For this reason, it is arguably impossible to develop more detailed one-size-fits-all prescriptive models for the processes of an EA practice. A simplified schematic view of enterprise architecture practice on a page is shown in figure 1. Various frameworks, modeling languages, tools and techniques have been developed, published, used and tested in practice. Why? Smith (ed.) Spewak, S.H., and Hill, S.C. (1992) Enterprise Architecture Planning: Developing a Blueprint for Data, Applications and Technology, New York, NY: Wiley. These three processes together provide a high-level picture explaining how an EA practice generally works. What other documents and techniques are relevant to these processes? What processes constitute an EA practice and who participates in them? It is now perfectly clear that all these EA methodologies and frameworks actually represented only passing fashions of no real substance: Enterprise architecture frameworks: the fad of the century2. In order to shed some light on genuine EA best practices that work in organisations and provide a handy reference model of enterprise architecture, previously I developed Enterprise architecture on a page as a convenient one-page view of popular EA artifacts that proved useful with their essential properties, e.g. Figure 1: Enterprise Architecture Practice on a Page (BCS). While there are numerous guides out there on how best to go about getting business buy-in or deliver effective enterprise transformation, they are oftentimes underwhelming. Emphasize strategic planning. Sometimes, an organization fails to effectively deliver enterprise architecture. It can be used as an intuitive visual model of an EA practice for teaching EA courses to students in universities. Initially, early architecture-based information systems planning approaches of the 1970s - 1980s, like BSP, Method/1 and Information Engineering, provided detailed guidelines for producing comprehensive architectures connecting business and IT. Analysing the escalation in the number of connected homes and increase in the market, Amir Kotler, CEO of Veego Software, makes five predictions for 2021. What EA artifacts are developed and used during these processes? Jyoti Choudrie FBCS, Professor of Information Systems at the University of Hertfordshire, talks to Johanna Hamilton AMBCS about COVID-19, sanity checking with seniors, robotics and how AI is shaping our world. Now, after all the waves of hype around architecture have gone and the dust has settled, what veritable knowledge on an EA practice is left to us? How keyloggers work and how to defeat them. It offers an evidence-based reference model of an EA practice to organisations starting their EA journeys, It provides a convenient framework for thinking about an EA practice to architects and architecture managers, It explains the general ideas and mechanisms of an EA practice to newbie architects. What questions are discussed as part of these processes? How do these processes relate to each other, to the external business environment and to the organisational IT landscape? Lankhorst, M. (2013) Enterprise Architecture at Work: Modelling, Communication and Analysis (3rd Edition), Berlin: Springer. Then, early EA frameworks of the 1990s-2000s, most notably the Zachman Framework and FEAF, offered their advice regarding the development of enterprise architecture for bridging the gap between business and IT. Successful EA practices represent flexible communication networks, where different planning decisions are made with the involvement of the right stakeholders at appropriate levels of the organisational hierarchy; but never mechanistic step-by-step analysis-synthesis processes similar to the ones prescribed by numerous faddish EA methodologies (e.g. Toggle Submenu for Deliver & teach qualifications, © 2020 BCS, The Chartered Institute for IT, International higher education qualifications (HEQ), Certification and scholarships for teachers, Professional certifications for your team, Training providers and adult education centres, Enterprise architecture frameworks: the fad of the century, The process view of enterprise architecture practice, Six types of enterprise architecture artifacts, The relationship between enterprise architecture artifacts, Enterprise architecture practice on a page (PDF), Enterprise architecture practice on a page. planning and implementing enterprise analysis to successfully execute on business strategies Moreover, these best practices are rather widely known and intuitively understood by the vast majority of experienced EA practitioners – though they are not codified or systematically documented in any sources and proliferate only verbally from architects to architects, predominantly through collaboration. Enterprise architecture involves the practice of analyzing, planning, designing and eventual implementing of analysis on an enterprise. Besides other things, Enterprise architecture practice on a page explicitly emphasises one critically important fact regarding an EA practice which is too often neglected: dialogue between various stakeholders is the core of an EA practice and constitutes the very essence of most EA-related activities. informational contents, presentation formats, typical use cases, lifecycles and purposes (see Enterprise architecture on a single page). There are so many of them, that it is hard to keep up. What is the goal and meaning of each of these processes? The Enterprise Architecture Standards are packaged as ‘Reference Content’, and is both agnostic and vendor neutral. Enterprise architecture (EA) is a discipline for proactively and holistically leading enterprise responses to disruptive forces by identifying and analyzing the execution of change toward desired business vision and outcomes. The Enterprise Architecture Standards are the result of years of international academic research and industry expert consensus on repeatable patterns that can be reused and replicated. Ironically, but the decades of motivating promises, excessive promotion and irresponsible marketing did not produce any systematic evidence-based descriptions of an EA practice and did not engender a sound understanding of how successful EA practices actually work. Information Engineering, Method/1 and BSP)1, 2. Each of these processes is based on specific types of EA artifacts from the CSVLOD model (see Six types of enterprise architecture artifacts and The relationship between enterprise architecture artifacts): strategic planning on considerations and visions, initiative delivery on outlines and designs, while technology optimisation on standards and landscapes (see Enterprise architecture on a page (PDF) for typical examples of respective EA artifacts). How to implement a clean, green data centre strategy. Traditionally the practice of using enterprise architecture (EA) for achieving business and IT alignment in organisations, or simply an EA practice, has been a subject of endless speculations and surrounded by countless faddish ideas, writes Svyatoslav Kotusev, Enterprise Architecture researcher. Then based on these questions, you can develop an approach and identify the models that you need. Enterprise architecture practice on a page has been discussed with a number of experienced enterprise architects who generally approved it, found it useful and provided their improvement suggestions – many of which I have incorporated into the resulting model (though, certainly not all of them fully agreed with all aspects of the model). By means of extending the process view of an EA practice and supplementing it with additional relevant information regarding the three processes (e.g. To develop a useful enterprise architecture (EA) it is important to first understand the questions you want to answer with your architecture. Kotusev, S. (2018) ‘TOGAF: Just the Next Fad That Turned into a New Religion’, In: K.L. For instance, none of the mainstream comprehensive texts on enterprise architecture (e.g. Currently, TOGAF is positioned as the leading EA framework or even as a global de facto industry standard for an EA practice1. Enterprise architecture helps businesses going through digital transformation, since EA focuses on bringing both legacy applications and processes together in an attempt to form a seamless environment.
