The Nominal Group Technique is a proven method for polling the opinions of groups while effectively managing the group dynamics.  The process creates tension while limiting the effects of members seen has having more political power.  The process also produces data that can be weighted and analyzed to determine the level of importance and criticality of tasks and behaviors.  You will receive a workbook containing the slides and rules and a toolkit containing instructions on how to conduct a Delphi, Focus Group, and the NGT and how to evaluate the data.  

This webinar is part of the six-part miniseries on data gathering methods.  Other topics include Observational & Cognitive Interviews, Critical-Incident Interviews, Sociograms, Surveys, and Flanders Interaction Analysis.
