How does a store manager present out-of-stocks to regional management?
In shortThe presentation that works fits in five points and one page: the cost of out-of-stocks in lost sales (not as a rate), the split between store causes and upstream causes (with the real warehouse service level measured at receiving), the twenty SKUs that concentrate the loss, the three actions under way with their measured result, and one precise request (a replenishment pass, a receiving check, a warehouse parameter fix). A store manager who presents £4,000 a week, £1,500 of it attributable to the warehouse, with figures to back it, gets an answer; a store manager who presents 6% only gets a comparison with the store next door.
What regional management hears
An out-of-stock rate of 6% calls for one reaction only: comparison with the other stores. If the regional average is 6, the subject is closed; if it is 5, the store manager leaves with an instruction and no resources. In both cases nothing changes in the store.
A useful presentation moves the conversation from the rate to the cost and the causes. It relies on the same indicators as weekly steering (out-of-stock dashboard: which indicators to track every week), converted for a reader who has ten minutes.
The page in five points
1. The cost, in money
Estimated lost sales for the month, calculated SKU by SKU (hourly sales × duration × 55% really lost, from the reactions measured by Gruen, Corsten and Bharadwaj). The method is in how to measure sales lost to out-of-stocks. Recall the national order of magnitude: in the UK, the Retail Economics and DHL audit puts on-shelf availability at 89.7% and finds an out-of-stock item in one grocery trip in five.
2. The split of causes
Two columns: what depends on the store (replenishment, facing, book stock, local ordering) and what depends on upstream (incomplete deliveries, delays, SKUs out of stock at the warehouse). The reference is 72% in store according to Corsten and Gruen; what matters is the store’s gap from that reference, measured with checking by SKU at receiving (receiving and checking by SKU) and the real service level (supplier service level and out-of-stock rate).
3. The twenty SKUs that concentrate the loss
A short table: SKU, out-of-stocks in the month, lost sales, identified cause. This is the table regional management remembers, because it is concrete and often contains warehouse out-of-stocks they can escalate.
4. The three actions under way and their result
Three, not ten, with a before and an after figure:
| Action | Before | After | Time |
|---|---|---|---|
| 5 pm replenishment pass on fresh and grocery | 11% out of stock at 6 pm | 5% | 6 weeks |
| Cycle counting on 50 SKUs | 21 wrong stocks out of 200 counted | 12 | 2 months |
| Checking promo pallets by SKU | 22 promo SKUs out of stock before Thursday | 7 | 1 operation |
Measured results give credibility to the request that follows.
5. The request
One precise, costed request that regional management has the power to grant: a warehouse parameter fix on identified SKUs, a second weekly delivery on fresh, arbitration of a recurring supplier dispute, or two extra hours a day whose cost is set against lost sales.
What to avoid
- Presenting the announced warehouse service level as if it were the received service level: it is almost always higher.
- Mixing stock-outs and shelf out-of-stocks: management hears “the store did not order” when the product is in the back room (stock-out or shelf out-of-stock).
- Asking for a tool before showing the actions: the tool comes after the proof that the store knows how to act.
- A twenty-page deck: one page, and the twenty-SKU table as an appendix.
A worked example (hypothetical)
Take a fictional case. Manager of a 2,200 m² supermarket, quarterly review. Page presented: £3,800 of lost sales per week, 68% store causes, 32% upstream causes including £1,200 on six SKUs recurrently out of stock at the warehouse. Three actions presented with results. Request: treatment of the six SKUs by regional supply. Answer obtained within the month, and the six SKUs leave the top 20 the following quarter. The figures are illustrative.
What shopper reporting changes
With ShelfAlert, the five points of the page come out of the dashboard: shopper reports give the SKUs, times and durations, crossed with book stock for the split of causes. The quarterly page is prepared in half an hour, and regional management sees the same table for every equipped store. 14-day trial, no payment card: see the plan for store managers.
