Nominal Group Technique (NGT) is a structured process for gathering knowledge from groups. The NGT has proven particularly effective and efficient for assessments of organic farming and other agri-environmental policies. These assessments typically consider impacts on a wide range of often conflicting objectives including economic, social and environmental objectives; often in situations were an incomplete knowledge base prevents an evidence–based assessment. The NGT process acquires knowledge in a manner that enhances group dynam-ics and limits the effect of dominant individuals.
