Introduction
Nominal Group Technique is a structured group brainstorming process involving problem identification, solution generation, and decision making. It is particularly useful around defining consensus among members of a team/group regarding priority or importance of items on a brainstormed list.
It is used to build commitment to the team’s choice through equal participation from members.
Other uses include:
- To allow every team member to rank issues without being pressured by others.
- To give all members an equal voice.
- To easily see the teams' consensus (or lack of it).
- To ease into a controversial subject.
Materials You'll Need:
- Sticky notes or index cards & tape
- Markers, for writing
- Large surface area (work table, flip chart, white board, blank wall)
- Team members from all areas of the organization involved in the process
How To Use Nominal Group Technique
Introduction and Explanation
The Facilitator presents the problem in written form and reads it to the group. The group is given a chance to ask questions to clarify the statement so that all are in agreement.
Silent Generation of Ideas
Team members write as many ideas on separate sticky notes or cards individually. Often this section is timed (5 to 10 minutes).
Sharing Ideas
Through a "round robin" style, each member reads aloud one of his/her statements.
- The facilitator records it for everyone to see.
- There is no debate or discussion at this point.
- Each idea is presented once. There is no need to repeat an idea.
- This session continues until all members have stated their ideas and the team is comfortable with moving on. It may be necessary to agree on a length of time for this section.
Group Discussion
The facilitator asks for discussion on each recorded idea. Team members are to ask for explanation or clarification of any ideas listed.
- The group may suggest new items for discussion or combine items into categories.
- No ideas should be eliminated unless unanimously agreed upon by the group.
Record
Record the final list of statements for all to see. Each item is assigned a letter (A, B, C, D, etc.).
Silent Ranking and Voting
Team members rank the ideas based on their point of view.
- Each team member selects the top five ideas they think are most effective and writes them on separate index cards.
- They then rank each idea from five to one with five being the most important, four being the next most important and so on.
Vote Collection and Tallying
The facilitator collects the cards and tallies the votes.
Removal of Topics
Items that receive one or no votes are removed from the list.
Prioritizing Items Based on Total Point Values
Items with the highest total point values are the most important to the group and should be addressed first.
One Half Plus Rule
When there are a large number of choices, limit the number of items ranked using the "one half plus one" approach.
Example:
Why does the department have inconsistent output?



If twenty ideas were generated, then team members would rank only the top eleven choices (half of 20 = 10 +1 = 11). This process would be repeated with the remaining nine items, ranking the top five or six items (half of nine = 4.5 +1 = 5.5) until a manageable number is identified.
