DFSS (Design for Six Sigma)

Methodology for designing new products, processes, or services to achieve Six Sigma performance from the start, rather than improving existing processes. Uses frameworks like DMADV (Define-Measure-Analyze-Design-Verify) or IDDOV (Identify-Define-Develop-Optimize-Verify). Emphasizes Voice of Customer, robust design, and built-in quality rather than inspection. More proactive than DMAIC which fixes existing problems. Requires different skill set focused on design trade-offs, simulation, and predictive analysis versus reactive problem-solving.
