The single most important thing to remember about any enterprise is that results exist only on the outside.The result of a business is a satisfied customer. The result of a hospital is a satisfied patient. The result of a school is a student who has learned something and puts it to work ten years later. Inside an enterprise there are only costs.
Peter DruckerInformation is the manager's main tool, indeed the manager's capital, and it is he who must decide what information he needs and how to use it.
