Soon, the enterprise of the information age will find itself immobilized if it does not have the ability to tap the information resources within and without its boundaries.
Decentralization without structure is chaos.
p. 276 cited in: Robert Mylls (1994)
When the rate of change increases to the point that real time required to assimilate change exceeds the time in with change must be manifest, the enterprise is going to find itself in deep yogurt.
Zachman (1994)
There is a set of architectural representations produced over the process of building a complex engineering product representing the different perspectives of the different participants.
p. 283. cited in: Stephen L. Montgomery (1994)
To keep the business from disintegrating, the concept of information systems architecture is becoming less of an option and more of a necessity
With increasing size and complexity of the implementations of information systems, it is necessary to use some logical construct (or architecture) for defining and controlling the interfaces and the integration of all of the components of the system.
[Zachman reasons that] an analogous set of architectural representations is likely to be produced in building any complex product.
Architecture is that set of design artifacts, or descriptive representations, that are relevant for describing an object, such that it can be produced to requirements (quality) as well as maintained over the period of its useful life (change).
The analytical approach employed by both BSP and BISC is "top down". The implications of the words "top down" are multiple and varied, and all apply to these analysis. For instance
Business System Planning (BSP) and Business Information Control Study (BICS) are representative of enterprise analysis tools that are growing in importance and are likely to become mandatory for ant business that continues to grow and evolve.
[In Mr. Zachman's view] the architect's drawings [represent] a transcription of the owner's perceptual requirements.
p. 278 cited in: David C. Hay (2003)
(Enterprise Architecture is) the set of descriptive representations (i.e., models) that are relevant for describing an Enterprise such that it can be produced to management's requirements (quality) and maintained over the period of its useful life.
Zachman (1987)
It is not adequate merely to produce running code. In the long term, enterprise value lies in the models themselves. They have intrinsic value in their own right, as they constitute the baseline for managing change
It is only the advent of an automated model storage facility or repository that brings any of this into the realm of feasibility and makes architecture a reality. It does not mean to suggest that all of these ideas will be immediately available in any particular repository product. It only means that they come into the realm of feasibility as repository technology becomes a reality.
The Information Age is unfolding just as predicted by many of the sociological prognosticators of this century. Information issues are on everyone’s mind and on multitudes of lips. It is hard to pick up a newspaper or current affairs magazine without seeing a feature on the internet, web pages, e-mail, television terminals or some other new technology. In fact, technology innovation is relentless and escalating and technology stocks continually drive the stock market to high after high. There is no field of human endeavor that is exempt from the onslaught of information technology.
