There are several ways to do this. It's up to you which method suits you best. Here are a few options:
Fast approach:
The tour guide first completes the assessment and then invites the participants to add to it at certain points. This approach is particularly efficient.
Individual processing:
The tour guide invites all participants to work on the system independently. After a week, the team meets to review the results together and add to them.
Workshop format:
The tour leader organizes workshops, for example in the format "5 days to success". In each workshop, an element of the success assessment is addressed in the committee. The tour leader documents the team's views and contributions directly in the system. The workshop protocol automatically serves as the basis for the assessment.
