CORE DEFINITION
A stock keeping unit is the unique identifier assigned to each item that is tracked, priced, and counted separately. Purchasing, sales, inventory, and replenishment all key off that code, making it the base granularity of retail and supply chain data. The choice of granularity matters directly: splitting by colour and size raises analytical precision but also administrative cost, while coarser codes are cheaper to run but blur the analysis. It is distinct from a barcode, which is a carrier, and from a product-level identifier.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use granularity decision: choose whether colour and size are split into separate tracking codes. - Use code design: build the identifier from category, attributes, and a running sequence. - Use SKU analytics: analyse sales and trigger automatic replenishment at the SKU level.
Anchor fast decisions
Assigning a unique code to every separately countable and priced item lets purchasing, sales, inventory, and replenishment all track by the same key. That code becomes the base granularity of retail data, and the granularity chosen directly sets the trade-off between analytical precision and management cost.
