Reflecting on the different tools that can be used in Sustaining Improvement

After reading chapter 8, I think everyone can agree that we have at least used two of the tools mentioned. I found the Nominal Group Technique interesting. We do a lot of group work in Staff development but there is usually discussion. I can understand giving a rating to the issues but I didn't see how that would solve a problem. I felt that it could be used to put things in perspective by importance, which helps with prioritizing.
