A Comparison of the Top Four Enterprise Architecture Frameworks (click to view larger image). The Zachman Framework is an enterprise architecture framework that provides a formalized view of an enterprise across two dimensions. 37-45. The fifth view Scenarios or Use Cases represents the high-level view of the whole system and illustrates an architectures consistency and validity. For example, the academic literature offers tens of papers devoted to analysing, comparing and formulating selection criteria for EA frameworks2. Enterprise Perspective an operational system itself, What? 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. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. 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). In 1987, this framework for information systems architecture was published in the IBM system Journal. Some people, after all, construe SOA narrowly as a form of application architecture, while other people think of SOA more broadly as EA. Zachman Framework: The Zachman Framework is a visual aid for organizing ideas about enterprise technology. 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. 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). 85. . 26, No. After that, people started referring to this framework and named it the Zachman framework., In 1993, John Zachman officially called his framework A framework for enterprise architecture., In 2001, After ten years of research and development and several refinements, this new version with six rows was become popular and recognized as the Zachman framework.. a well-known chart, shown below. While both frameworks have advantages, The answer depends on your business needs. Furthermore, the very genre of musing on frameworks is extremely popular among various EA writers. During The Open Group's 2015 San Diego event, John gave the morning's keynote address. Moreover, significant parts of the federal EA program have been complete and utter failures16 (page 6). For example, the business domain includes goals and objectives, strategy execution, value chain, and customers. The blueprint can be adjusted according to the new changes made, further improving the IT capabilities and structures. 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. 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.) Enterprise architecture is the roadmap the practice that encompasses the assessment, planning, and designing of your businesss use of technology to achieve its goals. The Zachman Framework for enterprise architecture was used as a guide for conducting interviews with security experts and auditors to identify existing frameworks, framework components and thoughts on the subject. the translation of business goals and strategies into specific means. alignment. A key element of this framework is that it avoids all redundancies in the final two-dimensional matrix. Lenovo Late Night I.T. Business Management Perspective an owner wanting to know how business processes interact Methodology refers to the systematic, logical approach to doing something. 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. Once the blueprint of the company has been developed, it can be refined and reused while making additional changes to the system. The Open Group Architecture Framework (TOGAF) is an industry-leading standard for developing, maintaining, and using enterprise architecture. 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. In addition, each stand-alone cell creates a space that better illustrates how much more occurs than in previous versions. The Department of Defense Architecture Framework (DoDAF) emerged in the mid-2000s as a common approach to architecture for the U.S. Department of Defense (DoD) and represents an evolution of the earlier C4ISR framework born in the 1990s17. 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. As with so many things in this domain, we have an opinion on the Zachman Framework and . No sane human beings should ever consider the prescriptions of DoDAF seriously as an actionable guidance for their EA practice, as DoD did. Thus the Zachman Framework shows that an EA perspective on SOA broadens the reach of SOA and doesnt require us to consider an overly narrow view of SOA, such as the SOA 2.0 nonsense currently proposed by some analysts and vendors. Originally developed by John Zachman at IBM in 1987, the Zachman Framework has been updated several times since. Zachman offers the most holistic approach to implement the EA framework into business models. Companies are looking for a model to understand the scope of their SOA initiatives so that they can build robust architectures that can withstand the ever-changing landscape of technologies, organizations, and methodologies. communication media. The Zachman Framework is not a methodology but rather a template describing how different abstract ideas are viewed from different perspectives. 0. 121-149. LOKASI Enterprise is a geospatial software that can be customized to support better corporate . Click on the cell you want to edit. The Zachman framework provides a means of classifying an organization's architecture. Figure 1. Of course, Zachman did not specify where his guarantees can be redeemed and did not risk his own dollars while disseminating these ideas. It is often used to develop applications faster and easier than starting from scratch. 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. The Zachman Framework helps organize SOA, but Service Orientation represents an organizing principle that can help guide organizations through the labyrinth of EA as well. Svyatoslav Kotusev is an independent researcher, educator and consultant. The Zachman Framework is a schema - the intersection between two historical classifications that have been in use for literally thousands of years. For example, if the research question changes partway through a study, the methodology should be able to change as well. [] The elapsed time required to produce the architecture makes it close to obsolete before completion. 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. (2010) Why Doesn't the Federal Enterprise Architecture Work?, McLean, VA: Technology Matters. Logical represents what a system should functionally provide, system components and their relationships With its every . The Zachman Framework focuses on content by defining the views that provide a holistic perspective of the organization. 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 Contact Us Still, its flexible enough to work for a project of any scope to clearly focus on each element and its purpose, and build contextual relationships between cells. Instead, its considered an ontology or schema to help organize enterprise architecture artifacts such as documents, specifications and models. It divides enterprise architecture into six domains. Enterprise architecture and the Zachman Framework bring together these points of view with others to create a complete picture of the architecture moving forward. It has only three columns. We also represent business processes as compositions of Services, and in turn expose processes as Services so as to enable agility and loose coupling. Or in other words, it is the skeletal model of building something.It describes how things are to be done.It explains what and when things need to be done.It is less flexible.It is more flexible. The difference between data architecture and enterprise architecture can be represented with the Zachman Framework.

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. Architect Perspective an architect determining how software functions represent the business model 3, pp. How the Zachman Framework maps to SOA 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 Gartner Framework . 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. (2010) Architecture Is Architecture Is Architecture, In: Kappelman, L. A. Zachmans key insight was to consider the problem of EA in two dimensions. The frameworks define the innate relationships between distinctive perspectives as well as rules. It provides a structure for organizing information about an organizations business, processes, data, applications, and technology. For instance, exactly the same well-known problems associated with all formal architecture methodologies had been reported earlier regarding TAFIM and ultimately led to its retirement (and thus to the emergence of TOGAF): TAFIM most certainly required a large investment of both time and money. This iterative approach to EA implementation is a best practice that ZapThink frequently discusses in its research and advisory into how companies can move to Service Orientation. The goal is to reduce these redundancies as much as possible, finishing with a concise document that delivers a clear picture into your organizations enterprise or IT architecture.

Where? These Zachman framework rules help architects and IT managers use the tool efficiently and effectively. The logical starting point for applying the Framework to SOA is the Application Architecture portion at the intersection of the Function column and Logical System Model row. However, besides analogous findings regarding other architecture methodologies13, 14, 15, the naivety of these beliefs was noticed previously even specifically in relation to the C4ISR framework, DoDAFs direct predecessor: The prevailing belief was that if one built the architecture, the owners and operators would come. The Zachman framework has several strengths: * The framework is known and is an accepted concept for enterprise architecture by the data community.

In the '80s, companies started to depend more on computers and technology in the workplace. 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). Furthermore, even Steven Spewak himself admitted that the vast majority of enterprises that undertake Enterprise Architecture Planning are not successful5 (page 19). (eds.) He is also the Executive Director of the Federated Enterprise Architecture Certification Institute ( The FEAC Institute) in Washington, D.C., as well as the Chairman of the . 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 . 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. The worlds largest enterprises use NETSCOUT to manage and protect their digital ecosystems. Applying the Zachman Framework to SOA, therefore, can help architects develop techniques for organizing IT and peoples relationship to it so that the organization can respond to change, and leverage change for competitive advantage. 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). 3Lapkin, A. and Weiss, D.

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. Each domain is further divided into sub-domains. For example, a methodology is used to gather and analyze data to find the answer for a research question. | It is difficult to estimate now how many people have been perplexed by his prescriptions and how much money has been spent in vain in organisations globally in the attempts to develop all the models made explicit at excruciating levels of detail, as Zachman recommended.
