26: No Review/Verification
Definition/Typical Issues
Was there a failure to perform a design/review verification?
Examples
Example 1
- The controls for a paper cutting machine were inconsistent with those of the other machines in the facility. A comparison between the control systems was to be performed as part of the design review, but the design review was never performed. As a result, an operator was killed when another operator mis-operated the controls.
Example 2
- A new conveyor system design contained three key design errors. No design review was performed, and the errors were carried through to the final installed system. The conveyor subsequently failed in service.
Typical Recommendations
- Identify the equipment and processes that require design reviews and verification.
- Use the list of equipment and processes that require independent verification and review to develop a schedule for the reviews.
- Ensure that design reviews are performed as scheduled.
- Ensure that design reviews are documented.
- Ensure that design personnel present a summary of their design review process to a design review board.
