Promo Effectiveness on Power BI, for merchandising
Ward pulls from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs from Microsoft Power BI, runs promos on it, and hands back the merchandising read daily.
How a VP Merchandising runs promos off Microsoft Power BI
Your category managers are drowning in spreadsheets. Ward filters to what a VP Merchandising can act on and drops the rest.
Promo Effectiveness, in one sentence. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
What Ward does with that: Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
How the connection works. Ward connects to the same data sources Power BI uses. Or reads Power BI datasets via REST API. Your reports stay untouched.
The short list
- Net lift measurement (not gross)
- Cannibalization quantification
- Pull-forward detection
- Promo ROI scorecards

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.

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.
Ward pulls from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs from Microsoft Power BI on a read-only connection. Nothing is written back, and your BI configuration does not change. Power BI stays the system of record.
Why this combination
is its own problem.
Promo Effectiveness needs power BI REST API datasets and underlying SQL/Azure data at minimum. Microsoft Power BI carries both, at the grain the model needs. That is the whole integration story: no middleware, no staging warehouse, no custom extract.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Microsoft Power BI. Ward pulls from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs and starts building baselines. First 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 cards daily, each with the 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 insight cards arrive, it is how many get acted on.

Your category managers are drowning in spreadsheets.
- ×Promo planning still runs off last year's playbook
- ×Assortment reviews happen quarterly when they should happen daily
- ×Price changes chase the market a week behind it
- ×No visibility into true cannibalization across categories
- ×Vendor negotiations lack real-time sell-through evidence
- ✓Insight cards flag promo cannibalization the day it happens
- ✓Assortment gaps and whitespace opportunities surface automatically
- ✓Price elasticity shifts detected before margin erosion compounds
- ✓Category-level performance cards replace manual spreadsheet reviews
- ✓Vendor scorecards generated from actual fill rate and quality data
