Product variation refers to an activity undertaken by a firm to increase demand.
Product variation refers to the number of variants in which a product is available. The product from which the variations are created, is called the main product.
Product variation refers to the attribute based on which a product varies. For example: A company offers 4 different color T- shirts in 4 different sizes, then the product variation will be 16.
Product variation offers the customer more choice and hence increases the customer satisfaction. It therefore increases demand of the company product.
