Answer:
the assortment of each item carried by a store.
Explanation:
Product depth can refer to both a retailer or a manufacturing company.
Regarding a retailer, product depth refers to the assortment within each product line that the retailer has available for sale. If a store increase its product depth of a certain particular product line, it means it will offer more products of the same product line, e.g. Coke, Coke Zero, Diet Coke sold in cans or bottles, individually or in packs. Stores that want to keep low inventories will have a shallow product depth, meaning that they will only offer few units of every product line that they sell.
A manufacturer's product depth refers to the amount of products that are included under a single product line. A product line is made up of the products that a company sells under one brand. If a company increases its product depth it means that it will offer more products under the same brand, either by introducing completely new related products or variations of existing products.
