Successful businesses care for their customers at all times and keep it a top priority. In a successful business, everyone in the business thinks about creating, serving and satisfying customers throughout the entire day. Ten years after the book In Search Of Excellence, by Tom Peters and Robert Waterman, became a bestseller, a journalist asked Peters which of the seven principles in the book he felt were still the most important. Without hesitating he replied that it was "an obsession with customer service."
In the best businesses (large or small) the key people love their customers. They think about their customers day and night. They see themselves as personal representatives or agents of their customers, working on their customers' behalf. This attitude of devotion to customer wants and needs permeates the entire organization and causes people to want to do business with the company and continue doing business with it in the future.
You can always tell a good business by the way they treat their customers, how they answer the phone and deal with customer requests and inquiries, and how they deal with customer needs and complaints. Concern for the customer at all times is a top priority in all successful businesses.
