The NIST report entitled "Information Management Directions: The Integration Challenge" defines the Enterprise Architecture, levels within the Architecture, and the standards required to implement and enforce such an Architecture. The NIST Enterprise Architecture has provided a framework for service and agency architecture model definitions. It consists of a five-tiered framework to illustrate business, information, and technology interconnectivity. Although the tiers are separately identified, they are interrelated. An integrated set of information and information technology architectures can be derived from the Enterprise Architecture. In the 1990s the [[United States Department of Energy|Department of Energy]] (DOE) has adopted NIST’s Enterprise Architecture model to define its Information Architecture, see image.<ref name="FAA98"/>
