One example of a training exercise was called Carousel Brainstorming. Trainees are divided into equal numbers of teams. Each team goes to one poster and lists as many responses to the question as time allows. Trainers need to specify if they want free thinking responses or quality responses. After a set time, teams rotate one station to the right or left and add onto the responses.
Teams rotate every five minutes until all teams have responded to all posters.
One member from each team then reports on the ideas generated.
