While some say enterprise architecture frameworks are unnecessary and don’t work, there is an argument in favor of enterprise architecture, whether it is through a formalized framework or a through a top-notch employee who sees these benefits. The traditional approach to enterprise architecture – the analysis, design, planning and implementation of IT capabilities for the successful execution of enterprise strategy – seems to be missing something … data. Enterprise Architecture In The Strategic Planning Lifecycle EA is often seen as bringing an ‘ivory tower’ perspective in the adoption of new ideas. EA helps organize and illuminate the relationships among the enterprise's strategic goals, investments, business solutions, and measurable performance indicators. Any optimization for EA needs to make sure that all stakeholders are on board and that they remain involved along the way—the business, the IT crowd on the ground, management, and the enterprise architects themselves. For this reason, an external repository is required as an exogenous justification of the steps and the effort required of each participant. Microsoft's Michael Platt, a director in the strategic projects group, offers a view of enterprise architecture as containing four points of view: the business perspective, the application perspective, the information perspective and the technology perspective. Enterprise Architect can store resource information along with the model. 2. , for instance, shows a neat way to close the ubiquitous, awkward breach between, Modeling Enterprise Architecture with TOGAF, Essential DW/BI Background and Definitions, Agile Data Warehousing for the Enterprise, A Semantic Approach to Security Policy Reasoning, Journal of Industrial Information Integration, Get Rid of Waste by Streamlining Architecture Processes, Values the sparse time of enterprise IT stakeholders by focusing on lean processes with as little management overhead as possible, Involve All Stakeholders by Interlocking Architecture Scrums, Makes sure that all stakeholders are involved by focusing on structured human interaction as a main channel of information flow, Practice Iterative Architecture Through EA Kanban, Welcomes change and favors iterative design over large-scale upfront planning and supports this approach with tools and methods, Pursues new traits of sharing and combining knowledge by building self-organizing, company-wide information repositories, Allows collaborative decision making by the relevant stakeholders on the ground, Fosters transformation (that eventually changes the IT landscape) by participation, The identification of systems, system items, and their interconnections, A description of resource flows exchanged between systems, The relationships among systems in a given architectural description, The functions performed by systems and the system data flows among system functions, Operational activity to systems function traceability matrix, A mapping of system functions back to operational activities, Operational activity to systems traceability matrix, A mapping of systems back to capabilities or operational activities, Provides details of system resource flow elements being exchanged between systems and the attributes of those exchanges, The measures (metrics) of Systems Model elements for the appropriate timeframe(s). In software development, as project architects, we worked for years with lean and agile methods. The purpose of the EPA Enterprise Architecture. Across the many frameworks that serve to achieve an enterprise architecture, the goal of the comprehensive approach is always to successfully execute strategy with efficiency, efficacy, security, durability, and agility. EA offers: An insight into the current utilization of IT in business operations, A vision for the future utilization of IT in business operations, and. Architecture and DevOps. Altogether, our improvement approach for EA adheres to the following three guidelines: Establish a lean set of processes and rules instead of overloading the stakeholders with bureaucratic processes and unsolicited artifacts. Enterprise architecture (EA) is a discipline with a much larger scope than data warehousing. TOGAF security considerations would start by determining the following: Who are the legitimate actors who interact with an enterprises product service and process? One area that enterprise architecture will undoubtedly need to grapple: the “app store mentality”. Physical and cloud servers, applications, and enterprise software all must communicate and share data seamlessly in order to provide the customer a successful and satisfactory user experience. A federal enterprise architecture framework is the U.S. reference enterprise architecture of a federal government. BMC was among the select companies that Forrester invited to participate in its Q4 2019 Forrester Wave Evaluation, Enterprise Service Management. After all, frameworks are static pieces of guidance for businesses and technologies are constantly shifting. The Open Group Architecture Framework (TOGAF) 3. Training. The people element brings complex behavioral attributes into the functioning of an enterprise in the same way as it turns a house into a home. Enterprise-grade conversational bot. We use cookies to help provide and enhance our service and tailor content and ads. Enterprise architecture is a collective practice that aims to find compromise between divergent views and that requires each party to cooperate for the common good. Both too much order and too much chaos are counterproductive. It is based on the dimensions of EA complexity introduced in the previous sections. All architectural levels include information systems to some degree, but information system development and implementation is ordinarily addressed at the solution architecture level. Understanding scope and governance is important, because clearly, if parts of the organization can do what they like, then there is little value in an Enterprise Architecture. But deeper historic inquiries indicate that enterprise architecture frameworks actually got their start two decades earlier, when IBM produced their business systems planning (BSP), an effort that Zachman helped found. In Chapter 4, “EA Frameworks,” we describe the most well-known frameworks for structuring EA tasks and organizing an EA practice. Ivan Launders, Simon Polovina, in Strategic Intelligence Management, 2013. Enterprise Architecture Approach -TOGAF 9- Prashant Patade (Enterprise Architect)Strategic Projects and Core Technology