TOGAF, FEAF and EAP) and their direct historical predecessors (e.g. Bernard, S.A. (2012) An Introduction to Enterprise Architecture (3rd Edition), Bloomington, IN: AuthorHouse. 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. Section 4 (Enterprise Architecture and City Planning) explains the key mechanisms of an EA practice and six essential types of EA artifacts based on the close analogy between enterprise architecture and city planning practices Free eBook: The Practice of Enterprise Architecture Experiences, techniques and best practices. Much of the growth and interest is being driven by the demands of digital business and the need for CIOs to start, restart or renew their EA programs. What other documents and techniques are relevant to these processes? There are so many of them, that it is hard to keep up. Likewise, every company has its own business case preparation approach, investment approval procedure, project delivery methodology and lifecycle, that all have to be properly integrated with the initiative delivery process through respective architectural reviews, assessments and approval gates. They misunderstand how to apply it, how to develop it, or how to sync it with the rest of the business. As we start to look to the year ahead, predictions about CIO priorities in 2021 are beginning to emerge, writes David Watkins, solutions director at VIRTUS data centres. Early EA frameworks are not completely forgotten yet, but their practical uselessness is seemingly already widely acknowledged within the EA community and the interest towards these frameworks is rapidly fading away. 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. Therefore, Enterprise architecture practice on a page offers only a generic conceptual framework for an EA practice relevant, arguably, to all organisations, but leaves out numerous details that may vary across organisations and cannot be specified in any generalisable form. 29-37. How do these processes fit into the organisational context? For this reason, it is arguably impossible to develop more detailed one-size-fits-all prescriptive models for the processes of an EA practice. How do these processes relate to each other, to the external business environment and to the organisational IT landscape? 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. 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 is the goal and meaning of each of these processes? Watkins argues that a green strategy should be discussed around every boardroom table. informational contents, presentation formats, typical use cases, lifecycles and purposes (see Enterprise architecture on a single page). Enterprise architecture involves the practice of analyzing, planning, designing and eventual implementing of analysis on an enterprise. Lankhorst, M. (2013) Enterprise Architecture at Work: Modelling, Communication and Analysis (3rd Edition), Berlin: Springer. Spewak, S.H., and Hill, S.C. (1992) Enterprise Architecture Planning: Developing a Blueprint for Data, Applications and Technology, New York, NY: Wiley. Currently, TOGAF is positioned as the leading EA framework or even as a global de facto industry standard for an EA practice1. Strategic planning converts a business strategy into a desired IT investment portfolio, initiative delivery turns each investment into a working IT solution, while technology optimisation rationalises the existing IT landscape. Since 2013, Gartner has observed a dramatic resurgence and growth of interest in enterprise architecture (EA). 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. the TOGAF manual and popular books of EA ‘thought leaders’ 3, 4, 5) provides a reasonably accurate description of established EA best practices familiar to most architects working in industry even from the purely factual perspective (e.g. How keyloggers work and how to defeat them. goals of each process, key questions discussed as part of each process, other non-EA-specific documents and techniques that might be relevant to each process), I produced a comprehensive diagram explaining various aspects of an EA practice and its constituting processes on a single page (importantly, this diagram focuses on internal EA practices carried out inside organisations, rather than on one-shot engagements performed by external EA consultants): Enterprise architecture practice on a page (PDF). The survey results also indicate that EA teams at digital leaders … In this article, I will introduce another helpful deliverable called Enterprise architecture practice on a page. As a result, at the present moment, for outsiders, an EA practice still remains largely an inexplicable ‘black magic’ full of weird buzzwords, inconsistent models and frameworks. Then based on these questions, you can develop an approach and identify the models that you need. Figure 1: Enterprise Architecture Practice on a Page (BCS). Information Engineering, Method/1 and BSP)1, 2. Nevertheless, during my own research of EA practices in organisations I realised that despite the evident chaos observed in the EA literature, a set of remarkably consistent best practices around enterprise architecture has emerged in industry. For example, specific actors, deliverables, communication patterns and decision-making responsibilities relevant to the strategic planning process will naturally differ rather significantly from organisation to organisation. 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. How to implement a clean, green data centre strategy. This simple, one-page view of an EA practice provides clear, evidence-based and concise answers to the following essential questions: Importantly, low-level details of each of the three processes in successful EA practices are always organisation-specific. 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 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). While Enterprise architecture on a page focuses solely on EA artifacts as visible, tangible and static elements of an EA practice, Enterprise architecture practice on a page focuses on EA-related processes as somewhat less visible, immaterial and dynamic elements of an EA practice. 12, No. 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? 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. planning and implementing enterprise analysis to successfully execute on business strategies However, early architecture-based planning methodologies all proved impractical long ago, disappeared without a trace and today almost no one remembers that they ever existed. Emphasize strategic planning.
