Design for Six Sigma (DFSS) and Reliability

This article is attempting to address the issues of reliability and design for six sigma. Specifically, it starts out with an overview of the DMAIC model, summarizes the DCOV model which is the prevention model of the six sigma approach and then progressively addresses the issues of reliability. The issues addressed here are: 1) concepts and time categories 2) specific issues of DFSS and reliability 3) characteristics of reliability and DFSS 4) approaches of using reliability 5) concerns about six sigma and 7) consequences and closing remarks.
