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.
DFSS and DMADV are Essentially the Same Methodology
- 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
