case STUDY: ASSORTMENT OPTIMIZATION

Determining the right shelf assortment is important to retail success.

Client

One of our leading European FMCG retail clients in its region, with a clientele of more than 1.2 million customers and more than 200 stores, was interested in improving their shelves assortment.

Within each store, they had multiple planograms and different strategies. Their business goal was to optimize their product categories, reduce the number of products on the shelves, reduce the number of planograms and identify the ideal and most profitable planogram.

Challenge

The current way of deciding which products will be on the shelves was based on shelves’ space and favorite products derived from customer surveys. Our Data Science team proposed an integrated method. To take into consideration the consumer behavior data for each store and incorporate product substitution probabilities.

We also had to ensure that the optimal planogram was placing the most productive SKUs in the right locations, in the most relevant stores to maximize profit. Our client also wanted to decrease the number of products at the chain level, decrease the number of planograms and also provide price variation on the shelves.

Solution

The algorithm was initially built to oversee local preferences and trends for each store and match each store’s customer preferences. You can learn many things about your customers from their purchase behaviours and product consumption. Especially if you focus on your top customers, based on highest Recency, Frequency, Monetary value (RFM). And this is what we did for our client. We tracked consumers behavior over a pre-defined period and identified all switching patterns.

Additionally, the algorithm selects products based on:

  • Estimated sales of a combination of products
  • Substitution probabilities (The proportion of the products’ sales, that can be allocated to all other products in the assortment, in case the former is delisted)
  • Share of each product sales
  • Ratio of each price category of each planogram
  • At least one product from each price category
