Marketing is defined as creating value for customers through an organization's products and services. It involves identifying customer needs, delivering products and services to meet those needs, and developing relationships to benefit both the customer and organization. Marketing management is the process of choosing target markets and attracting, retaining and growing customers through superior value. The goal of marketing is to understand customers so well that the product sells itself without needing sales. Marketing can promote a wide range of goods, services, ideas and organizations through communication channels and supply chains while addressing customer needs, wants and demands.
