Human-in-the-loop is an operating design choice

Adding a person to every step destroys the benefit of automation. Removing people from every step creates risk. The goal is to place human authority where uncertainty or impact justifies it.

High-impact decisions
Ambiguous exceptions
Sensitive customer interactions
Final approvals

Use thresholds, not vague oversight

“A human checks it” is not a control. The workflow should define when review is triggered and what the reviewer is allowed to decide.

Risk categories
Exception types
Approval rules
