概要	A citizens' jury is a deliberative method that convenes a small, demographically representative panel of randomly selected citizens to consider a policy question in depth and produce reasoned recommendations. Modelled loosely on the trial jury, it gives ordinary people time, balanced information, expert witnesses and skilled facilitation so they can deliberate and reach a considered judgement on behalf of the wider public. Developed in the United States by Ned Crosby and his Jefferson Center, with a parallel German tradition (the Planungszelle) created by Peter Dienel, it is a leading form of deliberative 'mini-public'.	The Nominal Group Technique (NGT) is a structured group facilitation method designed to generate and prioritise ideas, problems, or solutions while ensuring equal participation from all members. Developed by Delbecq and Van de Ven in 1971, it combines silent individual idea generation with structured group discussion and systematic voting to produce a ranked list of priorities. Unlike unstructured focus groups, NGT prevents dominant voices from suppressing quieter participants, making it especially valuable for needs assessment, program planning, and stakeholder priority-setting in applied research and policy contexts.
