the strategic (row one) level, this is a description of the business cycle and overall business events. The Zachman Framework of enterprise architecture. Dave’s recently-published book, “Enterprise Model Patterns: Describing the World”, is an “upper ontology” consisting of a comprehensive model of any enterprise—from several levels of abstraction. Each new approach, while it doesn’t represent the millenium (or a way of dealing with it), does contribute to the body of knowledge. The rows represent the points of view of different players in the systems development process, while columns represent different aspects of Production – The ongoing monitoring of the system to ensure that it continues to meet the needs of the organization. Still more detailed views were created for the people who would actually build the infrastructure, while others were created for electricians, plumbers, and those who would finish the interior. John A. Zachman Chief Executive Officer, Zachman International . He has added three columns, People, Time, and Motivation, and has started calling it an Enterprise Architecture. any company in this industry, affecting its direction and purpose. Based on the Zachman EA framework, strategic alignment and governance is an integral part of security in developing an enterprise security framework, and all security needs for data, application, and technology dimensions need to derive from business (Fumy & Sauerbrey, 2006; Sherwood, 2005; Zachman, 1987). The Zachman framework should be comprised of architectural primitives from whom the application development work products can be derived. It was the brainchild of John Zachman during the year 1987. Schedule Strategy Scope Contextual Planner In the detailed model of the business (row two), the time column place. … We'll start with row one, column one, Executive What?

Function: The rows in the function column describe the process of translating the mission of the enterprise into successively more detailed definitions of its operations. This is an industry view, concerned with the things that define the nature and purpose of the At row two, this becomes a more detailed communications chart, describing how the various locations interact with each other. In row two, this list is fleshed out into a full organization chart, linked to the function column. John Zachman’s “Framework” is diagrammed in Figure 1. This holistic schema, which addresses multiple perspectives and multiple abstractions, is a very powerful concept that can be applied to managing enterprise architecture (EA) documentation. recognize that systems are developed by distinct groups with different points of view, than that it is to see the movement of systems from one step to another. At the strategic level (row one), this is simply a listing ofthe places where the enterprise does business. Mr. Zachman does not advocate the use of any particular modeling style for those cells where multiple It is a proactive business tool, which can be used to model an organisation’s existing functions, elements and processes - and help manage business change. Analysis – The detailed definition of requirements for a particular area of the business. The columns describe the dimensions of the systems development effort. been some significant gains. The technology model in row four then converts these data Cookie information is stored in your browser and performs functions such as recognising you when you return to our website and helping our team to understand which sections of the website you find most interesting and useful. This is expressed as consisting of: Strategy – The planning of an organization’s overall systems development effort. Row six describes the implemented communications facilities. This represents an assignment for us all. In row three, the potential interaction between people and technology begins to be specified, specifically in terms of who needs what information to do We are using cookies to give you the best experience on our website. It is difficult, for example, to model the logic (row three) of a distributed information Technology model (Designer’s view): This describes how technology may be used to address the information processing needs identified in the previous rows. In row four, this distribution is translated terms of data transforming processes, described exclusively in terms of the conversion of input data into output data. The scope of the four architecture domains of TOGAF aligns very well with the first four rows of the Zachman Framework, as shown in the following mapping of these domains: Several domains overlap in the above diagram: the earliest domain to address a cell has precedence in the coloring scheme. Thus, Enterprise Applications originally referred to systems like accounting, payroll, and bookkeeping that were run on mainframes, maintained in central locations, and used to maintain a companyâs accounts and generate all the paychecks. The second is derived from reification, the transformation of an abstract idea into an instantiation that was initially post… Row three defines the business events which cause specific data transformations and entity state changes to take Zachman Framework v1 What How Where Who When Why Viewpoint Idealisation Stakeholder Data Function Network Org. In the technology model (row four), the events become program triggers and messages, and the information processing responses are designed in detail. There are two extreme approaches for creating an Enterprise Architecture using the Zachman Framework; Top Down and Bottom Up. In the Information Industry since it was called “data processing”, Dave Hay has been producing data models to support strategic and requirements planning for thirty years. Zachman Framework provides structured and disciplined way of defining an enterprise. Where row two described business People: The fourth column describes who is involved in the business and in the introduction of new technology. conversion processes into the definition of program modules and how they interact with each other. You can find out more about which cookies we are using or switch them off in settings. In row six business events are correctly responded to by the system. There is a lot of interest currently in the Zachman Framework. The Zachman Framework is a schema - the intersection between two historical classifications that have been in use for literally thousands of years. 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 The second is derived from the philosophical concept of reification, the transformation of an abstract ide 3. Each row of the Zachman Framework will be examined to determine if the documentation would be needed. Projects entailed defining corporate information architecture, identifing requirements, and planning strategies for the implementation of new systems. 1.
