IDOV Overview

Design for Six Sigma (DFSS) focuses on the development of a new process, product or service. The focus is aimed at building six sigma quality in the system right from the start when cost is lowest. Compared to traditional design methods, DFSS often requires a longer product planning time in order to identify the critical to quality factors. However, by making sure requirements are accurately captured and translated into the design, there is an overall reduction in development time and design. IDOV is a common methodology used in DFSS.
