Scenario planning is almost always done as a group exercise, with the group ranging anywhere from 9 or10 up to perhaps 30 participants. One facilitator can handle a group of about a dozen: after that , it’s advisable to have additional facilitators, as the process works best by breaking the group into smaller working teams for certain steps. Each team ought to have somebody hovering nearby to coach them.
Choosing the actual participants is an important task needing some real consideration. If the scenario planning is to have the greatest potential value,then the people who help create the scenario should be open, intelligent,motivated,imaginative and strategic thinkers.
