Practice it freeExplanation
Expert judgment is one of the most frequently used tools and techniques across the PMBOK Guide, appearing in nearly every knowledge area and process group. It involves seeking input from qualified individuals who can provide insights that the project team may lack. Sources of expert judgment include subject matter experts within the organization, consultants, industry groups, professional associations, and stakeholders with relevant experience.
The value of expert judgment lies in its ability to fill knowledge gaps, validate assumptions, and support decision-making when data alone is insufficient. For example, during Develop Project Charter, expert judgment helps assess whether the business case is viable. During Develop Project Management Plan, experts advise on which processes and approaches are most appropriate. During risk identification, experts draw on past experience to identify threats and opportunities.
It is important to document the basis for expert judgment so that decisions can be traced and justified. The project manager should identify the appropriate experts based on the nature of the decision and ensure that biases are managed. Expert judgment is not a substitute for data analysis — it is most effective when combined with quantitative and qualitative techniques.
