Decomposition (i.e., drill down to greater levels of detail) takes place within each cell. 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. [13] 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. This diagram is the exclusive work of Albin Martin Zuech of Annapolis Maryland, who placed it in the public domain in 2001. Examples: Zachman Framework for Enterprise Architecture, TOGAF, DODAF, MODAF, FEAF Based on the semantic definitions (above) that most closely reflect the usage of the term framework in reference to EA, the key elements are ‘structure,’ ‘simplifying a complex entity,’ and ‘model.’ The constraints of each perspective are additive. 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. In the 1992 article "Extending and Formalizing the Framework for Information Systems Architecture" John F. Sowa and John Zachman present the framework and its recent extensions and show how it can be formalized in the notation of conceptual graphs. The list of organizations that has and are using the Zachman Framework can go on and on listing larger companies like Bank of America, Health Canada, General Motors, and Volkswagen (Singer, 2007). related to those items. and the Zachman framework (1987). 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. a two-dimensional schema, used to organize the detailed representations of the enterprise. 1. planned to implement an enterprise architecture fully based on the Zachman Framework. 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 Who, When and Why columns were brought into public view, the notion of the four levels of metaframeworks and a depiction of integration associations across the perspectives were all outlined in the paper. The refined models or designs supporting that answer are the detailed descriptions within the cell. [citation needed], 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. The Zachman Framework summarizes a collection of perspectives involved in enterprise architecture. The diagram emphasizes the importance of the often-neglected Zachman Row-Six (the Integrated, Operational Enterprise View). The basic model of each column is uniquely defined, yet related across and down the matrix. [26] 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:[24], 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. [26], The framework comes with a set of rules:[30]. The framework does not define a methodology for an architecture. The framework provides six increasingly detailed views or levels of abstraction from six different perspectives. If, however, the assumptions are invalid, it is likely to increase costs and exceed the schedule for implementation. Zachmanフレームワークは、ビュー・モデル (View model)で高度に構造化された方法を提供するエンタープライズアーキテクチャフレームワークである。, それは、6つのコミュニケーション(何を、どこで、なぜ、誰が、及びどのように)の質問と6つの変換の具体化 (Reification)に対応する行が交差する2次元の分類から成る。[1], Zachmanフレームワークは、それが記述する情報を収集し、管理し、使用するための特定な手法やプロセスに欠けることから、方法論ではない。[2] そのフレームワークは、1980年代にIBMにてその概念を最初に開発した、その創作者John Zachmanによって後に命名された。それから数回改訂がされている。[3], Zachmanの『フレームワーク』は、成果物はだれのため(例えば、事業オーナーと構築者)とどんな特定課題(例えば、データ及び機能性)が取り扱われるかの両方の記事にかかる、仕組的生成物(別の言葉で、設計文書、仕様、及びモデル)のための分類体系 (Taxonomy)である。[4]. [16] 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. This diagram[40] has been incorporated within the VA-EA to provide a symbolic representation of the metamodel it used, to describe the One-VA Enterprise Architecture and to build an EA Repository without the use of Commercial EA Repository Software. Pete Sawyer, Barbara Paech, Patrick Heymans (2007). The Zachman Framework is a schema - the intersection between two historical classifications that have been in use for literally thousands of years. Caliber-RM is intended to be used as a software configuration management tool; not as an EA repository.

