From a societal point of view, marketing is the link between a society’s material requirements and its economic patterns of response. Marketing satisfies these needs and wants through exchange processes and building long term relationships. Marketing can be looked at as an organizational function and a set of processes for creating, delivering and communicating value to customers, and managing customer relationships in ways that also benefit the organization. In the consumer-driven approach, consumer wants are the drivers of all strategic marketing decisions. No strategy is pursued until it passes the test of consumer research. Every aspect of a market offering, including the nature of the product itself, is driven by the needs of potential consumers. A marketing strategy differs from a marketing tactic in that a strategy looks at the longer term view of the products, goods, or services being marketed. A tactic refers to a shorter term view. Therefore, the mailing of a postcard or sales letter would be a tactic, but changing marketing channels of distribution, changing the pricing, or promotional elements used would be considered a strategic change.
