'[[File:Zachman Framework Model.svg|thumb|360px|Current view of the Zachman Framework.]] The '''Zachman Framework''' is an [[Enterprise Architecture framework]] for [[enterprise architecture]], which provides a formal and highly structured way of [[view model|viewing]] and defining an enterprise. It consists of a two dimensional classification matrix based on the intersection of six communication questions (What, Where, When, Why, Who and How) with six rows according to [[Reification (computer science)|reification]] transformations.<ref>{{cite web|url=http://www.zachmaninternational.com/concise%20definition.pdf|title=John Zachman’s Concise Definition of the{{sic|hide=yes}} The Zachman Framework | publisher=Zachman International|year=2008}}</ref> The Zachman Framework is not a [[methodology]] in that it lacks specific methods and processes for collecting, managing, or using the information that it describes.<ref>{{cite web|url=http://www.zachmaninternational.com/index.php/home-article/13#maincol|title=The Zachman Framework: The Official Concise Definition | publisher=Zachman International|year=2008}}</ref> The Framework is named after its creator [[John Zachman]], who first developed the concept in the 1980s at [[IBM]]. It has been updated several times since.<ref>John Baschab, Jon Piot, Nicholas G. Carr (2007).

[[File:Zachman Frameworks Collage.jpg|thumb|320px|Collage of Zachman Frameworks as presented in several books on Enterprise Architecture from 1997 to 2005.]] In other sources the Zachman Framework is introduced as a framework, originated by and named after John Zachman, represented in numerous ways, see image. This framework is explained as, for example: * a [[Software framework|framework]] to organize and analyze [[data]]<ref>[[William H. Inmon]], [[John A. Zachman]], Jonathan G. Geiger (1997). ''Data Stores, Data Warehousing, and the Zachman Framework: Managing Enterprise Knowledge''. McGraw-Hill, 1997. ISBN 0070314292.</ref>, * a framework for enterprise architecture.<ref>Pete Sawyer, Barbara Paech, Patrick Heymans (2007). ''Requirements Engineering: Foundation for Software Quality''. page 191.</ref> * a [[Classification (machine learning)|classification]] system, or classification scheme<ref>Kathleen B. Hass (2007).

''Enterprise Architecture Using the Zachman Framework‎''. page 9.</ref> Beside the frameworks developed by John Zachman numerous extensions and or applications have been developed, which are also sometimes called Zachman Frameworks. The Zachman Framework summarizes a collection of [[Perspective (cognitive)|perspective]]s involved in enterprise architecture. These perspectives are represented in a two-dimensional matrix that defines along the rows the type of [[stakeholder (corporate)|stakeholder]]s and with the columns the aspects of the architecture. The framework does not define a methodology for an architecture. Rather, the matrix is a template that must be filled in by the goals/rules, processes, material, roles, locations, and events specifically required by the organization. Further modeling by mapping between columns in the framework identifies gaps in the documented state of the organization.<ref name="GASLSJ03">James McGovern et al. (2003). ''A Practical Guide to Enterprise Architecture''. p. 127-129.</ref> The framework is a simple and logical structure for classifying and organizing the descriptive [[representations]] of an enterprise. It is significant to both the [[management]] of the enterprise, and the actors involved in the development of enterprise systems.<ref name="Lank05">Marc Lankhorst (2005). ''Enterprise Architecture at Work''. p. 24.</ref> While there is not order of priority for the columns of the Framework, the top-down order of the rows is significant to the alignment of business concepts and the actual physical enterprise. The level of detail in the Framework is a function of each cell (and not the rows). When done by IT the lower level of focus is on [[information technology]], however it can apply equally to physical material (ball valves, piping, transformers, fuse boxes for example) and the associated physical processes, roles, locations etc. related to those items. == History == In the 1980s [[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. In 1982 Zachman<ref name="Zach82">[http://www.research.ibm.com/journal/sj/211/ibmsj2101D.pdf "Business Systems Planning and Business Information Control Study: A comparisment]. In: ''IBM Systems Journal'', vol 21, no 3, 1982. p. 31-53.</ref> had already concluded that these analyses could reach far beyond automating [[systems design]] and managing data into the realms of strategic business planning and management science in general. It may be employed in the (in that time considered more esoteric) areas of enterprise architecture, data-driven systems design, data classification criteria, and more.<ref name="Zach82"/> === Information Systems Architecture Framework === [[File:ZFArticlePages.jpg|thumb|210px|The original 1987 "Information Systems Architecture Framework".]] [[File:Zachman Framework Detailed.jpg|thumb|320px|Simple example of the 1992 Framework.]] In the 1987 article "A Framework for Information Systems Architecture"<ref name="Zach87">John A.

