The Zachman framework provides a means of classifying an organization's architecture. Proceedings of the 5th International Command and Control Research and Technology Symposium, Canberra: CCRP Press, pp. The framework consists of 36 cells, each focusing on the enterprises perspective. A. The Zachman Framework is more focused on defining and organizing the data than it is on designing and implementing processes. In the Select Diagram window, select the diagram (s) to add to cell and click OK. Yet, Zachman continued to emphatically promote his framework and insistently inquired: Why would anyone think that the descriptive representations for enterprises are going to be any different from the descriptive representations of anything else that has ever been created?8 (page 41)Moreover, he relentlessly argued for producing excruciatingly detailed descriptions and even went further to guarantee that such formal, engineering-style drawings are necessary for organisations: Some day, I guarantee you, you are going to wish you had every one of the models identified by the [Zachman Framework] made explicit, every one of them made explicit enterprise-wide, all the models integrated horizontally across every row, all the models integrated vertically down every column and all the models made explicit at excruciating levels of detail9 (page 9). A Comparison of the Top Four Enterprise Architecture Frameworks (click to view larger image). Specifically, all of them assume that whatever is promised by EA frameworks is true, i.e. The Zachman Framework is a well-known method for organizing and categorizing a company's data architecture. The Zachman framework describes competitive forces in an industry. The Gartner Framework . [] The end result is normally incomprehensible to a business-oriented audience and is harder to trace to the business strategy. The Zachman framework's approach to EA management is model-based. Physical considers how software is mapped to hardware. Gartner alone issued nearly a dozen of several hundred dollars-worth reports with its advice on how to analyse, choose and deal with EA frameworks properly3. 4 Zachman, J. This uses rows to represent different perspectives or viewpoints on enterprise architecture (e.g., strategic planning vs. operations). The Zachman Framework for Enterprise Architecture, sometimes simply referred to as the "Zachman Framework", has become a de facto standard for classifying the artifacts developed in enterprise architecture. The ________ department usually manages the computers, computer centres, networks, and. Technician Perspective a programmer given instructions Implementation Governance assigning governance functions for different stages of architecture deployment It is attributed to IBM professional John Zachman, as presented in the article "A Framework for Information Systems Architecture" published in the IBM Systems Journal in 1987. As companies increasingly dive into the complexities of Service-Oriented Architecture (SOA), they need to consider an expanding set of criteria for what must go into the architectures they design. John Zachman was an IT pioneer who understood the problems facing IT-driven businesses. BSP, Method/1 and Information Engineering) that discredited themselves long ago and, therefore, offers essentially nothing new and simply cannot work successfully in practice23. For example, lets look at the box at the bottom of the column under Time, which represents the temporal context of the business, for example, the master schedule for the entire organization. What is Enterprise Architecture (EA)? Notice that the Zachman Framework covers the gamut from purely business models, like business strategy, business locations, and the organizational hierarchy, all the way to deeply technical models, including detailed network, security, and data specifications. Lenovo Late Night I.T. Before discussing methodology vs framework, let us look into the meaning of framework and methodology. 278-306. Some companies claim to use the Framework to organize their corporate data, and it is often cited as an example of an enterprise architecture. The Zachman Framework goes beyond IT. As a result, the Framework indicates the next iteration of SOA beyond Application Architecture should deal with the eight neighboring squares, as shown in the figure below: Leveraging Zachman to extend SOA to the Enterprise customer demand, may involve this . LOKASI Enterprise is a geospatial software that can be customized to support better corporate . Similarly to FEAF and DoDAF, TOGAF follows fundamentally the same mechanistic step-by-step logic as all the previous architecture planning methodologies (e.g. After gathering insight from renowned authorities in the field, he made a few final changes to produce an image that encapsulates The Zachman Framework like never before. 81-110. The fact model incorporates consumers, suppliers, products, and services. On the 'Model Patterns' tab, click on the <name> Perspective button and select 'Enterprise Architecture > Zachman' from the list. Enterprise architecture frameworks are valuable for planning and visualization. 10Hobbs, G. (2012) EAM Governance and Organisation, In: Ahlemann, F., Stettiner, E., Messerschmidt, M. and Legner, C. Kick-start a career in IT, whether you're starting out or looking for a career change. 