The certified fulfillment-performance metric for the 3PL warehousing domain. One row per (ship_month × client_segment × site_region × temp_class × carrier) carrying raw COUNT columns — `order_count`, `units_shipped`, `otif_count`, `on_time_count`, `in_full_count` — never pre-divided rates. `ship_month` is `toStartOfMonth(ship_date)` over shipped orders only, so it is a trend surface and the counts are correct denominators for on-time / OTIF rates. The metric layer exposes `otif_rate` / `on_time_rate` / `in_full_rate` as FORMULA measures (count / nullif(sum(order_count), 0)) so multi-bucket roll-ups recompute correctly rather than averaging pre-averaged percentages. Nullable dims are coalesced to `unknown` upstream so they stay visible rather than dropped.
- highTreating a count measure as a rate
`otif_count` / `on_time_count` / `in_full_count` are counts, not rates. Request the `otif_rate` / `on_time_rate` / `in_full_rate` formula measures — the metric layer divides by `order_count` with `nullif` window-correctly. Reading a count as a rate is a category error.
- mediumReading a single month as the full-period rate
The grain is keyed on `ship_month`. Sum the counts across the relevant month range and let the formula measure divide — dividing per-month pre-aggregated outputs client-side is an average-of-averages, biased across buckets of unequal size.
- mediumComparing carriers blind to temp class
Carrier on-time performance varies structurally by `temp_class` (frozen vs ambient lanes differ). Slice by `temp_class` before ranking carriers, or a mix-shift will distort the comparison.
- “What was OTIF for life_sciences clients in the EU last quarter?”
- “Which carrier has the best on-time rate for frozen goods?”
- “How does in-full rate trend by temp class this year?”
- pick_accuracy
Fed by the same `mart_fulfillment_daily` rollup — pairs delivery performance (OTIF / on-time / in-full) with picking quality (accurate lines / total lines) for the same buckets.
- returns_rate
Uses this metric's shipped-order count as the denominator for the return rate — pair to read fulfillment quality against downstream returns.
