Here we discuss the interfaces and relationships between operations and marketing. Let's define the marketing - operations relationship. Marketing is the management of exchange processes to satisfy wants and needs and relationships.
Operations is the management of the production of goods and services to be exchanged.
The two are tightly connected. You cannot have one without the other. The separate functions of marketing - selling, advertising, marketing research, new product development, customer service, and physical distribution, depend on operations to control cost, quality, delivery, and flexibility of product or service offerings. Therefore both operations and marketing stress cost and delivery management. Most products, as they enter the mature stages of their product life cycle, fall into this category.
