Assortment Potential Analysis

An assortment that is not managed on a data basis does not fully realise its margin and growth potential. Many manufacturers and brands list products on marketplaces and with online retailers without systematically understanding which categories are actually growing profitably and where they are losing visibility relative to the competition. FOSTEC & Company’s assortment-potential analysis creates this transparency and translates it into concrete, prioritised recommendations for action.

Context and relevance

In online retail, it is no longer the product alone that determines success, but its visibility on the digital shelf. Algorithms, search logic and platform mechanics determine which products are seen, bought and scaled. At the same time, complexity is increasing through fragmented sales channels, dynamic pricing logic and data-driven competitive strategies. Many companies, however, continue to manage their assortment on the basis of historical sales data or isolated channel perspectives. This leads to misallocations: products are expanded even though they achieve no sustainable visibility or profitability, while structurally attractive growth fields remain untapped. Well-founded assortment management requires an integrated understanding of demand, competition and profitability – across the entire digital ecosystem.

Our approach

FOSTEC & Company places assortment decisions on a robust, quantitative foundation. The approach follows a three-stage filtering process that derives a clearly prioritised focus assortment from the breadth of available market data (Figure 1: Three-stage filtering process for assortment optimisation – from the digital shelf to the focus assortment):

1. Category revenue potential: Using AI-supported market sizing and search-volume analyses, it is quantified in which categories relevant demand exists and where structural growth opportunities lie.
2. Competitive position at SKU level: Using a digital shelf score, metrics such as share of search, content quality, buy-box rate and visibility are analysed – with a precise assessment of where the assortment lags behind the competition or performs above average.
3. Profitability: Contribution margins are analysed taking account of platform fees, advertising costs and return rates, in order to ensure that growth is economically viable.

In addition, each product category is positioned in a category attractiveness matrix that links external market attractiveness with internal delivery capability (Figure 2: Category attractiveness matrix – prioritisation by external market attractiveness and internal delivery capability). This framework makes visible which categories should be scaled, which developed and which critically reviewed. The bubble size represents the respective revenue or EBIT potential – thereby creating a clear prioritisation map for the entire portfolio.
