25: Design Review/Verification Issue
Definition/Typical Issues
Was there a problem with the design review/verification process? Was a design review/verification not performed? Did the review/verification process fail to detect a problem in the design?
Note 1: This node includes normal design reviews. Hazard reviews, pre-startup safety reviews, change control reviews, and other risk identification methods are addressed by the Hazard/Defect Identification and Analysis Issue (#94) node.
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
- The design review process was supposed to verify that the design outputs were consistent with the design inputs. However, the design review failed to identify multiple discrepancies. As a result, inappropriate equipment was installed.
Typical Recommendations
- Ensure that design personnel present a summary of their design review process to a design review board.
- Develop an independent review process to be used during the design process to help ensure that the output requirements are consistent.
- Develop an independent review process during design to help ensure that calculations and analyses are correct and complete.
- Ensure that the design review process is documented.
- Provide qualified individuals to perform design reviews.
