Start with the workflow, not the model

A model can perform well in isolation and still fail inside the operation. Inputs arrive incomplete, policies collide, user intent is ambiguous and the cost of a plausible answer varies by context.

Production framing begins with the decision being supported, the authority retained by people and the conditions under which the system must stop or fall back.

  • Bound the task and failure cost
  • Identify the accountable operator
  • Make fallback part of the primary design

Evaluation is an operating sensor

A benchmark is a starting point, not a control system. Representative evaluation sets, feedback from real work and production telemetry need to evolve together.

The objective is not a single accuracy number. It is visibility into where the workflow performs, where it degrades and whether operators can detect the difference.

  • Evaluate representative cases and edge conditions
  • Segment results by risk and task
  • Connect incidents back to the evaluation set

Someone must own change

Sources change, models change and policies change. Without an owner for the whole workflow, each improvement can create a new unobserved failure mode.

Operational ownership includes release criteria, incident response, source stewardship, user feedback and the authority to narrow or stop the capability.

Executive takeaways

  • Design the full decision workflow
  • Treat evaluation as continuous infrastructure
  • Keep human authority and fallback visible
  • Assign ownership before scale
