3 | Choose topic for evaluation of failure modes prior to its implementation | Analyse underlying cause on occurrence of a failure through a series of ‘WHY’ questions |
4 | ‘Contributory factors’ for potential failure modes are its implementation. | Causes of problems are investigated what went wrong? |
5 | Goal: Evaluate impact of changes and decrease the ‘RPN’ | Goal: Preventing recurrence of problem |
6 | Includes detestability in evaluation | Develop ways to defect and fix a problem. |
