Another application of the Zachman Framework is as reference model for other enterprise architectures, see for example these four:. In the s John Zachman had been involved at IBM in the development of business system planning BSP , a method for analyzing, defining and designing an information architecture of organizations. It is a set of things, in fact, a set of 30 descriptive representations relevant for describing a complex object such that it can be created that is, engineered, optimized so it meets its design objectives and relevant for changing that is, improving the object over time.
The Framework as a classification structure, in its most generic form appears below:. This has enabled enormous increases in product sophistication and the ability to manage high rates of product change over time. The Framework is a generic classification scheme for design artifacts, that is, descriptive representations of any complex object. The utility of such a classification scheme is to enable focused concentration on selected aspects of an object without losing a sense of the contextual, or holistic, perspective.
In designing and building complex objects, there are simply too many details and relationships to consider simultaneously. However, at the same time, isolating sub-sets or components and making design decisions out of context results in sub-optimization with all its attendant costs and dissipation of energy entropy. Restoration of integrity or retrofitting the sub-optimized components of the resultant object, such that they might approximate the purpose for which the object was originally intended, may well be financially prohibitive if not logically impossible.
This is the condition in which many Enterprises find themselves today after about fifty years of building automated systems, out-of-context. They have a large inventory of current systems, built out-of-context, not integrated, not supporting the Enterprise, that are consuming enormous amounts of resource for maintenance and are far and away too costly to replace.
A balance between the holistic, contextual view and the pragmatic, implementation view can be facilitated by a Framework that has the characteristics of any good classification scheme, that is, it allows for abstractions intended to:. It makes little difference whether the object is physical, like an airplane or a building or a computer, or conceptual, like an Enterprise.
The challenges are the same. How do you design and build it piece-by-piece such that it achieves its purpose without dissipating its value, raising its operating costs and inhibiting or prohibiting change by optimizing the pieces and sub -optimizing the object.
It is a comprehensive, logical structure for descriptive representations i. The classification is holistic, complete and it is stable. The same classification on both axes has been employed by humanity for thousands of years. It is not going to change. If it is employed with understanding, it should be of great benefit to technical and non-technical management alike in dealing with the complexities and dynamics of the Information Age Enterprise.
If the models as specified by the Framework were operationalized for a given Enterprise, engineering design objectives like alignment quality , integration, flexibility, interoperability, reusability, etc.
The models, if retained and maintained, would serve as a baseline for managing change. These are the characteristics of architecture for anything. Architecture is not one thing. It is a set of things, in fact, a set of 30 descriptive representations relevant for describing a complex object such that it can be created that is, engineered, optimized so it meets its design objectives and relevant for changing that is, improving the object over time.
This is true for Enterprises just as it is true for buildings, airplanes, automobiles, bridges, super computers, battleships, semi-conductor chips or any other complex object. The framework is generic in that it can be used to classify the descriptive representations of any physical object as well as conceptual objects such as enterprises. It is also recursive in that it can be used to analyze the architectural composition of itself.
Although the framework will carry the relation from one column to the other, it is still a fundamentally structural representation of the enterprise and not a flow representation.
One of the strengths of the Zachman Framework is that it explicitly shows a comprehensive set of views that can be addressed by enterprise architecture. Zachman, however, indicates that only the facts needed to solve the problem under analysis need be populated.
John Zachman clearly states in his documentation, presentations, and seminars that, as framework, there is flexibility in what depth and breadth of detail is required for each cell of the matrix based upon the importance to a given organization.
An automaker whose business goals may necessitate an inventory and process-driven focus, could find it beneficial to focus their documentation efforts on What and How columns. By contrast, a travel agent company, whose business is more concerned with people and event-timing, could find it beneficial to focus their documentation efforts on Who , When , and Where columns. However, there is no escaping the Why column's importance as it provides the business drivers for all the other columns.
Since the s the Zachman Framework has been widely used as a means of providing structure for information technology engineering -style enterprise modeling. Within a government organization the framework can be applied to an entire agency at an abstract level, or it can be applied to various departments, offices, programs, subunits and even to basic operational entities. Zachman Framework is also used as a framework to describe standards, for example standards for healthcare and healthcare information system.
Each cell of the framework contains such a series of standards for healthcare and healthcare information system. Another application of the Zachman Framework is as reference model for other enterprise architectures, see for example these four:. This methodology required defining all aspects of the VA enterprise from a business process, data, technical, location, personnel, and requirements perspective.
The next step in implementing the methodology has been to define all functions related to each business process and identify associated data elements. Once identified, duplication of function and inconsistency in data definition can be identified and resolved,.
The Department of Veterans Affairs at the beginning of the 21st century [ when? Eventually an enterprise architecture repository was created at the macro level by the Zachman framework and at a cell level by the meta-model outlined below.
Caliber-RM is intended to be used as a software configuration management tool; not as an EA repository.
However, this tool permitted defining entities and relationships and for defining properties upon both entities and relationships, which made it sufficient for building an EA repository, considering the technology available in early The personal motivation in selecting this tool was that none of the commercial repository tools then available provided a true Zachman Framework representation, and were highly proprietary, making it difficult to incorporate components from other vendors or from open source.
This diagram emphasizes several important interpretations of the Zachman Framework and its adaptation to information technology investment management. Row-six provides measured return on investment for Individual Projects and, potentially, for the entire investment portfolio. Without row-six the Framework only identifies sunk-cost, but the row-six ROI permits it to measure benefits and to be used in a continuous improvement process, capturing best practices and applying them back through row-two.
This criticism suggests that the Zachman Framework can hardly reflect actual best practice in EA.
