Diagrams I built from 1982 that illustrate the concept I was applying for enterprise management. They now correspond to both a methodology and ontology for implementing an enterprise management system, consisting of an operations lifecycle integrated with an enterprise architecture as a knowledge-base or knowledge-organization system. Predecessor to Zachman Architecture Framework of 1984 and 1987.