IBM Publication G321-5298.</ref> Zachman noted that the term "architecture" was used loosely by information systems professionals, and meant different things to planners, designers, programmers, communication specialists, and others.<ref name="Jac92">Durward P.

Proceedings of 1992 Information Resources Management Association International Conference''. Mehdi Khosrowpour (ed). ISBN 1878289179.</ref> In searching for an objective, independent basis upon which to develop a framework for information systems architecture, Zachman looked at the field of classical [[architecture]], and a variety of complex engineering projects in industry. He saw a similar approach and concluded that architectures exist on many levels and involves at least three perspectives: raw material or [[data]], function of processes, and location or networks.<ref name="Jac92"/> The Information Systems Architecture is designed to be a [[classification schema]] for organizing architecture models. It provides a synoptic view of the models needed for enterprise architecture. Information Systems Architecture does not define in detail what the models should contain, it does not enforce the modeling language used for each model, and it does not propose a method for creating these models.<ref>[[Alain Wegmann]] et al.

Keri Anderson Healey assisted by creating a model of the models (the framework metamodel) which was also included in the article.|Stan Locke|''Enterprise Convergence in Our Lifetime, from THE ENTERPRISE NEWSLETTER''<ref name="Locke08">Stan Locke (2008).

In the early 1980s however, according to Zachman, there was "little interest in the idea of Enterprise Reengineering or [[Enterprise Modeling]] and the use of formalisms and models was generally limited to some aspects of application development within the Information Systems community".<ref name="Zach97">John A.

