Lastly, before finalizing it is vital to advertise the product to the consumers to create awareness. The promotion of the product must include the benefits and values that the product contains in order to inspire and interest the targeted consumers into investing in the product or service offered by the firm. If businesses sell their product cost efficiently to their customers and provide the best experience through the use of their products, then it is expected that existing customers will "spread the word" increasing sales and profit for the business. However, it is important that the business ensures at all times that they are satisfying the needs of their consumers according to the customer value proposition as firms can face lack of profit and sales if the consumers are not satisfied with the brand of product at any point of time.
