DMADV (Define, Measure, Analyze, Design, Verify) is often known as DFSS or Design for Six Sigma. Since Six Sigma uses many of the quality management implements well within the many different phases of DMADV, it is only natural that these same phases would work anywhere.
In order to understand DMADV (Define, Measure, Analyze, Design, Verify) one must look at and understand each of the five phases that it must go through. The first, of course, is design.
When worked within the confines of a DMADV project, the term define only means that goals are going to be made distinct. Depending on what consumers are demanding and needing, and what the business is willing to consider, the distinctions will vary. However, there will be some that will work for both and these need to be found for an idea and basic plan to be created.
When looking at the next term, measure, this is when things start to get a bit more technical. Not only are they going to measure the capabilities of a business to be able to produce the product, they are also going to measure the risks associated with taking the project on. They will identify what are commonly known as CTQ’s or which features are Critical to Quality.
When the Six Sigma team turns to the third phase, the analyze phase, they will then work on the design and several alternatives to that particular design and then evaluate each specific one to see if it is the best of all the designs they have created. These will all be of high level and only the best design that can create the specified product will continue to be considered.
From there, they go into the details. This is the stage where the chosen design is optimized for peak performance. They also create a verification process that will determine whether or not the product or service is feasible. Simulations can often be found in use during this stage.
Finally, they verify the design. This is far beyond simulations, as it is now time to actually do practice runs of the equipment and see if production is going to go as planned. Should all go well during this final stage, it is finally given to the owner to utilize.
Since DMADV is so often used by a Six Sigma team, it is considered a process that is necessary for them and even thought of as exclusively used by the methodology, although it can easily be used outside of a Six Sigma environment.
