When building an assortment policy, it is important to understand which assortment types you will deal with. Classification is possible by such criteria as breadth, depth, saturation and specialization. Each item format has its own specifics, expressed in management methods, structuring principles and other nuances. Breadth This metric denotes the total number of product categories and subcategories. The larger it is, the greater the target-audience coverage and the stronger the company's competitive position.
For example, a supermarket's assortment is broader than a small grocery store's, so its footfall is usually higher. An online electronics store offers products for the widest possible segment of buyers, whereas a dealer of a specific smartphone brand has a target audience many times smaller. By breadth, an assortment can be simple or complex: the former includes a relatively small number of categories and items, the latter offers the customer a much wider choice. It can also be grouped or expanded.
In one case the item master consists of products similar in purpose and specifications; in the other it includes the widest possible range of diverse products. _Examples of assortment types by breadth_
| Simple | Complex | By group | Extended |
| Neighborhood household goods minimarket (average of 300-500 items) | Supermarket with many branches (10,000+ items) | A bakery store (products are similar in how they are made) | An audio equipment store (products differ by brand, purpose, design features, etc.) |
Depth This parameter denotes the number of items within a single product category. It affects target-audience coverage, customer satisfaction and sales growth. The greater the depth, the wider the segment of customers you can offer the product they need.
By this criterion the assortment is divided into two types: - type-based - the category consists of similar products with comparable characteristics; - brand-based - products of different types, but manufactured by the same company or belonging to the same line. _Examples of assortment types by depth_
| By species | By brand |
| A company producing all kinds of brick — wall brick, rough brick, decorative brick, ceramic brick with thermal insulation, etc. | A Samsung electronics store — the catalog features only this brand's products, but includes everything the company makes (phones, headphones, cameras, smartwatches, TVs and much more) |
Saturation This characteristic denotes the total number of all items in the assortment overall, taking into account breadth and depth. The more saturated the product range, the richer the choice offered to the customer, and therefore the higher the chance that a person will make a purchase in this particular store. It is important to remember that as saturation grows, so do the store's costs for purchasing, storage and logistics.