445-461. It is the sum total of all of these views that together comprises EA. However, the official report to congressional committees concluded that the developed architecture deliverables turned out largely useless: The products that it has produced do not provide sufficient content and utility to effectively guide and constrain ongoing and planned systems investments. Due to its extensiveness, the framework is highly adaptable, and it nurtures agility and collaboration. To be a company that is far superior to its competitor, the company can implement Information Systems (IS) or Information Technology (IT) that is in (PDF) Redesign the Forwarding Company's Business Processes Using the Zachman Framework | Bernadus Gunawan - Academia.edu 1, pp. The Open Group Architecture Framework (TOGAF) is a framework used for enterprise architecture to improve business efficiency and presents an approach for designing, planning, executing, and. A comparison of the top four EA frameworks is briefly summarised in Figure 1. In particular, DoD intended to create a comprehensive architecture for its business mission area consisting of almost the full set of 26 products prescribed by DoDAF19 (pages 40-41)(this case, by the way, clearly demonstrates that EA frameworks were originally designed to be implemented literally as is, not merely as flexible toolkits for architecture, as many people would argue today). The Zachman framework is a comprehensive and well-defined matrix tool for Enterprise Architecture. This will be specific to your IT project or concern and might change when applied to another product or service. Instead, the Framework represents a best case, providing guidance for enterprise architects to tackle different aspects of their organization as the business needs dictate. As a result of Zachmans brilliant and persistent promotional efforts, what we have today is a purely symbolic taxonomy, which is claimed to be fundamental, but is apparently based on inappropriate and confusing assumptions, cannot classify real EA artifacts, has no demonstrated examples of its practical application, no use cases in organisations, no implications for EA practitioners anddoes not add any theoretical or practical value to the EA discipline, as discussed earlier. It is a classification scheme for descriptive representations of the enterprise. In addition, columns represent artifacts created during system development (e.g., requirements specifications or process flows). The Zachman Framework points out that all such views and many more are every bit as important as all the others in obtaining a complete view of the workings of the enterprise. It offers structural connections into any aspect of an enterprise. Weve already discussed the role of enterprise architects in businessand now well highlight the tools and approaches they put to work in planning and visualizing the transformation. Some people, after all, construe SOA narrowly as a form of application architecture, while other people think of SOA more broadly as EA. Discussion. The Zachman Framework, originally authored by John Zachman in the 1980s at IBM, has since become widely adapted by IT organizations as a framework for identifying and disciplining the various perspectives involved in an enterprise architecture. Their broad range of skills along with their ability to find a common language with both stakeholders and IT experts allow them to guide a company to its desired state. There is a lot of interest currently in the Zachman Framework. As TOGAF was first developed 25 years ago, its framework has not been transformed. Here are the main concerns surrounding the use of enterprise architecture frameworks today. Researchers need to be able to trust that their data was gathered reliably to trust their studys findings. Methodology refers to the systematic, logical approach to doing something. To say it has a following is an understatement. 23Kotusev, S. (2018) TOGAF: Just the Next Fad That Turned into a New Religion, In: Smith, K. L. Today, it is widely advertised as the fundamental structure or even ontology for enterprise architecture, whose role in the EA discipline is equivalent to the role of the periodic table of elements in chemistry. To navigate around the document: In the main Contents frame at the top of the page, click the relevant hyperlink (Part I, Part II, etc.) Where? 19, No. 1, pp. In this version, a notable improvement is transitioning from I/S terminology to more business-oriented terms, which has been instrumental in getting the framework noticed by General Management. 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). Precisely the same conclusions have also been echoed several years later in another official report: Even though DoD has spent more than 10 years and at least $379 million on its business enterprise architecture, its ability to use the architecture to guide and constrain investments has been limited20 (page ii). Companies can use LOKASi Enterprise to deal with those problems. The Zachman Framework goes beyond IT. Instead, its considered an ontology or schema to help organize enterprise architecture artifacts such as documents, specifications and models. John consulted with influential members of the academic and consulting spheres, eminent data and process modeling leaders, veteran IT distributors, Business Rule connoisseurs, and top tool vendors for their feedback. Enterprise Perspective an operational system itself, What? Finally, A good methodology will help you achieve your goals efficiently and effectively.MethodologyFrameworkIt is a systematic approach to solving a problem.It is a visual or structural approach to solving problems. Here we listed some of the familiar companies. 43, No. Avoid altering the names of your rows or columns. The iterative approach to SOA offers enterprise architects an architectural roadmap that tells them where to start, whats important, and which way to go. Identifying the target variable is the first step in applying binary classification for assortment. However, research reports from some organisations that acted in line with his advice indicate that their EA practices resulted in dramatic failures with multimillion dollar consequences10 (page 85) and anecdotal evidence suggests that similar experiences were rather typical across the industry: Most of us have heard John Zachmans often-quoted remark: Someday you are going to wish you had all these models made explicit, enterprise-wide, horizontally and vertically integrated, at an excruciating level of detail. The SIM Guide to Enterprise Architecture, Boca Raton, FL: CRC Press, pp. They are. - Details, Frameworks, and Tools, What is TOGAF Framework? 