In this video, learn how to identify the steps, tools, and deliverables of the Improve phase in a DMAIC project.
- Now that you know which key X's drive the performance of Y…you will want to develop and implement solutions…to address the key X's in order to improve Y.…You are now in the improve phase.…Remember, the main steps are, first,…generate potential solutions to address proven key X's.…Next, evaluate solution alternatives.…Then, select the right set of solutions to optimize Y.…Last, pilot and implement.…
Now, before implementing any solutions,…you must apply these tools and techniques.…New process maps to achieve a common understanding…of the improved process.…FMEA, or failure modes and effects analysis…to mitigate any potential risk of failure…and improve process.…Also, mistake proofing to prevent any possibility of errors.…And pilot testing to make sure it works…before full implementation.…Various tools such as DOE and process simulation may be used…to determine optimal settings.…
Check out my course, Six Sigma: Green Belt Training…for an introduction to DOE.…Here, in this Black Belt training,…you'll have the opportunity to design…
