Products are classified based on durability, tangibility and use. Consumer goods are classified as convenience, shopping, specialty or unsought. Industrial goods are materials/parts, capital items or supplies. Companies can differentiate products through various attributes. A product hierarchy consists of need families, product families, product classes, product lines and items. Companies manage product mixes through lines, assortments, depth, length and width.
