Marketing involves creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners and society. It is a societal process by which individuals and groups obtain what they need and want through creating, offering, and freely exchanging products and services. Marketing management is the art and science of choosing target markets and getting, keeping, and growing customers through creating, delivering and communicating superior customer value. Customer perceived value is determined by comparing the prospective customer's evaluation of the total benefits versus the total costs of an offering against alternative options.
