Nominal group technique allows a team to quickly come to a consensus on the relative importance of issues, problems, or solutions by accounting for individual importance rankings in a team’s final priorities. This technique:
- Builds commitment to the team’s choice through equal participation in the process
- Allows every team member to rank issues without being pressured by others
- Puts quiet team members on an equal footing with more dominant members
- Makes a team’s consensus (or lack of it) visible; the major causes of disagreement can be discussed
|How to Use Nominal Group Technique|
1. Start a List
Generate the list of issues, problems, or solutions to be prioritized.
In a new team with members who are not accustomed to team participation, it may feel safer to do written, silent brainstorming, especially when dealing with sensitive topics.
2. Record Issues (Draft)
Write statements on a flipchart or board.
3. Clarify Issues
Eliminate duplicate and/or clarify meanings of any of the statements.
As a leader, always ask for the team's permission and guidance when changing statements.
4. Record Issues
Record the final list of statements on a flipchart or board. For example:
Why doesn't the public health system effectively assist local health jurisdictions with epidemiologic investigations (as described in national performance standards)?
Use letters rather than numbers to identify each statement, so that team members do not get confused by the ranking process that follows.
5. Rank Issues
Each team member records the corresponding letters on a piece of paper, and ranks the statements in order of importance. For example:
Sonya's sheet of paper looks like this:
This example uses "4" as the most important ranking and "1" as the least important. Since individual rankings will later be combined, this "reverse order" minimizes the effect of team members leaving some statements blank. Therefore, a blank (value = 0) would not, in effect, increase its importance.
6. Combine Rankings
Combine the rankings of all team members. For example:
One-Half Plus One
When dealing with a large number of choices, it may be necessary to limit the amount of items ranked. The “one half plus one” approach would rank only a portion of the total.
For example, if 20 ideas were generated, then team members would rank only the top 11 choices. If needed, this process could be repeated with the remaining 9 items, ranking the top 5 or 6 items, until a manageable number are identified.
Each team member rates, not ranks, the relative importance of choices by distributing a value (e.g. 100 points), across the options. Each team member can distribute this value among as many or as few choices as desired.
