IMPROVED NOMINAL GROUP TECHNIQUE (INGT)

PHASE
Idea generation
DESCRIPTION

Improved Nominal Group Technique is a extension of Nominal Group Technique (NGT) with an additional pre-meeting stage which ensures full anonymity of contributions and speeds up transcription phases.

Advance Preparation

  1. Clarify the purpose of meeting with a prior problem recognition meeting, with anonymous input
  2. Circulate the agreed purpose of the meeting and request anonymously submitted ideas on cards by a well-defined cut off time.
  3. Circulate a numbered word for word list of the ideas submitted and request those participating bring to the meeting any additional ideas (on cards) or proposals for varying or combining ideas. Explain fully what structure the meeting have.

The Meeting

  1. Explain how the meeting will proceed and ensure all participants have a pre-circulated list of ideas
  2. Collect anonymously any further ideas brought to the meeting and add to existing set. Place all cards face down (those with no ideas submitting a blank card) and shuffle. List all ideas on a Flip Chart.
  3. Participants write yet more ideas privately, again on cards. Adaptation or amalgamated of items may be proposed, but only permitted if all agree – no discussion.
  4. Every few minutes, the leader gathers ideas anonymously and lists them as described earlier. Writing continues whilst the leader records the information from the cards onto the Flip chart. Repetition of the writing/gathering rotation is maintained pending all the gathered cards being blank
  5. Go through the full list of items, inviting observations on each one within agreed time limits. Participants may consider giving an explanation, or present a view for or against any item, however debating is not permitted. Authorship remains anonymous and rules for adaptation or amalgamation of items as per step 3 above continue throughout. Addition of items suggested by the discussion is acceptable.
  6. Private voting takes place and participants list on a card the item numbers of their top X items and ranks them in preferential order. If you are trying to identify problems, X can be larger (e.g. 15% of the number of items). If you are trying to discover a solution it could be smaller (e.g. 3-5 items).

Votes are tallied on a Flip chart once the cards are returned face down and shuffled. Further categorisation and voting may be needed, depending on circumstances.
