With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase.

The approach became known as the positioning school because of its emphasis on locating a defensible competitive position within an industry or sector. In this approach, strategy formulation consists of three key strands of thinking: analysis of the five forces to determine the sources of competitive advantage; the selection of one of three possible positions which leverage the advantage and the value chain to implement the strategy.
