Design For Six Sigma

Design for Six Sigma (DFSS) is the application of Six Sigma principles to the design of products and their manufacturing and support processes. Whereas Six Sigma by definition focuses on the production phase of a product, DFSS focuses on research, design, and development phases. DFSS combines many of the tools that are used to improve existing products or services and integrates the voice of the customer and simulation methods to predict new process and product performance.

DFSS can be compared to DMAIC (Design, Measure, Analyze, Improve, Control) and often the acronym DMADV (Define, Measure, Analyze, Design, Verify) is used to describe the strategy of DFSS. The precise phases or steps of a DFSS methodology are not universally defined. Most organizations will implement DFSS to suit their business, industry, and culture. DFSS methodology, instead of the DMAIC methodology, should be used when:

* A product or process is not in existence at your company and one needs to be developed
* The existing product or process exists and has been optimized (using either DMAIC or not) and still doesn't meet the level of customer specification or six sigma level
DFSS is a way to implement the Six Sigma methodology as early in the product or service life cycle as possible. It is a strategy toward extraordinary ROI by designing to meet customer needs and process capability. DFSS can produce the same order of magnitude in financial benefits as DMAIC. But it also greatly helps an organization innovate, exceed customer expectations, and become a market leader.