Group - IT Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Today’s computer and technology systems are complex – especially when they are responsible for so much of the productive activities within most organizations. An illustration of enterprise architecture and its purpose. Enterprises often employ an enterprise architect whose responsibility includes the overall alignment of IT and business needs to achieve business strategy. Enterprise Analysis is a knowledge area which describes the Business analysis activities that take place for an enterprise to identify business opportunities, build a Business Architecture, determine the optimum project investment path for that enterprise and finally, implement new business and technical solutions. Figure 2-3. Enterprise architecture is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Guidance surrounding this implementation are often known as enterprise architecture frameworks (EAFs), which we are exploring from a high level in this article. Unfortunately, the enterprise architectural plans can be challenging to support should the EA group be actively updating its artifacts while the warehouse is undergoing design and construction. We do not believe we have the panacea for all grievances about EA. U.S. Department of Defense Architecture Framework (DoDAF) 2. Apart from pure EA, the role of an enterprise architect extends into the realms of other IT management practices as well, especially in strategic enterprise planning, IT investment management, IT project management, and IT infrastructure management. From core to cloud to edge, BMC delivers the software and services that enable nearly 10,000 global customers, including 84% of the Forbes Global 100, to thrive in their ongoing evolution to an Autonomous Digital Enterprise. If you have existing architectures for projects or lines of business, and you want to create an enterprise architecture, the easiest approach is to populate your EA from the bottom up. Enterprise Architecture Governance Procedures. This idea can be summed up in two main challenges: How can we structure EA activities on a day-to-day basis in order to master a demand-driven workflow at all levels of operation and achieve a holistic result? EAM translates the enterprise vision into venture and takes the enterprise through the journey from its current state to the target state. How to determine the assets at risk if something goes wrong, that is, what is being protected, How to determine the costs both in terms of qualitative and quantities of asset loss in case of failure. The answer is given by a concept called the Edge of Chaos, originally introduced by Kauffman (1995) and Brown and Eisenhardt (1998). The first three are based on lean principles and agile practices from erstwhile software development, whereas the remaining three are drawn from Web 2.0 and Enterprise 2.0 concepts. Warsaw Office. Hence, the term architecture does not literally apply to the enterprise in the same way as it has been traditionally applied to technical systems. But there always was wide room for improvement, and tendencies to the one or other caricature described in the previous sections were always perceptible. Some proponents of EAFs even see that enterprise architecture can bridge the gap between the IT and business silos that often exists within companies. Agile transformation program. A researcher of 20th– and 21st-century technology, Svyatoslav Kotusev says that we can look at the history of EAFs in three smaller eras: Despite the differences in approaches that these eras indicate, all frameworks are generally based on the original BSP methodology, often advocating similar steps or phases for planning and implementing enterprise IT. Stephen D. Gantz, Daniel R. Philpott, in FISMA and the Risk Management Framework, 2013. Figure 2-2. After wrapping up the main ideas, we sketch the next steps for an enterprise architect who wants to implement some of these ideas in his or her daily work. Read more about MEGA. Adopt evolutionary problem solving instead of blueprinting the whole future rigidly on a drawing board. The emerging technologies, software/hardware products, and skills that are expected to be available in a given set of timeframes and that will affect future system development, Identifies constraints imposed on systems functionality due to some aspect of system design or implementation. Those developed and released as open source. There is a lot to be done. With Chapter 9, “The Next Steps: Taking Collaborative EA Forward,” we conclude the book. This model identifies the process steps necessary to perform EAP and create an Architecture Migration plan. It also marks the social software functionality the examples rely on, with a solid bullet highlighting the most crucial ones. The EA approach advocates for an enterprise mindset necessary to drive enterprise-level integration of business and technology. As part of an increased focus on security The Open Group has released new guidelines developed in collaboration with the SABSA Institute to enable enterprise and enterprise architects to integrate security and risk management approaches into enterprise-level architectures with the aim of aligning IT security decisions with business goals across the enterprise, therefore adopting a business-driven approach to IT security decisions. Our approach to stabilising, standardising and optimising EA in an organisation is based on the following principles:Clearly defined EA products and services to be delivered to the EA customers.A meta-model defined and implemented on architectural principles enabling effective repository management and quality modelling.EA governance implemented by a central EA office. We will see how lean and agile thinking can be successfully incorporated into typical EA activities and processes, and how this will increase EA effectiveness, flexibility, and pragmatism. The role of an enterprise architect Enterprise architects are typically not accountable for the enterprise's IT strategy. Figure 8-26. Before delving into the details of our improvement building blocks, Part I of the book first explores in detail what EA is. Organizing the elements that … There is one more fundamental distinction of EA that should be noted here. Project Approach . Ensure everyone speaks the same language 2. Reference models can therefore be used to capture patterns of security activity that are reusable assets in enterprise architecture. This platform can be a weapon against the divergence of high-level vision and