Even though the DFSS and original Six Sigma sound like similar terms, there are several differences between them. The Design for Six Sigma (DFSS) module is more end user based than Six Sigma, because Six Sigma aims to get rid of variability and incapability in the system and cares more about internal issues in the business. However, DFSS captures the wide perspective of market. Although it is stated in many sources that DFSS is product based, I don’t agree that it is simply product based because products are purchased by customers and they should be designed with respect to customers’ desires and beliefs, just as how we were taught in our Creating Busıness Excellence course. Paul Roberts wrote in class: “product and customer” on the board, and asked which one king is. Then he said that CUSTOMER is the KING! Customers have a free will and they can buy whatever they want, though the product is foolish! Even your product may be the most qualified product ever on the market or the most innovated, in some cases it doesn’t work!
However, DFSS catches and interprets customer feedbacks or thoughts, and then produces a new product according to the design X approach. Design for reliability, and maintainability are the subgroups of designX.
Lastly, I am enthusiastic about PEUSS and glad to have 1 week break :) Now we should read and prepare for the lecture week!
