The satisfaction of a consumer can be best explained by the marketing concept.
The marketing concept is a business philosophy that focuses on identifying and meeting the needs and wants of consumers. It involves understanding the target market and delivering superior value to them by providing high-quality products or services that meet their needs and wants.
By adopting the marketing concept, a business can tailor its products or services to the specific needs of its customers, and this can lead to higher levels of customer satisfaction. In turn, satisfied customers are more likely to become loyal customers and spread positive word-of-mouth about the business, which can ultimately lead to increased sales and profits.
While product mix, marketing mix, and market segmentation are all important components of a business's overall marketing strategy, they are all ultimately aimed at achieving the marketing concept - delivering value to customers.
