Reliability testing is critical for new component qualification, design change validation, or field failure simulation for root cause analysis. In many cases, with tight project schedules and scarce available resources, some important critical characteristics of a component or subsystem are overlooked. This will potentially result in new failure modes after implementing changes in production. The author will explain how to develop an effective test plan using the 6? (Six Sigma) problem solving process, IDOV (Identify, Design, Optimize and Validation), to make the testing simple but efficient.Learning Objectives:��Reliability testing is important tool used for the new design or new supplier evaluation and approval. It will save product development time when appropriate test plan is developed and executed. With more than 5 years reliability testing experiences, the author will share the lessons learned and strategies on how to develop the reliability test plan and conduct test result analysis to drive design improvement. The audience (reliability engineers or managers) shall be able to learn how to effectively prevent unknown failure mode while eliminating the well known failure modes by conducting proper reliability testing.
