The Moving Motivators facilitation exercise is based on the Champfrogs model of the ten intrinsic desires, which motivates us most. Jurgen Appelo, Management 3.0 guru, developed the game and derived the model from the works of Daniel Pink, Steven Reiss, and Edward Deci/Richard Ryan.
For sure, there a lot of psychological based theories of what motivates human best - all differing in slight details. The Champfrogs model is a best-of-breed approach out of all.
The Moving Motivators facilitation reveals the effect of an (organisational) change on the people's motivators. When most of the important motivators go down, or when only the least important ones go up, you may realize that you have some work to do on your own motivation.
For facilitation prepare one card set for each participant. The facilitator should ask the participants at the beginning to take notes of their own and of all other results.
The exercise may give better insights than a regular conversation.