Gauss, Assistant Secretary for Information and Technology, Department of Veterans Affairs, "Why Doesn’t the Federal Enterprise Architecture Work? The first EA frameworks appeared including the PRISM framework in 1986 (which was sponsored by IBM among other companies), the Zachman Framework in 1987 and the NIST EA model in 1989. [26], Each perspective must take into account the requirements of the other perspectives and the restraint those perspectives impose. An intersection is referred to as a cell. 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 2003. 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. [29], 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. Further modeling by mapping between columns in the framework identifies gaps in the documented state of the organization. Zachman defines 7 rules for using his framework. 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.[32]. [16], The Information Systems Architecture is designed to be a classification schema for organizing architecture models. In: Vladan Jovanovic, Stevan Mrdalj & Adrian Gardiner (2006). Using the Zachman Framework Get started with the Zachman Framework, learning about the model structure, templates, diagram types and more. Zachman laid out the overall map, but didn’t provide a guide for prioritizing your route through the Framework, or a way for determining which parts of the Framework are more important to you than others. In 1982 Zachman[14] 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. The Zachman Framework for Enterprise Architecture: ... It’s designed for the U.S. government, but it can also be applied to private companies that want to use the framework. The Zachman Framework 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 hard job then followed to de-conflict the data definitions and resolve duplicative implementations of the same business function. If a cell is not made explicit (defined), it is implicit (undefined). Leveraging the Zachman Framework Implementation Using Action-Research Methodology - A Case Study: Aligning the Enterprise Architecture and the … Use of the Although the Zachman Framework applies to enterprises, the Framework itself is generic. The framework is purely speculative, non-empirical and based only on the conceptual argument that the "equivalency [between the architectural representations of the manufacturing and construction industries] would strengthen the argument that an analogous set of architectural representations is, Practical feedback shows that the general idea of creating comprehensive descriptions of enterprises as suggested by the Zachman Framework is unrealistic, In 2004 John Zachman admitted that the framework is theoretical and has never been fully implemented: "If you ask who is successfully implementing the whole framework, the answer is nobody that we know of yet", There are no detailed examples demonstrating the successful practical application of the framework, EA practitioner Stanley Gaver argues that "the analogy to classical architecture first made by John Zachman is faulty and incomplete", Jason Bloomberg argues that "enterprise isn’t an ordinary system like a machine or a building, and can’t be architected or engineered as such", A detailed scrutiny demonstrates that the Zachman Framework is actually based only on purely speculative arguments, promoted with fictional promises, has no practical use cases and, from the historical perspective, didn't introduce any innovative ideas missing before, This page was last edited on 14 May 2020, at 18:25. Hervé Panetto, Salah Baïna, Gérard Morel (2007). This framework suggests a logical structure for categorizing, organizing and describing a detailed illustration of a company. Geiger, 1997. VA Enterprise Architecture Innovation Team (2001). The next step in implementing the Zachman methodology has been to define all functions related to each business process and identify associated data elements. The basic model for the focus (or product abstraction) remains constant. It has a matrix representation, with six rows (scope contexts, business concepts, system logic, technology physics, component assemblies, operations classes) and six columns (what, how, where, who, when, why). The cell descriptions in the table itself uses general language for a specific set of targets. This diagram[40] 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. [32]. Mapping the IEC 62264 models onto the Zachman framework for analysing products information traceability. 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. Decomposition (i.e., drill down to greater levels of detail) takes place within each cell. [26] 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:[24], 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. Caliber-RM is intended to be used as a software configuration management tool; not as an EA repository. Vladan Jovanovic et all (2006) presents a Zachman Cube, an extended of the Zachman Framework into a multidimensional Zachman's Cube. 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. These perspectives are represented in a two-dimensional matrix that defines along the rows the type of stakeholders and with the columns the aspects of the architecture. Unfortunately, we have few examples available in the public domain illustrating a complete set of models that comply with the Zachman framework. Since the 1990s several extended frameworks have been proposed, such as: 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 uses the method of taxonomy to organize a massive variety of documents and materials into categories that suit them. This article fills a complete framework for the game of Baseball. 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.[17]. This diagram is the exclusive work of Albin Martin Zuech of Annapolis Maryland, who placed it in the public domain in 2001. These 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. 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. In 2008 Zachman Enterprise introduced the Zachman Framework: The Official Concise Definition as a new Zachman Framework standard. Getting Zachman Certified is dollar-for-dollar the smartest investment an architect, any architect, can make. This VA Zachman Framework Portal is still in use as a reference model for example in the determination of EA information collected from various business and project source documents. While the Zachman Framework is widely discussed, its practical value has been questioned: This criticism suggests that the Zachman Framework can hardly reflect actual best practice in EA. As a business analyst, you are likely to be particularly concerned with the top 3 levels. [38], Integrated Process Flow for VA IT Projects (2001), A Tutorial on the Zachman Architecture Framework. In 2008 Zachman Enterprise introduced the Zachman Framework: The Official Concise Definition as a new Zachman Framework standard. John Baschab, Jon Piot, Nicholas G. Carr (2007). 