Marketing is defined by the American Marketing Association as “the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large”. The term developed from the original meaning which referred literally to going to market with goods for sale. From a sales process engineering perspective, marketing is “a set of processes that are interconnected and interdependent with other functions” of a business aimed at achieving customer interest and satisfaction”.
Philip Kotler defines marketing as “Satisfying needs and wants through an exchange process”.
The Chartered Institute of Marketing defines marketing as “the management process responsible for identifying, anticipating and satisfying customer requirements profitably”. A similar concept is the value-based marketing which states the role of marketing to contribute to increasing shareholder value.[8] In this context, marketing can be defined as “the management process that seeks to maximise returns to shareholders by developing relationships with valued customers and creating a competitive advantage”.
