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). Furthermore, even Steven Spewak himself admitted that the vast majority of enterprises that undertake Enterprise Architecture Planning are not successful5 (page 19). |. But which one is right for your business? TOGAF and Zachman do not conflict with each other, but rather go hand in hand: The Zachman Framework is a high-level metamodel that provides a structure. 16Gaver, S. B. The inherent flaw from the beginning was the lack of a standard framework or methodology that allows the architecture to be inserted into the decision making process18 (page 2). A key element of this framework is that it avoids all redundancies in the final two-dimensional matrix. SABSA closely follows the Zachman Framework and is adapted to a security focus. . 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. If you are successful with rules 2, 3 and 4, you should have a matrix where each cell is unique. The Zachman Framework has come a long way in three decades and so in honor of Mr. Zachman's work, there is a celebration at the upcoming Enterprise Data World 2012 Conference. For many people, the very notion of enterprise architecture (EA) is closely associated with EA frameworks, if not entirely synonymous to them, writes Svyatoslav Kotusev, Enterprise Architecture researcher. 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). The Zachman Framework provides a holistic view of an enterprise and primarily integrates organizational and information-related aspects. Almost 30 years after the creation of the Zachman Framework the oldest of the currently used EA tools a question has arisen: Do frameworks bring any value or do they cause harm? As a result, it provides answers to both questions (What does it do?) and (How does it do it?). Svyatoslav Kotusev is an independent researcher, educator and consultant. the translation of business goals and strategies into specific means. 41, No. Those architects following ADM steps more or less closely and developing at least half of all the deliverables prescribed by ACF will inevitably face analogous problems, experience disappointment and eventually abandon TOGAF as a practical guidance: After an intensive phase of familiarisation and an initial workshop, where TOGAF was presented to the involved stakeholders, we decided: Thanks, too complicated for us25 (page 14). How? When? Here we listed some of the familiar companies. Last but not least, the Gartner Framework is a common EA framework created in 1985 which is neither a taxonomy (like Zachman), nor a process (like TOGAF), nor a complete methodology (FEA); instead, it is defined as a practice by one of the leading IT research and advisory companies in the world: Gartner, Inc.. Gartner, Inc., employs well-qualified specialists in the IT . Some people, after all, construe SOA narrowly as a form of application architecture, while other people think of SOA more broadly as EA. 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). It is a logical structure for classifying and organizing the design artifacts of an enterprise that are significant to its management. DoDAF defines the views that should be covered in architecture, specific products that should be created to describe them and the steps that should be followed to develop these deliverables. In 2003, some ZIFA members wanted more satisfaction with the Intervista-institute version of the framework. 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. The Zachman Framework named after the man himself, John Zachman is considered to be the pioneer and the first to propose the concept of EA. 22TOGAF (2018) TOGAF Version 9.2 (#C182), Reading, UK: The Open Group. 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 framework is one among top 4 and enjoys a good . The ' Model Wizard ' view displays. Zachman offers the most holistic approach to implement the EA framework into business models. we emphasize that Service Orientation (SO) is a business movement, where organizations are better able to leverage information technology (IT) in agile ways to meet ever-changing business needs. In 2011, A new version of the Zachman framework arrived after some years of re-structuring in Zachman International. In the center of the process you can find Requirements Management the stage reflecting the ongoing process of aligning changes and requirements of each phase. So, remember, that despite its popularity, TOGAF is not a cure-all and should be used as a guide rather than an actionable plan. A quick examination of the Zachman Framework, however, will suggest that business processes are not central to Zachman's conception. 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. Lets quickly compare the most popular frameworks. The Zachman Framework is a well-known method for organizing and categorizing a company's data architecture. The framework was proposed by John Zachman, at that time a marketing specialist at IBM, as part of his attempts 'merely to improve on the planning methodologies to follow BSP' 5 (page xvi) (BSP was one of the earlier IBM's information systems planning methodologies that he promoted since the 1970s). This view is relevant for all stakeholders. This uses rows to represent different perspectives or viewpoints on enterprise architecture (e.g., strategic planning vs. operations). Of course, Zachman did not specify where his guarantees can be redeemed and did not risk his own dollars while disseminating these ideas. A framework can be thought of as a template or scaffolding upon which a program or application can be built. a well-known chart, shown below. The tool has a common vocabulary and is meant to support all levels of architecture for enterprises both large and small. Zachman established seven guiding rules or principles for completing the two-dimensional matrix: The Zachman Framework is an agile and flexible framework that offers the stringent structure of a two-dimensional matrix. With the Zachman Frameworks 36-column matrix, you can catalogue all your organizations architecture, which can help your organization stay agile and flexible in the face of change by giving you detailed insights into your companys IT assets. (2001) You Can't "Cost-Justify" Architecture, Monument, CO: Zachman International. However, some architects still like the Zachman Framework because, unlike other EA frameworks, it is easy to use using it does not require studying extensive materials and does not imply doing anything in particular. It provides a structure for organizing information about its business processes and systems. 