Users can select this checkbox to apply the 5Ws to 3 types of causes/failures.

     • What/Where/When/Who/Why: These are all text fields that allow users to input their answers. They can be expanded to encompass multiple lines.
2. Detection Cause
   • Why was the problem not DETECTED? How did it pass through to the customer? Explain why the problem was not detected by the quality/inspection system. (How did we have an escape?).
     
     • What/Where/When/Who/Why: These are all text fields that allow users to input their answers. They can be expanded to encompass multiple lines.
3. Systemic Cause
   • How did the SYSTEM contribute to the problem? Did any business processes fail? How was the problem introduced? Was there a failure or weakness in a process, procedure, work instruction, or standard?
