus on value, but the project manager must apply professional judgment to determine relevance

• Trap: Believing generally accepted practices never change

  • Reality: The PMBOK® Guide evolves with community input (evidenced by the 48,000 data points used for v8) and what is generally accepted shifts over time
