Design for Six Sigma
|
|
Design for six sigma (DFSS) is a process used in the development of new products or services to ensure that they can be manufactured, or can operate, at Six Sigma levels. The core of the process is understanding the customer requirements. This is achieved by using a number of tools such as the "house of quality". Other statistical tools, similar to those used in traditional six sigma processes, are used to ensure that the product is designed in a way that satisfies the customer's requirements with few (i.e. six sigma) defects.

iSixSigma Magazine (http://www.isixsigma-magazine.com/) (Jul/Aug 2005) research documented the median value of hard financial benefits from a Six Sigma DFSS (one methodology under the umbrella of DFSS is DMADV) project (across all industries and company sizes) to be $200,000. Companies with less than $100 million in revenue see dollar results about 75% less, where as companies with revenue of more than $1 billion see dollar results more than 100% higher.
