Plain-language summary
Human in the loop describes a workflow in which an accountable person reviews, changes, approves, or rejects a system output. The human needs enough evidence, context, and authority to make that control meaningful.
Why it matters
Human review creates a control boundary for material marketing actions. It allows business context, brand constraints, legal obligations, and operational capacity to be considered before a recommendation changes a live system.
How it works
The system presents the proposed action, supporting evidence, uncertainty, affected scope, and required permissions. A named reviewer can approve, edit, reject, or request more evidence, and the decision is recorded.
Key components
- Reviewable output
- Named authority
- Evidence and uncertainty
- Explicit action
- Audit record
Practical example
An assistant proposes moving budget between campaigns. A marketer checks margin, inventory, attribution limits, and campaign learning status before approving a smaller reversible change.
Common confusion
A person clicking a generic confirmation button is not meaningful oversight. The reviewer needs enough information, time, and authority to challenge the proposal.
Limitations and context
Human review can become ceremonial when the interface hides uncertainty or when reviewers are overloaded. High-risk actions may require separation of duties or more than one approval.
