What happens if you are out of ideas of what or how to improve?
Not surprisingly this has been considered by some of the pioneers of Quality Assurance. They understood that there was a limit to the number of ideas a person could generate. The recommendation was to change the composition of the group coming up with the solutions while retaining continuity. One recommendation was to change everyone except the group note-taker. There is nothing to prevent people coming back in a few years with new solutions to new problems (or suggesting them to the new group once they have had a chance to recharge). Giving a break can work wonders for creativity.
