DFSS - Design for Six Sigma

Use DFSS to Design New Products and Services

DFSS is the step-by-step method for designing and developing new products or services with at least a 4-Sigma performance.

Determine customer needs using Voice of the Customer (VOC)
Translate customer needs into product and process requirements using Design of Experiments (DOE)
Mistake-proof the process using Failure Modes and Effects Analysis (FMEA)
Design and test the process using DOE and Critical to Quality Measures (CTQs)
Develop a Control Plan for monitoring ongoing performance
