Nominal Group Technique, NGT
This method is useful whenever you need to quickly gather and synthesize input (facts, opinions, evaluations) from a group of people; especially useful when the group is part of an established hierarchy.
A critical point is the formulation of the starting question. Some examples:
✴ What are our criteria for success? What do we mean, when we look back at a piece of work and say that it was successful?
✴ What is functioning well and what is not functioning well in our current work/project?
✴ What factors might help us achieve our goals, and what might hinder us?
