Group Project: Nominal Group Technique for Decision-Making

PMBOK v8 Definition

The nominal group technique is a structured method used to facilitate group decision-making by gathering input from participants in a systematic manner. This technique was developed to address the challenges of chaotic and unproductive discussions, particularly in large groups dealing with controversial topics. It helps project teams solve problems, influence actions of their stakeholders, and increase stakeholder support for the work and outcomes of the project, thus improving performance.

Why It Matters for the Exam

PMI exam questions frequently test the nominal group technique as a key decision-making tool within the Planning process group. You will encounter this concept in situational questions where a project manager needs to achieve consensus among diverse stakeholders without dominance by vocal participants. Questions often appear in the context of scope definition, requirements gathering, and stakeholder engagement.

Key Points to Remember (for the exam)

• Main Purpose: Structured group decision-making that prevents chaotic discussions and ensures equal participation from all members
• Key Differentiator: Participants provide input independently before group discussion, reducing groupthink and dominance effects
• Primary Use Case: Large groups dealing with controversial or complex topics where unbiased input is critical
• Core Process: Systematic gathering of input → discussion → voting/ranking → final decision
• Common Confusion: Not to be confused with brainstorming (unstructured idea generation) or Delphi technique (anonymous expert consensus via questionnaires)
• Exam Favorite: Questions where a project manager needs to prioritize requirements or resolve conflicting stakeholder opinions in a structured manner
• Output Quality: Produces prioritized, documented decisions that increase stakeholder buy-in and support

Typical PMI Exam Example

A project manager is facilitating a requirements prioritization session with 25 stakeholders who have conflicting opinions on feature importance. Several vocal stakeholders dominate the discussion. The project manager decides to use the nominal group technique to ensure all participants contribute equally and reach a structured decision.

PMI Exam Traps

• Trap: Confusing nominal group technique with brainstorming

• Reality: Brainstorming generates ideas without structure; nominal group technique systematically gathers and ranks input

• Trap: Thinking nominal group technique requires anonymous input like Delphi technique

• Reality: Nominal group technique involves face-to-face interaction; Delphi technique uses anonymous questionnaires

• Trap: Assuming nominal group technique is only for small groups

• Reality: The technique was specifically developed for large groups dealing with controversial topics

• Trap: Believing nominal group technique eliminates discussion entirely

• Reality: Discussion occurs after initial independent input collection; the structure prevents chaos
