The sales record with a smaller profit
A fictional footwear company celebrates its biggest dispatch week. Finance reports that profit fell. Sales blames leather prices. Production points to a wholesale promotion. Each team is comparing a different period and neither can explain the full movement.
What the analyst checked
Reconcile the reported profit first. Then hold style and period constant as you compare realised price, variable cost and volumes. A shift towards a lower-margin line can reduce the average margin even if no individual product became less profitable.
The next decision
Prioritise the driver that accounts for the largest verified loss. If scrap explains most of the decline, test a yield fix on comparable orders. If discounts explain it, inspect whether promotion-driven volume actually covered the lost contribution.
