"The history of enterprise architecture as a management discipline has been marked by failure to live up to the promise it showed as a concept. The idea of an enterprise architecture and the explicit understanding of the relationships between the most critical forces, resources, and processes involved in the execution of an organization’s business is powerful. People can grasp on an intuitive level how powerful the reality of that concept would be if it could be put into practice and harnessed on behalf of the enterprise. Unfortunately, the conceptual enterprise architecture that enables the agile enterprise and informs executives in the midst of critical portfolio and execution decisions has given way to a morass of additional bureaucracy and expensive efforts to create enterprise models that are more often significant as records of organizational history than as blueprints for the future. The problems lie in three areas. The first of which is a lack of clear performance objectives for the EA effort... The second major failure stems from the belief that EA is somehow all about the process for developing content... Finally, there is far too little attention paid to helping the consumers of EA information..."
