Standfirst. A human checkpoint is effective only when the reviewer sees the relevant evidence, understands the expected failure, has authority to stop the process and records a decision before the consequence occurs.
Place checkpoints at transitions
Map the workflow from input to action. Add a checkpoint when information enters a new trust boundary, an uncertain output becomes a professional conclusion, or an internal proposal becomes an external action. One approval at the end cannot reliably detect wrong inputs or actions already executed.
Design each checkpoint
For every gate, define:
- the object being checked;
- the authoritative evidence displayed;
- expected error types and alert thresholds;
- the authorised role and required competence;
- approve, correct, reject and escalate actions;
- the record retained and its purpose;
- the maximum queue time and safe timeout behaviour.
Avoid passive confirmation buttons. Present source citations, changed fields, confidence or reconciliation results, missing data and policy exceptions in a readable interface. Do not use colour as the only signal. Keyboard operation, clear focus and descriptive labels matter.
Checklist
| Question | Minimum answer |
|---|---|
| What can fail? | Named failure modes |
| Can the reviewer detect it? | Evidence visible at decision time |
| Can they stop it? | Execution technically separated |
| Who owns exceptions? | Named queue and escalation |
| What is recorded? | Version, evidence, person, outcome, time |
| How is performance tested? | False positives, false negatives, overrides, delay |
Monitor rubber-stamping, override rates, unresolved exceptions and reviewer disagreement. These can reveal poor interface design, inadequate training or a model operating outside its intended conditions.
Cytria’s operational interpretation
Human involvement is not itself a safeguard. The safeguard is a designed decision point where the right person can detect a specified failure using sufficient evidence before impact.
