Promo Effectiveness on Snowflake, for supply chain
Ward reads any table or view in your Snowflake account, cross-database joins, historical data at any depth from Snowflake, runs promos on it, and hands back the supply chain read each day.
How a VP Supply Chain runs promos off Snowflake
You find out about stockouts after customers do. Ward pulls forward the readings that change a supply chain decision.
Here is promo effectiveness in plain terms. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
The mechanism. Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
Getting the data in. Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake.
What it does
- Cannibalization quantification
- Pull-forward detection
- Promo ROI scorecards
- Net lift measurement (not gross)

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 this combination
is its own problem.
A VP Supply Chain does not need the promos model explained. They need to know which stores moved, why, and what to do by end of day. Ward writes the finding at that altitude.
What Ward has eyes on.
Know which promos actually work. Ward runs the model continuously rather than on a reporting cycle, which is why a finding lands the morning the pattern starts instead of at the end of the period.
The connection to Snowflake is read-only and runs on your schedule. Ward pulls from any table or view in your Snowflake account, cross-database joins, and the rest of the feed, then cross-references it with external context your Data Platform does not carry: weather, local events, competitor pricing.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Snowflake. Ward ingests any table or view in your Snowflake account, cross-database joins, historical data at any depth and starts building baselines. First daily cards land inside 48 hours, before baselines are stable, so you can see the shape of the output early.
-
02
Weeks 2 to 3: baselines
Ward needs roughly two weeks of history per store to separate a real deviation from normal variance. During this window the cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward sends findings every morning, each with the cause and a recommended move. Volume settles at a level a single person can read over coffee. The measure of success is not how many insight cards arrive, it is how many get acted on.
