DMAIC or DMADV?
The popular acronyms of Six Sigma, DMAIC and DMADV may seem similar when compared. Not true say the experts and deciding which Six Sigma methodology to use can mean the success or failure of your projects. The only similarity between the two is they both use a non-intuition approach and stick to cold, hard facts.
The DMAIC should be used for processes or products within your own organization that manage deliverables to your clients. DMADV, on the other hand is best used if you have never implemented Six Sigma into your products or processes; or a Sig Sigma starting point.
So many project managers get confused on Six Sigma and through mere explanation, says Jim Parnella, it's easy to get the point across. Jim Parnella gives what he calls his 30-second "elevator speech" on Six Sigma often. "Six Sigma is a disciplined, data-driven approach to process improvement aimed at the near-elimination of defects from ever product, process and transaction. The purpose of Six Sigma is to gain breakthrough knowledge on how to improve processes to do things better, faster, and at a lower cost. It can be used to improve every facet of business, from production, to human resources, to order entry, to technical support. Six Sigma can be used for any activity that is concerned with cost, timeliness and quality of results. Unlike previous quality improvement efforts, Six Sigma is designed to provide tangible business results, cost savings that are directly traceable to the bottom line." Mr. Parnella's 30-second explanation of Six Sigma is by far the best I've come across.
If we use his explanation as a base, it's easy to identify which is best, DMAIC or DMADV?
