Human-in-the-loop

Human-in-the-loop is a design where a person reviews, corrects or approves an AI system's work at defined points before it takes effect.

It lets a business use AI on work where errors are costly while keeping accountability with a named person. The design question is where to place the checkpoints: approving every item slows the process, while approving nothing moves risk onto customers and records.

For example, an accounts payable workflow might process matched invoices automatically but send any invoice above a set amount, or from a new supplier, to a controller for approval. The misconception is that a review step is enough on its own. Reviewers need the right context on screen and a manageable volume, or approval becomes a reflex rather than a real check.