276-292. During the four-day hands-on modeling workshop you will look at real life examples of the Zachman Framework and learn how to build and implement primitive models. Taking this remark too literally has caused too many EA teams to lock themselves in their ivory towers, snowed under by hundreds of models that no one is able to keep up to date11 (page 10). Enterprise architecture considers organizations complex systems. In practice, the ZF summarizes a collection of perspectives based upon an architecture. It can be used to help make decisions by providing a structured way of looking at a problem. Categories are organized in six rows by six columns, forming a two-dimensional matrix with 36 cells that helps you visualize the topic, problem or product. These frameworks allegedly offer the necessary guidance for practicing enterprise architecture and addressing the problem of business and IT alignment in organisations. 3Lapkin, A. and Weiss, D. (2008) Ten Criteria for Selecting an Enterprise Architecture Framework (#G00163673), Stamford, CT: Gartner. According to John Zachman, his framework allows you to create organizations or transform businesses over time. Seamless security integration and alignment with other frameworks including TOGAF, ITIL, Zachman, DoDAF; Business-driven, traceable toolkits for modelling and deploying security standards and references such . whether EA frameworks in fact delivered on their promises and what their real value is). (ed.) For SOA to be the architecture that enables such broad agility and change in organizations, its essential for architects to eventually apply the entire Zachman Framework to SOA. The Zachman Framework initially emerged in the 1980s as a two-dimensional 30-cell taxonomy for architectural descriptions4. Zachman laid out the overall map, but didnt 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. For this reason, all the extant analyses of EA frameworks essentially concentrate only on ample promises given by these frameworks and take their promises for granted, but never question them or analyse whether, or to what extent, these promises have actually been delivered. A quick examination of the Zachman Framework, however, will suggest that business processes are not central to Zachman's conception. 15Periasamy, K. P. (1994) Development and Usage of Information Architecture: A Management Perspective, PhD Thesis: University of Oxford, UK. The TOGAF document set is designed for use with frames. If you are successful with rules 2, 3 and 4, you should have a matrix where each cell is unique. For example, the academic literature offers tens of papers devoted to analysing, comparing and formulating selection criteria for EA frameworks2. (1996) Concepts of the Framework for Enterprise Architecture: Background, Description and Utility, Monument, CO: Zachman International. represents genuine best practices and valid reference models that proved helpful in some organisations and can be beneficial to other companies willing to practice enterprise architecture. Development focuses on software modules, packages, and environments used The Zachman Framework offers a model-based approach that: Specifies the deliverables 292786, Continuing professional development (CPD), does not add any theoretical or practical value to the EA discipline, did not coin the term enterprise architecture, absurdness of TOGAF is already widely acknowledged, more reasonable planning approaches are followed instead, The Practice of Enterprise Architecture: A Modern Approach to Business and IT Alignment, articles and other materials on enterprise architecture. Even with the ZIFA logo on the right of their 2002 representation, Intervista maintained its positional dominance in advertising. Rhetorically, FEAF was based on the pioneering ideas of John Zachman and Steven Spewak, who were regarded as two of many recognised leaders in architecture conceptualisation and enterprise architecture planning12 (page 19). The Open Group Architecture Framework or TOGAF has been developed by more than 300 enterprise architects from leading companies including Dell, Cognizant, and Microsoft. However, the level of saturation is high, as they manage. Existing EA frameworks are covered in many mainstream sources. Now, well dive deeper into functionalities and use opportunities for each framework. Furthermore, the very genre of musing on frameworks is extremely popular among various EA writers. In light of the abundant previous negative research findings regarding formal architecture methodologies13, 14, 15, the failure of FEAF can be viewed as a natural, perfectly predictable and even the only possible outcome. Zachman proposed the Zachman Framework for Enterprise Architecture (ZFEA), a descriptive, holistic representation of an enterprise for the purposes of providing insights and understanding. Svyatoslav Kotusev is an independent researcher, educator and consultant. The tool has a common vocabulary and is meant to support all levels of architecture for enterprises both large and small. Enterprise architects use stereotypes, tagged values, and constraints to tailor the language to specific environments thus ensuring that the finished model will address corporate-specific requirements. The fundamental flaw in the underlying analogy between engineering products and information systems exploited by Zachman was spotted long ago, besides many other people, even by his colleagues from IBM7. The Zachman Framework provides a holistic view of an enterprise and primarily integrates organizational and information-related aspects. The way an enterprise architect uses the Framework is as a guide for the models their team might use to represent the elements