Measurement is not only a buying tool. Once a workflow has ground truth, work can be routed to the best supplier case by case. Model and harness builders can improve against real enterprise failures. Insurers can price risk at the workflow level. Agent companies can certify capability against a defined body of work. These are continuous systems: every model release and agent update creates a reason to measure again, and every workflow that becomes automated exposes the next layer of work to map.
