Русско-англо-русский юридический словарь

the variety of product lines that a company produces, or that a retailer stocks. Product assortment usually refers to the length (the number of products in the product line), breadth (the number of product lines that a company offers), depth (the different varieties of product in the product line), and consistency (the relationship between products in their final destination) of product lines." (QFINANCE Dictionary)

And because a diverse product assortment often lacks a clear value proposition, the marketing and promotion budget is not spent effectively. (BCG Perspectives)
