A practical evaluation loop for applied AI products

Applied AI becomes useful when a team can explain what better looks like, which errors matter, and how the workflow behaves when confidence is insufficient. A model demonstration is only the beginning of that work.

Start with the decision

Define the person making the decision, the information available to them, the current cost of the workflow, and the consequence of a wrong answer. This keeps evaluation connected to a real outcome rather than a generic model score.

Build a representative case set

Good cases include routine work, ambiguous inputs, missing context, adversarial behavior, and high-consequence exceptions. Review them with the people who understand the domain and record why an answer is useful or unsafe.

Operate the evaluation

Run the case set when prompts, models, retrieval, tools, or policies change. Pair automated measures with targeted human review, and feed production failures back into the set so evaluation improves with the product.
