Expert Judgment
Expert judgment is the application of specialized knowledge or training from individuals or groups with expertise in a specific area to guide project decisions.
Explanation
Expert judgment is one of the most widely used tools and techniques across nearly every PMBOK process. It involves consulting individuals or groups who possess specialized education, knowledge, skill, experience, or training relevant to the activity being performed. Sources of expert judgment include other units within the organization, consultants, stakeholders, professional and technical associations, industry groups, and subject matter experts.
Project managers rely on expert judgment when there is insufficient data for quantitative analysis or when the situation requires seasoned perspective. It is especially critical during project initiation and planning, where uncertainty is highest and decisions have the greatest downstream impact. Expert judgment should be documented to maintain transparency and support future decision-making.
While powerful, expert judgment carries the risk of cognitive bias. To mitigate this, PMI recommends combining expert judgment with other analytical techniques and, where possible, seeking input from multiple independent experts.
