Operate the outcome, not just the model
A production service review begins with the accepted outcome, eligible population, baseline, target, adoption indicator, operating owner, metric owner, verifier, and attribution limits. Pair them with reliability, safety, latency, cost, human-review load, exception rate, and change history. Good model quality cannot compensate for non-adoption or negative economics.
Define service objectives that reflect user and business impact as well as infrastructure. Monitor the decision route: source availability, context quality, model behavior, tool behavior, human review, effect result, and source-of-truth readback. This makes it possible to localize failure without treating every incident as model drift.
