3×5 Why Analysis

This is a checkbox which, if enabled, allows users to apply the 5Ws to 3 types of causes/failures.

• If selected, it will add the three following fields to this section:
  1. Direct Cause
     • What was the DIRECT or specific cause of the problem? Explain why the problem occurred (e.g., design/drawing error, manufacturing process, assembly/installation instructions).
       
       • 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. Systematic 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?
