Nominal Group Technique (NGT) minimises many problems associated with conventional interactive group problem solving; however, its verbal inputting feature is unnecessarily limiting. By utilising cards, the Improved Nominal Group Technique (INGT) assures contributor anonymity, adds productive pre‐meeting activity and removes NGT′s inputting‐transcribing bottleneck. INGT is appropriate for identifying and evaluating options, positions or problems, solving a problem, and for reviewing and refining written proposals or other documents.
