What is the difference between the two methodologies DMAIC & DMADV and its application in different industries/org

The DMAIC methodology, instead of the DMADV methodology, should be used when a product or process is in existence at your company but is not meeting customer specification or is not performing adequately.

 

The DMADV methodology, instead of the DMAIC methodology, should be used when:

• A product or process is not in existence at your company and one needs to be developed
• The existing product or process exists and has been optimized (using either DMAIC or not) and still does not meet the level of customer specification or Six Sigma level.

Hi Ram, 

 

I agree with your answer in general but not with the final section. Kindly note that reaching six sigma level is not the goal. For some processes, 3 sigma is good enough and for some others 7 sigma is insufficient. The idea is to reach a sustainable performance level that makes enough business sense. Both DMAIC and DMADV aim at this.
