The market is becoming more competitive nowadays. Companies like General Electric, Honeywell, Raytheon and IBM have managed to save billions of dollars in cost savings by process and quality improvement through Six Sigma. The majority of companies like to implement DMAIC methodology because they have existing processes. The remaining minority of Six Sigma practitioners is using a Design for Six Sigma (DFSS) approach to design a new product. DMAIC mainly focuses to improve the existing processes in such a way that final products can be produced with extremely low defects i.e. 3.4 defects in 1 million opportunities. Design for Six Sigma on the other hand, is about the design, development and commercialization of new products and processes for Six Sigma quality.
