Six Sigma Certification

Define, Measure, Analyze, Design, and Verify: DMADV or DFSS  

The DMADV is one of the two elements of the Six Sigma methodology, the other element being DMAIC or Define, Measure, Analyze, Improve, and Control. This facet of the implementation of the concept of Six Sigma is part of the training instilled on the black belts to help them earn a six sigma certification.

DMADV, or Define, Measure, Analyze, Design, and Verify, is also known as DFFS, or Design for Six Sigma. This is inspired by W. Edwards Deming’s Plan-Do-Check-Act Cycle, along with the DMAIC. If DMAIC aims to improve a business process, DMADV seeks to establish a new product or design. All these two methodologies are important to help earn a six sigma certification.

The first step is to define. It has its similarities with the first step in DMAIC by concentrating on the demands of the customer and of the specific goals of the company, but it aims to define a certain goal for a desired design or product.

The second step is to measure. Things that needed to be measured are the critical to qualities or the CTQ’s, capability of the process production, assessing the risks, and the capability of the product. The third step is to analyze. Providing analysis is essential to the development of the design and possible alternatives for the desired design.

The fourth step is giving the details of the design. Upgrading a prototype design is important to function properly. The fifth step is side-by-side with the fourth, and it is verifying. Pilot runs are done to verify if the design or product is effective, and if it is so, it is ready to be produced fully.

All of these steps are to be made in order to guarantee a full production of the product, and while production is on its way, DMADV can then be implemented to ensure that defects are detected and eliminated. Trainees are taught with this kind of methodology, and full knowledge of this and DMADV is grounds for a six sigma certification for a black belt.
