DFSS - Design for Six Sigma

QI Macros DFSS Tools Can Help You Design New Products and Services

Go Deeper: 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

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