( Log Out / The Zachman Framework™ IS NOT a methodology for creating the implementation (an instantiation) of the object. The Framework for Enterprise Architecture: Background Description and Utility. The ontology is a two dimensional classification schema that … Let us have a look at these levels in some more details. Zachman framework for architecture is the next step: less primitive, more sophisticated. Since the Zachman Framework™ classification was observed empirically in the structure of the descriptive representations (the architecture) of buildings, airplanes and other complex industrial products, there is substantial evidence to establish that the Zachman Framework™ is the fundamental structure for Enterprise Architecture and thereby yields the total set of descriptive representations relevant for describing an Enterprise. . Zachman® and Zachman International® are registered trademarks of Zachman International, Inc. The Zachman Frame work defines thirty six different perspectives. ( Log Out / ZF provides an effective meta-model for large scale information systems by means of a set of architectures. It includes technical viewpoint about the architecture as well as logistic details about how and where it will be implemented and by whom. Video: Zachman Framework example. It is helpful to think of the levels in terms of the intended audience: I also find the Why, How, What ... thing to be less than clear. Because architecture is important. At this level just the identification of the processes is needed. The Differences between Zachman Framework and TOGAF Framework Rule 1: Do not add rows or columns to the framework. The Zachman Framework is a schema - the intersection between two historical classifications that have been in use for literally thousands of years. Zachman Framework is a two-dimensional classification scheme for descriptive representations of an Enterprise that is structured as a matrix containing 36 cells, each of them focusing on one dimension or perspective of the enterprise. The true measure of an idea’s elegance lies in its simplicity. Whether you do Architecture or whether you simply build implementations that is, whether you build Primitive Models, the ontological, single-variable intersections between the Interrogatives and the Transformations or whether you simply build ad hoc, multi-variable, composite models made up of components of several Primitive Models. The Zachman Framework, developed by John Zachman, is an enterprise ontology and is a fundamental structure for Enterprise Architecture which provides a formal and structured way of viewing and defining an enterprise. The Framework classifications are represented by the Cells, that is, the intersection between the Interrogatives and the Transformations. In this, the first of a two-part series, John P. Zachman covers the early years of The Framework, beginning in 1984. 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. The long-term/short-term trade-off relative to instantiating the expression of the components of the object that is, what is formalized in the short-term for implementation purposes versus what is engineered for long-term reuse. How you do Architecture: top-down, bottom-up, left to right, right to left, where to start, etc., etc. Though he might know about the scope of the system, knowing the java class will be more important for him. TrackBack URI, Pingback by Enterprise Architecture Tutorial « Enterprise Architecture Beginner Guide— November 14, 2011 #. At row two, this becomes a more detailed communications chart, describing how the various locations interact with each other. The Zachman Framework, the Owner’s Perspective & Security L. Ertaul1, V. Rathod1 1Mathematics and Computer Science, CSU East Bay, Hayward, CA, USA Abstract – The Zachman Framework is one of the oldest Enterprise Architecture Frameworks. Copy. A complete system can be modeled by depicting answers to the questions why, who, what, how, where and when. 1. Its goal (Why), its process (How), modelling (What), organisational structure (who), Implementation location (where) and timelines (when). This matrix would necessarily constitute the total set of descriptive representations that are relevant for describing something... anything: in particular an enterprise. They read like a litany for IRM. Change ). A Tutorial on the Zachman Framework for Enterprise Architecture 2. The Zachman framework is a great way to think about the relationships between systems, data, processes and business. At the strategic level (row one), this is simply a listing ofthe places where the enterprise does business. The first is the fundamentals of communication found in the primitive interrogatives: What, How, When, Who, Where, and Why. The FEAC Institute offers access to training and certification in the Zachman Framework™ offered by Zachman International®, who's home is at www.Zachman.com. Network: This column is concerned with the geographical distribution of the enterprise’s activities. O Zachman Framework é um framework para arquitetura corporativa que provê um meio formal e altamente estruturado de definir uma corporação. (Where) Geographical Locations List – locations important to organization; can be large and small, (When) Event List – list of triggers and cycles important to organization, (Why) Goal Relationship Model – identifies hierarchy of goals that support primary goals, – provides process descriptions, input processes, output processes, – identifies and describes the organizational materials and their relationships, (Who) Organizational Unit & Role Relationship Model – identifies enterprise roles and units and the relationships between them, (Where) Locations Model – identifies enterprise locations and the relationships between them, (When) Event Model – identifies and describes events and cycles related by time, (Why) Rules Diagram – identifies and describes rules that apply constraints to processes and entities without regard to physical or technical implementation, – identifies and describes process transitions expressed as verb-noun phrases without regard to physical or technical implementation, – identifies and describes entities and their relationships without regard to physical or technical implementation, (Who) Role Relationship Diagram – identifies and describes roles and their relations to other roles by types of deliverables without regard to physical or technical implementation, (Where) Locations Diagram – identifies and describes locations used to access, manipulate, and transfer entities and processes without regard to physical or technical implementation, – identifies and describes events related to each other in sequence, cycles occur within and between events, without regard to physical or technical implementation, (Why) Rules Specification – expressed in a formal language; consists of rule name and structured logic to specify and test rule state, (How) Process Function Specification – expressed in a technology specific language, hierarchical process elements are related by process calls, (What) Data Entity Specification – expressed in a technology specific format; each entity is defined by name, description, and attributes; shows relationships, (Who) Role Specification – expresses roles performing work and workflow components at the work product detailed specification level, (Where) Location Specification – expresses the physical infrastructure components and their connections, (When) Event Specification – expresses transformations of event states of interest to the enterprise, Enterprise Architecture Tutorial « Enterprise Architecture Beginner Guide.
