A.4:2 - Problem
| Failure | Practical consequence |
|---|
| A design account is treated as the actual System. | Editing the account appears to improve a System whose operation has not changed. |
| An operating result is compared with an unspecified target or under different conditions. | A reported pass or failure cannot guide the receiving decision. |
| A discrepancy automatically triggers design revision. | A still-applicable target may be weakened merely to make the discrepancy disappear. |
| Measurement, its record and target change are conflated. | A new observation is mistaken for a changed subject or a new System. |