Vol VII, No. 2, 2006 p. 257-262.</ref> == Zachman Framework topics == === Concept === The basic idea behind the Zachman Framework is that the same complex thing or item can be described for different purposes in different ways using different types of descriptions (e.g., textual, graphical). The Zachman Framework provides the thirty-six necessary categories for completely describing anything; especially complex things like manufactured goods (e.g., appliances), constructed structures (e.g., buildings), and enterprises (e.g., the organization and all of its goals, people, and technologies). The framework provides six increasingly detailed views or levels of abstraction from six different perspectives.<ref name="VA01">VA Enterprise Architecture Innovation Team (2001). [http://www.va.gov/oirm/architecture/ea/2002/VAEAVersion-10-01.pdf ''Enterprise Architecture: Strategy, Governance, & Implementation''] report Department of Veterans Affairs, August, 2001.</ref> It allows different people to look at the same thing from different perspectives. This creates a holistic view of the environment, an important capability illustrated in the figure.<ref>[http://www.inmongif.com/_fileCabinet/gifzach.pdf The government information factory and the Zachman Framework] by W. H. Inmon, 2003. p. 4. Accessed July 14, 2009.</ref> === Views or Rows === Each row represents a total view of the solution from a particular perspective. An upper row or perspective does not necessarily have a more comprehensive understanding of the whole than a lower perspective. Each row represents a distinct, unique perspective; however, the deliverables from each perspective must provide sufficient detail to define the solution at the level of perspective and must translate to the next lower row explicitly.<ref name="CIOC99">The Chief Information Officers Council (1999). [http://www.cio.gov/documents/fedarch1.pdf Federal Enterprise Architecture Framework Version 1.1]. September 1999</ref> Each perspective must take into account the requirements of the other perspectives and the restraint those perspectives impose. The constraints of each perspective are additive. For example, the constraints of higher rows affect the rows below. The constraints of lower rows can, but do not necessarily affect the higher rows. Understanding the requirements and constraints necessitates communication of knowledge and understanding from perspective to perspective. The Framework points the vertical direction for that communication between perspectives.<ref name="CIOC99"/> [[File:Simplification Zachman Enterprise Framework.jpg|thumb|420px|The VA Zachman Framework with an explanation of its rows.<ref name="VA02Pre">US Department of Veterans Affairs (2002) [http://www.va.gov/oirm/architecture/EA/theory/tutorial.ppt A Tutorial on the Zachman Architecture Framework]. Accessed 06 Dec 2008.</ref><ref>[[Bill Inmon]] called this image "A simple example of The Zachman Framework" in the article [http://www.b-eye-network.in/print/1962 John Zachman - One of the Best Architects I Know] Originally published 17 November 2005.</ref>]] In the 1997 Zachman Framework the rows are described as follows:<ref name="CIOC99"/> * ''Planner's View'' (Scope) - The first architectural sketch is a "[[bubble chart]]" or [[Venn diagram]], which depicts in gross terms the size, shape, partial relationships, and basic purpose of the final structure. It corresponds to an executive summary for a planner or investor who wants an overview or estimate of the scope of the system, what it would cost, and how it would relate to the general environment in which it will operate. * ''Owner's View'' ([[Enterprise modeling|Enterprise]] or [[Business Model]]) - Next are the architect's drawings that depict the final building from the perspective of the owner, who will have to live with it in the daily routines of business. They correspond to the enterprise (business) models, which constitute the designs of the business and show the business entities and processes and how they relate. * ''Designer's View'' (Information Systems Model) - The architect's plans are the translation of the drawings into detail requirements representations from the designer's perspective. They correspond to the system model designed by a systems analyst who must determine the data elements, logical process flows, and functions that represent business entities and processes. * ''Builder's View'' (Technology Model) - The contractor must redraw the architect's plans to represent the builder's perspective, with sufficient detail to understand the constraints of tools, technology, and materials. The builder's plans correspond to the technology models, which must adapt the information systems model to the details of the programming languages, input/output (I/O) devices, or other required supporting technology. * ''Subcontractor View'' (Detailed Specifications) - Subcontractors work from shop plans that specify the details of parts or subsections. These correspond to the detailed specifications that are given to programmers who code individual modules without being concerned with the overall context or structure of the system. Alternatively, they could represent the detailed requirements for various [[Commercial off-the-shelf|commercial-off-the-shelf (COTS)]], [[Government off-the-shelf|government off-the-shelf (GOTS)]], or components of modular systems software being procured and implemented rather than built. * ''Actual System View'' or The Functioning Enterprise === Focus or Columns === In summary, each perspective focuses attention on the same fundamental questions, then answers those questions from that viewpoint, creating different descriptive representations (i.e., models), which translate from higher to lower perspectives. The basic model for the focus (or product abstraction) remains constant. The basic model of each column is uniquely defined, yet related across and down the matrix.<ref name="CIOC99"/> In addition, the six categories of enterprise architecture components, and the underlying interrogatives that they answer, form the columns of the Zachman Framework and these are:<ref name="VA01"/> # The data description — What # The function description — How # The Network description — Where # The people description — Who # The time description — When # The motivation description — Why In Zachman’s opinion, the single factor that makes his framework unique is that each element on either axis of the matrix is explicitly distinguishable from all the other elements on that axis. The representations in each cell of the matrix are not merely successive levels of increasing detail, but actually are different representations — different in context, meaning, motivation, and use. Because each of the elements on either axis is explicitly different from the others, it is possible to define precisely what belongs in each cell.