Activities and Tools | Identify | Design | Analyze | Verify | Validate | Monitor and Control | |
Tasks | Define the reliability requirements and usage. | Prepare circuit layout, mechanical drawings, component/supplier selection. | Estimation of the product’s reliability and the potential source of product failure. | Prototype built for testing and more detailed analysis. | Functional and environment testing at the system level with the purpose of becoming production ready. | Ensuring that the process remains unchanged and that variations remain within tolerances. | |
Customer expectations and metrics. | |||||||
More specific reliability requirement is defined. | |||||||
Selection of methods and tools (Finite Element, Physics of failure, Reliability Block diagram, Engineering judgment, expert opinions, historical data, etc.). | Selection of methods and tools (Test to failure, degradation analysis, Reliability Growth Process, Design Review Based on Test results). | ||||||
Gap analysis and Benchmarking. | |||||||
Introduction of reliability risk methods and tools (Reliability Prediction, FMEA, FMECA, FTA, etc.). | If necessary to involve design improvements. Tools (Accelerated, Failure-Oriented Accelerated Testing techniques). | ||||||
