Integrating Reliability and Durability Improvements with Six Sigma

Conventional tools of process Six Sigma (DMAIC) are frequently not adequate to measure and improve reliability. Moreover, reliability is predominantly a function of design. Design for Six Sigma (DFSS) process of Concept-Design-Optimize-Verify (CDOV) can therefore be a better strategy to improve reliability and life.

Warranty and overhaul data of complex products provides a very good starting point. Life data analysis of warranty failures provides input on reliability baseline performance. Similarly, the data of components/subsystems that have failed and survived till overhaul provide valuable inputs to estimate life. Both these analyses provide critical input for baseline data of current durability. Potential DFSS projects can be identified and prioritized using cause and effects matrix. Wherever possible, analysis software are useful to predict improvements. These can be validated with reliability tests, accelerated life testing (ALT), Multiple Environment Overstress Tests (MEOST).