<ref name="VA01"/> === Models or Cells === The kinds of models or architectural descriptive representations are made explicit at the intersections of the rows and columns. An intersection is referred to as a cell. Because a cell is created by the intersection of a perspective and a focus, each is distinctive and unique. Since each cell is distinctive and unique, the contents of the cell are normalized and explicit per the perspective’s focus.<ref name="CIOC99"/> The cell descriptions in the table itself uses general language for a specific set of targets. Below the focus of each cell in this particular Zachman Framework is [[Explanation|explained]]: [[File:Zachman Framework Model.svg|thumb|500px|Current view of the Zachman Framework.]] ;Contextual # (Why) Goal List – primary high level organization goals # (How) Process List – list of all known processes # (What) Material List – list of all known organizational entities # (Who) Organizational Unit & Role List – list of all organization units, sub-units, and identified roles # (Where) Geographical Locations List – locations important to organization; can be large and small # (When) Event List – list of triggers and cycles important to organization ;Conceptual # (Why) Goal Relationship Model – identifies hierarchy of goals that support primary goals # (How) [[Process Model]] – provides process descriptions, input processes, output processes # (What) [[Entity-relationship model|Entity Relationship Model]] – 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 ;Logical # (Why) Rules Diagram – identifies and describes rules that apply constraints to processes and entities without regard to physical or technical implementation # (How) [[Process Diagram]] – identifies and describes process transitions expressed as verb-noun phrases without regard to physical or technical implementation # (What) [[Data model|Data Model Diagram]] – 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 # (When) [[Event chain diagram|Event Diagram]] – identifies and describes events related to each other in sequence, cycles occur within and between events, without regard to physical or technical implementation ;Physical # (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 ;Detailed Representation Eventually the cells with the detailed representation give Rules detail for (Why); Process detail for (How); Data detail for (What); Role detail for (Who); Location detail for (Where); and Event detail for (When). There is a sixth row in the current Zachman framework, but it is not used for enterprise architecture — while the enterprise is described by rows one to six, enterprise architecture uses only rows one to five, thus only five rows are shown here.<ref>{{cite web|url=http://www.zachmaninternational.com/index.php/ea-articles/100-the-zachman-framework-evolution|title=The Zachman Framework Evolution| publisher=Zachman International|date=April, 2009}}</ref> Since the product development (i.e., architectural artifact) in each cell or the problem solution embodied by the cell is the answer to a question from a perspective, typically, the models or descriptions are higher-level depictions or the surface answers of the cell. The refined models or designs supporting that answer are the detailed descriptions within the cell. Decomposition (i.e., drill down to greater levels of detail) takes place within each cell. If a cell is not made explicit (defined), it is implicit (undefined). If it is implicit, the risk of making assumptions about these cells exists. If the assumptions are valid, then time and money are saved. If, however, the assumptions are invalid, it is likely to increase costs and exceed the schedule for implementation.<ref name="CIOC99"/> === Framework set of rules === [[File:Example of Zachman Framework Rules.JPG|thumb|420px|Example of Zachman Framework Rules.]] The framework comes with a set of rules:<ref>Adapted from: Sowa, J.F. & J.A. Zachman, 1992, and Inmon, W.H, J.A. Zachman, & J.G. Geiger, 1997. [http://www.isqa.unomaha.edu/vanvliet/arch/ISA/isa.htm University of Omaha]</ref> * ''Rule 1 The columns have no order'' : The columns are interchangeable but cannot be reduced or created * ''Rule 2 Each column has a simple generic model'' : Every column can have its own meta-model * ''Rule 3 The basic model of each column must be unique'' : The basic model of each column, the relationship objects and the structure of it is unique. Each relationship object is interdependent but the representation objective is unique. * ''Rule 4 Each row describes a distinct, unique perspective'' : Each row describes the view of a particular business group and is unique to it. All rows are usually present in most hierarchical organization. * ''Rule 5 Each cell is unique'' : The combination of 2,3 & 4 must produce unique cells where each cell represents a particular case. Example: A2 represents business outputs as they represent what are to be eventually constructed. * ''Rule 6 The composite or integration of all cell models in one row constitutes a complete model from the perspective of that row'' : For the same reason as for not adding rows and columns, changing the names may change the fundamental logical structure of the Framework. * ''Rule 7 The logic is recursive'' : The logic is relational between two instances of the same entity. The framework is generic in that it can be used to classify the descriptive representations of any physical object as well as [[conceptual object]]s 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. === Flexibility in level of detail === One of the strengths of the Zachman Framework is that it explicitly shows a comprehensive set of [[view model|views]] that can be addressed by enterprise architecture.<ref name="GASLSJ03"/> Some feel that following this model completely can lead to too much emphasis on documentation, as artifacts would be needed for every one of the thirty cells in the framework. 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. Whereas 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''' and '''When''' columns. However, there is no escaping the '''Why''' column's importance as it provides the business drivers for all the other columns. == Applications and influences == Since the 1990s the Zachman Framework has been widely used as a means of providing structure for [[Information Engineering]]-style [[enterprise modeling]].<ref>Ian Graham (1995). ''Migrating to Object Technology: the semantic object modelling approach''. Addison-Wesley, ISBN 0201593890. p. 322.</ref> The Zachman Framework can be applied both in commercial companies and in government agencies. 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. <ref>Jay D. White (2007). ''Managing Information in the Public Sector''. p. 254.</ref> === Customization === Zachman Framework is applied in customized frameworks such as the [[TEAF]], build around the similar frameworks, the [[Treasury Enterprise Architecture Framework#TEAF Matrix of Views and Perspectives|TEAF matrix]]. <center><gallery> File:TEAF Matrix of Views and Perspectives.jpg|[[TEAF]] Matrix of Views and Perspectives.