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. Not … TEAF Work Products for EA Direction, Description, and Accomplishment. If you can answer all of these six questions, then you can derive answers to any other questions about the subject or object. [3], The framework is named after its creator John Zachman, who first developed the concept in the 1980s at IBM. Zachman Framework is also used as a framework to describe standards, for example standards for healthcare and healthcare information system. Curiously, each proponent seems to conceive his own particular set of reasons for liking it. It is a comprehensive, logical structure for the descriptive representations (i.e., models or design artefacts) of any complex object, and it 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.[39]. The basic model for the focus (or product abstraction) remains constant. Zachman, & J.G. For example, the constraints of higher rows affect the rows below. Another application of the Zachman Framework is as reference model for other enterprise architectures, see for example these four: EAP mapped to the Zachman Framework, 1999. The ontology is a two dimensional classification schema that reflects the intersection between two historical classifications. 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. All of these companies found the Zachman Framework a great tool that creates knowledge and clarity, and decision-making and analysis aid (Singer, 2007). An upper row or perspective does not necessarily have a more comprehensive understanding of the whole than a lower perspective. Even in the current economic down-turn, savvy companies are turning to EA and The Zachman Framework for help. Zachman, however, indicates that only the facts needed to solve the problem under analysis need be populated. Zachman, 1992, and Inmon, W.H, J.A. This methodology required them to define all aspects of the VA enterprise from a business process, data, technical, location, personnel, and requirements perspective. The Chief Information Officers Council (1999). 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. [24], It allows different people to look at the same thing from different perspectives. Axis 1 - The What, How, When, Who, Where, and … There is a lot of interest currently in the Zachman Framework. The Framework points the vertical direction for that communication between perspectives. It helps me gain perspective to helicopter up, as well as when I … The basic model of each column is uniquely defined, yet related across and down the matrix. Adapted from: Sowa, J.F. By this test, the Zachman Framework Architecture is a masterpiece. For example, the constraints of higher rows affect the rows below. 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. Since the 1990s the Zachman Framework has been widely used as a means of providing structure for information technology engineering-style enterprise modeling. Because a cell is created by the intersection of a perspective and a focus, each is distinctive and unique. [14], In the 1987 article "A Framework for Information Systems Architecture"[15] 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. The framework provides six different transformations of an abstract idea (not increasing in detail, but transforming) from six different perspectives. In the 1992 article "Extending and Formalizing the Framework for Information Systems Architecture" John F. Sowa and John Zachman present the framework and its recent extensions and show how it can be formalized in the notation of conceptual graphs. The Zachman Framework isn’t exactly a methodology, at least not in the way most IT management frameworks are, mainly because it doesn’t offer specific processes for handling data. It was developed using an object oriented database within the Caliber-RM Software Product. Somewhere in between the VA Zachman Framework Portal was constructed. The Zachman framework further defines these six elements at 6 levels (rows), ranging from the conceptual view to the technical you. VA Enterprise Architecture Innovation Team (2001). The first is the fundamentals of communication found in the primitive interrogatives: What, How, When, Who, Where, and Why. 2.3 Zachman Framework Zachman Framework was surveyed to be the most popular [18]. SABSA uses Zachman’s six questions that we’… "Process-Based Planning in Information Resource Management". [31] The Zachman Framework can be applied both in commercial companies and in government agencies. 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".[20]. 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. Abstract - An effective Enterprise Architecture framework can help an organization or an enterprise deal with the ever-changing business and technology needs and Zachman Framework is one such Enterprise Architecture framework. It offers structural connections into any aspect of an enterprise. [38], Integrated Process Flow for VA IT Projects (2001), A Tutorial on the Zachman Architecture Framework. The framework considers who is affected by the artifact, such as the business owner, and w… In 1982 Zachman[14] 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. The example Enterprise Architect model for the Zachman Framework UML profiles (Toolbox pages) for use within specific Zachman Framework cells カテゴリ「Zachman Framework」にあるメディア このカテゴリに属する 39 個のファイルのうち、 39 個を表示しています。 このページの最終更新日時は 2018年7月10日 (火) 22:26 です。 ファイルは、それぞれの説明文書のページで指定されたライセンスのもとで利用できます。 The Zachman Framework for Enterprise Architectures The first thing we need to understand about the Zachman Framework is that it isn't a framework. This VA Zachman Framework Portal is still in use as a reference model for example in the determination of EA information collected from various business and project source documents. Vladan Jovanovic et all (2006) presents a Zachman Cube, an extended of the Zachman Framework into a multidimensional Zachman’s Cube. Enterprise Security Planning using Zachman Framework: Designer’s Perspective . Each cell of the framework contains such a series of standards for healthcare and healthcare information system.[33]. Understanding the requirements and constraints necessitates communication of knowledge and understanding from perspective to perspective. This organization helps ensure Zachman framework: The Zachman framework is a logical structure intended to provide a comprehensive representation of an information technology enterprise. Rule 2: Each column has a simple generic … The second is derived from reification, the transformation of an abstract idea into an instantiation that was initially po… [13] Zachman, John A. The cell descriptions are taken directly from version 3.0 of the Zachman Framework. TEAF Work Products for EA Direction, Description, and Accomplishment. The diagram emphasizes the importance of the often-neglected Zachman Row-Six (the Integrated, Operational Enterprise View).
