A software guardrail is an enforced constraint or check that helps prevent unsafe operations, especially when investigating failures and deciding between system changes, retraining, or additional reviews. section 7.2.2
Choose guardrails by examining how the failure occurred:
- Separate mistakes caused by insufficient training from sophisticated edge cases that training could not reasonably prevent. section 7.2.2
- Check whether distraction, stress, or missed steps contributed to the unsafe operation. section 7.2.2
- Record the incident and document the corrective steps so safeguards address the actual failure mode. section 7.2.2
Wrong production window
A system manager deleted production web servers after mistaking a production terminal for a development terminal. A conspicuous color for production sessions became an immediate visual guardrail. section 7.2.2