This methodology required them to define all aspects of the VA enterprise from a business process, data, technical, location, personnel, and requirements perspective. The next step in implementing the Zachman 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.

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.<ref>[http://www.va.gov/oit/ea/4_3/process/modeling/metamodel.html Meta-Model Cell Details] Accessed 25 Dec 2009</ref> [[File:VA EA Meta-Model Cell Details Enlarged.jpg|thumb|600px|center|VA EA Meta-Model Cell Details Enlarged.]] This diagram<ref>This diagram is the exclusive work of Albin Martin Zuech of Annapolis Maryland, who placed it in the public domain in 2001. Al Zuech maintains the original [[visio]] diagram in numerous stages of its development between 2000 and present. Al Zuech was the Director, Enterprise Architecture Service at the Department of Veterans Affairs from 2001 until 2007.</ref> has been incorporated within the VA-EA to provide a symbolic representation of the [[metamodel]] that VA used, to describe the One-VA Enterprise Architecture and to build an EA Repository without the use of Commercial EA Repository Software. The One-VA EA repository was developed using an [[object oriented database]] within the Caliber-RM Software Product. 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 that was available in early 2003. The personal motivation in selecting this tool was two-fold: # none of the commercial repository tools that were available at that time provided a true Zachman Framework representation of models and relationships; and # the available commercial tools were highly proprietary and made it difficult to incorporate best-of-breed tools and representations from other vendors or form open sources. This diagram emphasizes several important interpretations of the Zachman Framework and its adaptation to information technology [[investment management]]. # Progressing through the rows from top to bottom, one can trace-out the [[Systems Development Life Cycle]] (SDLC) which is a de facto standard across the Information Industry; # The diagram emphasizes the importance of the often-neglected Zachman Row-Six (the Integrated, Operational Enterprise View). Representations in Mr. Zuech’s interpretation of Zachman row-six consist, largely, of measurable service improvements and cost savings/avoidance that result from the business process and technology innovations that were developed across rows two through five. Row-six provides measured [[Return on Investment]] for Individual Projects and, potentially, for the entire [[investment portfolio]]. Without row-six the Zachman Framework only identifies sunk-cost – the row-six ROI permits the framework to measure benefits and to be used in a continuous improvement process, capturing best practices and applying them back through row-two. == See also == * [[Data model]] * [[Enterprise Architecture framework]] * [[Enterprise Architecture Planning]] * [[FDIC Enterprise Architecture Framework]] * [[View model]] ==References== {{reflist}} == External links == {{Commonscat|Zachman Framework}} * [http://www.zachmaninternational.com/index.php/the-zachman-framework The Zachman Framework: The Official Concise Definition] by John A.
