A product is anything offered for sale to satisfy customer needs and can be tangible or intangible. A company's product mix includes all of its product lines, which are groups of related products. PepsiCo for example has product lines for beverages, food, and nutrition. The depth, width, and length refer respectively to the variations within lines, total number of lines, and total number of products. Nike's example product mix shows lines for footwear, apparel, and equipment with depth, width, and consistency characteristics.
