In 1987, John Zachman, wrote: “To keep the business from disintegrating, the concept of information systems architecture is becoming less of an option and more of a necessity.” From then on, the Enterprise Architecture Framework of Zachman has evolved and became the model around which many major organizations view and communicate their enterprise information infrastructure. It provides a blueprint, or architecture, for the organization’s current and future information infrastructure.

The Zachman Enterprise Architecture at the time presented a new model for viewing and communicating information infrastructures. Instead of representing the process as a series of steps, he organized it around the points of view (perspectives) taken by the various players. These players included: 1. someone who has undertaken to do business in a particular industry, 2. the business people who run the organization, 3. the systems analyst who wants to represent the business in a disciplined form, 4. the designer, who applies specific technologies to solve the problems of the business, 5. the builder of the system, and finally 6. the system itself. These perspectives are represented as rows in the matrix.

Zachman also acknowledged that each of the participants was looking at the same categories of information. The columns in the framework represent the data manipulated by an organization (what), its functions and processes (how), locations where business is conducted (where), events that trigger business activities (when), the people and organizations involved (who), and the motivations and constraints which determine how the business behaves (why).
