# [Product or feature]: how well it works · [Date] ## What it's for [Intended use, in one sentence] ## What it isn't for [Uses we don't support or recommend] ## How we tested it - Eval set: [description, size n, how built] - Production data: [period, number of cases] - Offline eval and production results are labeled separately below. ## How it performs | Measure | Result | 95% interval | n | Offline or production | |---|---|---|---|---| | | | | | | ## By segment | Segment | Result | Interval | n | |---|---|---|---| | | | | | ## Known failure modes | Failure | How often (with range) | What the product does when it happens | Fix status | |---|---|---|---| | | | | | ## Representative examples Two successes and two failures, chosen to be typical rather than best. ## Wording rules on this slide No single number without its range and n. No improvement claimed that is smaller than the interval. No "understands," "knows" or "thinks."
