Thumballâ€¢Ã€_â€¢Ã€__â€¢Ã€_â€¢Ã€___ is a soft 6" stuffed ball pre-printed with 32 questions or prompts and LOADS of interesting applications for meetings, training, and employee relations. The Debriefing Thumball helps facilitators ask debriefing questions in a proper sequence that makes sense to participants. It can also shift some of the responsibility for successful processing from the facilitator to the participants. The sequence of 1. What happened, 2. Why is this important, and 3. How can I use this information, not only takes participants through a progression for processing a specific event, but also presents an overall lesson on proper processing.
