Out of Matrix, Still in Stock: Assortment Matrix Control for Multi-Store Retailers
A delisted SKU leaves the matrix in one click, but its leftover units can sit in your stores for months. In chains with 20+ stores, one assortment decision passes through six handoffs – store scope, planogram, replenishment, sell-down, follow-up – and margin leaks at every gap. This guide for category managers follows that decision from the matrix to the last unit in the store, shows the four places where margin goes, and gives you a check for each one you can run this week from reports you already have. Inside: the MasterZoo case (200+ stores, 6,000 active SKUs) and a 90-day plan.
A practical guide for category managers in multi-store chains who want every delisting, new listing and store exception in the assortment matrix to reach the shelf and the order – not stay in a spreadsheet.
