It includes all the different product lines and individual products that a company sells, as well as any variations in size, color, flavor, or other attributes. A company's product mix is an important aspect of its overall marketing strategy, as it helps to define the company's brand and target market. By carefully managing their product mix, companies can appeal to a wider range of customers and increase their overall sales and profitability.
