By now, you would be familiar with DMAIC methodology and know when, where and how it is used and the benefits of it in problem solving and performance improvement. But DMAIC is not the only methodology that is used in Six Sigma. There is another common term DMADV which is equally important as DMAIC. To become a master in Six Sigma and use it for business purposes, it is essential to be familiar with all the other methodologies. For that, we need to first understand where, when and why we use DMADV.
Similar to DMAIC, DMADV is another methodology that is used in organizations to achieve Six Sigma level of performance.
VOC: Voice of Customer; VOB: Voice of Business; VOP: Voice of Process; CTQ: Critical to Quality The steps DMA (expands as Define, Measure, Analyze) – are similar to DMAIC, (remember similar but not the same). The activities in DEFINE (Define the problem, Set up the goal) – is evidently the same as DMAIC. But in Measure and Analyze, there is a slight difference in what you measure and what and how you analyze. Finally, D & V stand for Design and Validate/Verify, respectively, clearly indicating that a Process Design is undertaken to meet Six Sigma levels of Performance. Hence, DMADV is alternatively also called as DFSS (Design for Six Sigma).
When is DMADV used?
DMAIC is used, when the problem you want to solve is for a process that is already existing but not meeting the expected levels of performance. DMAIC is used when you want to correct an existing process that has not been performing up to the expectations.
Alternatively, DMADV is used when you want to set up/design a whole new process, that should be meeting the desired level of performance from the beginning. DMADV may also be used when there is a need to redesign an existing product or process, rather than constantly correcting the process. The soul of DMADV is in understanding the customer’s requirements and the CTQs which are mostly expressed qualitatively.
