Enterprise Map setEnterprise maps are developed in a set of drawing based on the relevant space. It is possible to describe the enterprise in the same enterprise map specification based on the concept of Macrocosm and Microcosm. Macrocosm and microcosm is an ancient Greek Neo-Platonic schema of seeing the same patterns reproduced in all levels of the cosmos, from the largest scale (macrocosm or universe-level) all the way down to the smallest scale (microcosm or sub-sub-atomic or even metaphysical-level). In the system the mid-point is Man, who summarizes the cosmos.
Many ancient people other than the Greeks (Incas, Aborigines, Vikings and Celts, amongst others), observed the golden ratio in many parts of the ordered universe both large and small. The Greeks were philosophically concerned with a rational explanation of everything and saw the repetition of the golden mean throughout the world and all levels of reality as a step towards this unifying theory. In short, it is the recognition that the same traits appear in entities of many different sizes, from one man to the entire human population.
Today, the concept of microcosm has been dominated by sociology to mean a small group of individuals whose behavior is typical of a larger social body encompassing it. A microcosm can be seen as a special kind of epitome. Conversely, a macrocosm is a social body made of smaller compounds.

Enterprise Map drawing set
EA map is delivered in a set of architecture drawing to the stakeholders. Each business unit does not only have to comprehend their own big picture to know their own overall business and automation systems but also have to know the overall environment on the other business units. The drawing set is similar to the traditional architecture drawing set where the stakeholders can have tangible EA artifact where they can access in times of need.
The concept of one page is to render the holistic enterprise in one place to optimize the human comprehension. Each page can only encompass the bird view of enterprise at certain elevation. The drawing set enable a desending effort to drill down the EA map for more detail. However, a drawing set should not become overwhelming to contain tons of drawing as construction bluepirnt do.
From the EA topology drawing set , each business unit can learn, leverage and share the other business unit IT solutions from the similar lines of business.
This EA topology drawing set is composed individual page for each major business unit to illustrate the business unit from the aspect office type framework, business functions and high level processes, the associated automation systems to support the business functions , the data centers support the automation systems and the technology used in each automation system.
An over view topology to see the entire enterprise in one page is prepared in a bobble up process from each individual page of business unit. The overview page provide the overall big picture as the orientation for the stakeholder. It is at the level where the stakeholders can see the earth as a big blue marble.
It is suggested to start the EA topology drawing set with CIO topology because the Chief Information Office must know how to resolve their stove pipe systems to overcome the enterprise stove pipe systems. CIO integration is the locomotive to enable the enterprise wide automation integration.
EA topology drawings sets require dedicate resources to generate and update. It is suggest that business unit share the EA topology drawing sets. The EA topology drawing must be update periodically. The good news is that it does not requires real time update because it does reflect the on going detail.
How to drill down
EA map render enterprise information in a one comprehensible page from a high level. However, the one page big picture frequent induce the desire to drill down for more detail. As a result, EA map is frequently delivered in a set of drawings. The set of EA map drawings should not become overwhelming for human comprehension.
EA map dissemination
Business community like Hard copy works which requires significant effort to print and delivery.
Technical community like PDF version which is easy to produce and delivery but requires extra effort to comprehend.
The OCIO EA Map
