I pulled Store 37’s last 28 days against the chain baseline. Two root causes, both compounding.
| Signal | Finding |
|---|---|
labor_efficiency | Rev/labor-hour −22% vs. cluster, staffing mismatch at 11a–1p peak |
inventory.fresh | Fresh fill 83%, backroom replenishment lag at 2–4p |
promo.lift | BOGO crackers cannibalized Brand Y by 28%, net category +6% |
Recommend: re-baseline Store 37 schedule against true peak, raise replen window to 1p, and review the BOGO before next cycle.

Why Stockout matters for Grocery retail
Grocery stockouts train customers to switch stores, not brands, and perishable supply chains leave almost no margin for error. Ward models sell-through velocity at the store-SKU-hour level, factoring in day-of-week seasonality, weather, and supplier lead-time variability to flag gaps before they materialize.
What Ward has eyes on.
Ward reads straight from Snowflake rather than replacing it. Any table or view in your Snowflake account, cross-database joins, historical data at any depth come across on a read-only connection, get enriched with contextual data, and come back as cards. Your Data Platform is untouched.
The stockout model runs each day, not on a reporting calendar. It flags the pattern, attributes what caused it, and attaches the next step before the number reaches a review deck.
Coverage is store by store, category by category. Ward monitors fill rate, shrinkage %, fresh waste % throughout 30,000+ SKUs and compares each store against its own baseline, not against the chain. That is the difference between knowing the estate is fine and knowing which seven stores are not.
At the metric level. Critical metrics: sell-through velocity by daypart, DC-to-store lead time variance, supplier OTIF rates, and substitution elasticity. Ward tracks all four because a replenishment overreaction creates waste that compounds the original stockout cost.
Why this combination
is its own problem.
A generic stockout model applied to a grocery footprint produces alerts nobody trusts. The thresholds are wrong, because grocery baselines are wrong for it. Ward learns the baseline from your own stores instead of importing one.
- 01 DSD vendors operate outside the WMS, so milk and bread stockouts never show up in the daily exception report.
- 02 Flat case-pack sizing across stores ignores 5x velocity differences between urban flagships and suburban locations.
Benchmarks. Healthy grocery on-shelf availability runs 95-98% by department, with fresh dipping to 88-92% in the closing daypart. A single percentage point drop on top-50 SKUs typically maps to 0.3-0.5% revenue erosion; the same drop on milk or eggs is closer to 0.8% because basket abandonment compounds.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward sits on top of Snowflake with read-only credentials and begins ingesting any table or view in your Snowflake account and cross-database joins. No config changes on your side. First insight cards arrive in two days.
-
02
Weeks 2 to 3: calibration
Baselines stabilize per store and per category. Ward stops flagging normal variance and starts flagging exceptions. This is the window where the false positive rate drops sharply.
-
03
Weeks 4 to 12: steady state
Ward delivers findings on a daily cycle, each with root cause and what to do about it. Volume settles at a level a single person can read over coffee. The measure of success is not how many daily cards arrive, it is how many get acted on.
