1. Macro – level product mix

Allocate store space to different categories depending on customer demand and size. Group stores to category specific clusters. Allocate appropriate space to each category in each cluster. 

Define each category cluster assortment structure at sub-category and product attribute (taste, price, size, etc.) levels ensuring that it meets customer needs, comply with store format, and maximize store financial KPIs.

2. Item – level product mix


Choose correct single SKUs to satisfy customer needs, maximize sales and profit, considering assortment structure and available space in category clusters, as well as commercial terms with suppliers. Take listing and de-listing decisions on single items, brands, suppliers. Optimize assortment fulfilling more costumer needs with the same number of SKUs and minimize sales cannibalization. Prepare merchandising requirements at SKU level with facings and shelf inventory.
