A group of individuals, functions, and sometimes legally separate but operationally synchronized organizations. The value stream defines the lean enterprise. The objectives of the lean enterprise are to correctly specify value to the ultimate customer, and to analyze and focus the value stream so that it does everything from product development and production to sales and service in a way that actions that do not create value are removed and actions that do create value proceed in a continuous flow as pulled by the customer. Lean enterprise differs from a “virtual corporation” in which the organizational membership and structure keeps changing.
