Know the competition. Find out who your competitors are, what they are offering and what their unique selling point (USP) is. This will identify the areas you need to compete in, as well as giving you a platform for differentiating yourself.
Know your customers. Customer expectations can change dramatically when economic conditions are unstable. Find out what matters to your customers now – is it lower price, more flexible service, the latest products? Revise your sales and marketing strategy accordingly.