of the architecture implementation. Zachman offers the most holistic approach to implement the EA framework into business models. In 1987, this framework for information systems architecture was published in the IBM system Journal. The Zachman Framework is an enterprise architecture framework that provides a formalized view of an enterprise across two dimensions. As one of the DoD reports neatly summarised, hundreds of millions of dollars had been spent on a business enterprise architecture (BEA) that had limited use21 (pages 1-2). In 1984, a framework for information system architecture was developed by John A Zachman. UML models allow businesses to develop a set of processes and use cases to visualize an enterprise architecture overall and each system within it. Namely, Zachman speculated that an analogous set of architectural representations is likely to be produced during the process of building any complex engineering product, including an information system4 (page 281). Some people will have a more data-centric perspective, while others focus on the management hierarchy; some individuals live among the nitty gritty details, while others seek the big picture. TOGAF Is Not an EA Framework: The Inconvenient Pragmatic Truth, Great Notley, UK: Pragmatic EA Ltd, pp. So, what do we know about popular EA frameworks besides these speculations? The Zachman Framework, developed by John Zachman, is an enterprise ontology and is a fundamental structure for Enterprise Architecture that provides a formal and structured way of viewing and defining an enterprise. Each domain is further divided into sub-domains. Unsurprisingly, FEAF failed as well, and failed spectacularly: Enterprise architecture within the Federal Government hasnt been working, and far more often than not hasnt delivered useful results. The latest insights, ideas and perspectives. Copyright 2023 IDG Communications, Inc. to load the Contents List for that Part of the TOGAF document into the Secondary Index frame in the left margin. It provides a structure for organizing information about an organization and its business processes to make better decisions about designing, implementing, and improving those processes. 14Lederer, A. L. and Sethi, V. (1988) The Implementation of Strategic Information Systems Planning Methodologies, MIS Quarterly, Vol. Numerous consultancies, vendors and gurus tout EA frameworks for their own pecuniary purposes, regardless of their detrimental effects on the EA discipline. All of these companies found the Zachman Framework a great tool that creates knowledge and clarity, and decision-making and analysis aid (Singer, 2007). During The Open Group's 2015 San Diego event, John gave the morning's keynote address. (2010) Architecture Is Architecture Is Architecture, In: Kappelman, L. A. The Zachman Framework helps companies organize and prioritize the various perspectives on EA, and this organization and prioritization applies just as well when the EA is SOA. 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). Now, in virtually all cases, TOGAF is viewed merely as a label and used purely declaratively - its prescriptions are simply ignored and other, more reasonable planning approaches are followed instead. Although originally the framework was conceived for individual information systems, in the late 1990s it was readily elevated to the enterprise level and repositioned as the framework for enterprise architecture, even without any noticeable modifications of its structure6. The most impressive enhancement of this version is the utilization of gradient color banding across the Rows and down the Columns. However, despite the abundance and variety of the available frameworks analyses, these analyses have one critically important feature in common: all these analyses are perfectly speculativein nature. An example of an Activity Diagram 80% of Global 50 companies and 60% of Fortune 500 companies use the TOGAF framework. Contact Us Furthermore, SOA impacts the way that organizations share and represent information (via semantic and logical data models) as well as how the network deals with applications. Each row describes a distinct, unique perspective. Learn howand get unstoppable. Click here for a larger version. Add a new Zachman Framework model to the project. improved clarity and communication about systems and processes; better decision-making due to a more holistic view of the organization; increased efficiency due to standardized methods; and. Select the 'Zachman Framework' pattern. 1, pp. The Zachman Certified - Enterprise Architect Program After countless discoveries about the science of Enterprise Architecture from the Zachman Framework 3.0; and due to unprecedented demand, we are proud to offer the Zachman Certified - Enterprise Architect program. The columns of a Zachman Framework template outline the fundamental questions surrounding the architecture in question (who, what, where, and so on), while the rows represent the perspectives of each type of stakeholder involved in the project. The fifth view Scenarios or Use Cases represents the high-level view of the whole system and illustrates an architectures consistency and validity. At the present moment, it would arguably be fair to say that the broad interest in the Zachman Framework has already faded away and within the next few years it is likely to be forgotten by the EA community due to its inexplicable practical utility. 5Spewak, S. H. and Hill, S. C. (1992)Enterprise Architecture Planning: Developing a Blueprint for Data, Applications and Technology, New York, NY: Wiley. Consequently, similarly to early architecture planning methodologies, FEAF is based on the nave assumption that the long-term target state for the whole organisation can be defined by a dedicated group of planners, described in detail via numerous formal diagrams and relationship matrices and then implemented as planned.
