Process and design FMEA identifies and evaluates the potential failures of a process, product, or service. How is the risk priority number calculated?
  1. By assessing the impact of the failure mode, with 1 representing the least safety concern and 10 representing the most dangerous safety concern.
  2. By assessing the RPN, which is severity x occurrence x detection.
  3. By assessing the chance of a failure happening, with 1 representing the lowest occurrence and 10 representing the highest occurrence.
  4. By assessing the chance of a failure being detected, with 1 representing the highest chance of detection and 10 representing the lowest chance of detection.
Explanation
Answer: B - The risk priority number is calculated by RPN= severity X occurrence X detection. Any RPN value exceeding 80 requires a corrective action. Severity assesses the impact of the failure mode, with 1 representing the least safety concern and 10 representing the most dangerous safety concern. Occurrence assesses the chance of a failure happening, with 1 representing the lowest occurrence and 10 representing the highest occurrence. Detection assesses the chance of a failure being detected, with 1 representing the highest chance of detection and 10 representing the lowest chance of detection.
