The improvement phase of DMAIC is easily the most fun; everyone gets to showcase their ideas. As I have said in other posts, be careful not to let any predetermined solutions into this phase. The data you have collected should tell you where the real problem is and allowing all participating parties to brainstorm should yield a solution.
Improvement is pretty simple. Just pick the best idea and move on. If possible, try the idea out and measure it again to ensure you can achieve the desired results before closing the project.
It is not uncommon for people to disagree concerning the correct path to take. This of course is much more of a problem in larger groups. With big teams, vote on improvement ideas before moving forward. This helps create buy-in and eliminates debate that wastes time. It may also help to vote anonymously. Try to avoid spending time talking and not doing. Have you ever witnessed someone spend all day making a report pretty without actually getting anything done? Talking during the improve phase of DMAIC is the same thing. You should spend your resources doing since the analyze phase should have pointed you in the correct direction.
Six Sigma, LEAN, DMAIC, or any other continuous improvement is not about being presentable, it is about hard measurable results.
Does anyone have any great examples?