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 aimed at organizing and analyzing data, solving problems, planning for the future, managing enterprise architecture and creating analytical models. Scenarios or Use Cases view of the 4+1 framework. The Gartner Framework . The Zachman Framework uses the method of taxonomy to organize a massive variety of documents and materials into categories that suit them. The models creator Philippe Kruchten believed that by separating an architecture into distinct views, it will be displayed from a viewpoint of each stakeholder, be it a customer or a developer. Identifies strategic architecture needs, develops baseline and target architectures, and conducts gap analysis to develop architecture roadmaps and . 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. The people responsible for this seamless transition are enterprise architects. For example, if an architecture team is squabbling over whether events belong in SOA or not, the Zachman Framework shows that an EA perspective on SOA will unite the view of SOA construed as application architecture, which belongs in the function column, with the ideas of event-driven architecture, which falls largely in the time column. (T/F) True The Zachman framework divides systems into two dimensions: one is based on six reasons for communication; the other is based in stakeholder groups. 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 logic is recursive and generic, which means that it can be used to classify or analyze anything related to the enterprise architecture in question. Overall, the phenomenon of EA frameworks most certainly is a grand management fad that was shamefully swallowed by the EA community. 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. No sane human beings should ever consider the prescriptions of DoDAF seriously as an actionable guidance for their EA practice, as DoD did. 321-359. For example, Zachman Framework is better for businesses that need to model their entire enterprise, while TOGAF is better for businesses that need a more general overview of their architecture. Most EA frameworks are less dynamic than modern business toolkits such as Business Model Canvas. To fill in the matrixs columns and rows, you will need to input from stakeholders and will likely include redundancies and duplicate information. Executive Perspective a planner seeking information about a systems size and costs A framework is a structural representation of a model that enables you to determine what can be produced and when. Commercial Aerospace Corporation Accenture Boeing BMC Software Dell East bank technologies IBM Deloitte Gartner Group Oracle Samsung Government 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. Avoid altering the names of your rows or columns. In 2002, Intervista institute in Canada developed a new version with the development help of Mr. John. Over 100,000 professionals worldwide are certified with BCS. Therefore, instead of establishing a successful EA program in DoD, DoDAF consumed nearly $400 million and generated only the heaps of arcane documents unsuitable for decision-making purposes, in a way similar to FEAF16.

Logical represents what a system should functionally provide, system components and their relationships It is a proactive business tool, which can be used to model an organization's existing functions, elements and processes - and help manage business change. This effect amplifies the idea that there is more to it than just a matrix and adds further depth to an already intriguing concept. Process shows a systems performance, scalability, workflow rules Shortly after you start your inquiry about software architecture, or enterprise architecture as it is often called, you will come across the Zachman Framework.. But if you want to learn more about the framework or how to use it, the Zachman International offers official Zachman Framework training and certification through Zachman International. an organizations functions and processes Zachman Framework is one of the most famous enterprise architecture frameworks today. 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 7Stecher, P. (1993) Building Business and Application Systems with the Retail Application Architecture,IBM Systems Journal, Vol. Here we listed some of the familiar companies. 11-34. The first deals with interrogatives (who, when, why, what, and how - columns). If you are able to answer the Who, What, Where, How, and Why, then you will be able to derive the answers to any other questions about the subject or object. Reach decision makers at Liberty Office Professional Services, LLC, The FEAC Institute. * The Zachman framework explains all the angles that an organisation should consist of. Answer (1 of 5): I presume the question is about "better for career/job search", because certifications have little to do with your actual ability to deliver Enterprise Architecture. The framework draws on Zachman's experience of how change is managed in complex products. The most impressive enhancement of this version is the utilization of gradient color banding across the Rows and down the Columns. However, as with any widely recognized methodology, it has earned some criticism because of its theory-focused approach that few can turn into practice. These concerns dont necessarily mean that three decades of practice has led to EA frameworks becoming obsolete. However, SOA is more than simply an architectural approach for dealing with the functional aspects of systems. Zachman proposed the Zachman Framework for Enterprise Architecture (ZFEA), a descriptive, holistic representation of an enterprise for the purposes of providing insights and understanding. Prior to his research career, he held various software development and architecture positions in the industry. John Zachman was an IT pioneer who understood the problems facing IT-driven businesses. 80% of Global 50 companies and 60% of Fortune 500 companies use the TOGAF framework.