ground-level facts. The implementation of the third guideline, fostering participation, is provided by three further building blocks, as shown in Table 1-3. Stefan Bente, ... Shailendra Langade, in Collaborative Enterprise Architecture, 2012. By Stuart Macgregor, CEO, Real IRM Solutions and The Open Group South Africa Avoiding the perils on the way to successful Enterprise Architecture Enterprise architecture (EA) is more relevant today than ever before – considering the accelerating pace of technology adoption, many new and disruptive market forces, hyper-competitive environments, and rapidly changing business models. Enterprise architecture strives to mature the organization's ability to complete projects on schedule and budget, by optimizing performance. With respect to business processes, businesses themselves are dynamic and must change to adapt with the latest… OMB developed a set of reference models, practice guidance, and an enterprise architecture assessment framework under its Federal Enterprise Architecture program. An enterprise is a business, company, firm, or group of any size that provides consumers with goods and/or services. PURPOSE. The paper will then lay out an approach for achieving timely and meaningful deployment of such an initiative. It reflects the current and future use of IT in the enterprise and provides a roadmap to reach a future state. Therefore, it takes away some negative side effects and risks that people experience on a permanent construction site. See an error or have a suggestion? Only through such integration can EA provide a stable foundation for sound IT management practices, end-to-end governance of IT investments, and alignment of IT implementation with the enterprise's vision and strategic goals. From the EA perspective, information systems are the focus of solution architectures developed to describe organizational IT assets such as applications or service components that support individual agency business functions. We encourage you to use this book as a toolbox. This is also true for mobile application development. With lean and agile methods, we could approach complex problems in an iterative fashion. “Chaos is created by people trying to solve immediate business problems, [and] you need to harness that energy even if it creates systems chaos,” writes Eckerson (2011). Malcolm Chisholm, in Pragmatic Enterprise Architecture, 2014. The first phase of the Systems Development Life Cycle (SDLC) is called . Common architecture enables agile teams to focus on value creation. These may be the best candidates for enterprise architecture. These two interrelated things have a significant impact on the effectiveness of what can be achieved. The core tool is an architecture social software platform that is well integrated into other tools such as a configuration management database (CMDB) or dedicated EA tools. The benefit of EA 2.0 in guiding transformation is summed up in the Dashboard assessment in Figure 8-26. A modern approach to enterprise mobile application development. across the enterprise. 52. March and Simon (1958) define enterprises as complex systems comprising individuals or groups that coordinate actions in pursuit of common goals. It therefore helps avoid the notorious friction between what is written in the high-level specifications and code-level reality and draws the Perspective gauge away from Cloud Cuckoo Land. Please let us know by emailing blogs@bmc.com. Simply stated, enterprise architecture framework (EAF) refers to any framework, process, or methodology which informs how to create and use an enterprise architecture.So, what is enterprise architecture?At a high level, enterprise architecture offers a comprehensive approach and holistic view of IT throughout an enterprise. 2,000+ Enterprise Customer s. 340,000+ Users. ©Copyright 2005-2020 BMC Software, Inc. The Open Group Architecture Framework (TOGAF), for example, recognizes the importance of security design early on in a project life cycle and has provided a significant move toward including security in the design of enterprise architecture (SABSA, 2011). In contrast to the traditional architecture practices, which primarily look at pure technical systems such as a bridge, a car, or a plane, EA deals with a socio-technical system. Practicing lean and agile methods means welcoming change, planning and executing incrementally, and focusing on structured human interaction instead of channeled reporting lines. All four of the layers comprising the Federal Enterprise Architecture Framework—business, data, applications, and technology—relate to the design, development, and operation of federal information systems. Enterprise Architecture, Building Blocks, Project Scope, Planning, TOGAF, Inspired EA Frameworks 1 Introduction to the Problem The author and colleagues are engaged in a consulting capacity with a rapidly expanding Telco in South Africa. These building blocks are the cornerstones of Collaborative Enterprise Architecture. What Is Enterprise Architecture? First we describe the core concept of enriching the traditional EA methodology with collaborative Enterprise 2.0 mechanisms. We wish you as much pleasure reading it as we had writing it. The planned states can be project architectures or transition architectures and ultimately target architectures. Companies will move away from buying and managing physical servers on site. This difference is like the difference between a house and a home. Yet without the understanding of the disciplines involved, there is likely to be a high failure rate, and anecdotes of this are already circulating. Having examined the state of the art in EA, we come to our improvement proposals in Part II of the book, which consists of Chapters 6 through 8Chapter 6Chapter 7Chapter 8: Chapter 6, “Foundations of Collaborative EA,” comes back to the three guidelines for collaborative EA we stated earlier: the application of lean, agile, and Enterprise 2.0 concepts to EA. Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. These types of questions bring focus to the security design identifying and assessing the vulnerability and control concepts for an asset and therefore the value at risk. Enterprise architecture management (EAM) is a structured approach that an enterprise uses for creating, managing, and using enterprise architecture to align business and IT. This idea further leads us to introduce the EA Dashboard that combines the EA caricatures from the preceding section with the Edge of Chaos concept. The EA approach advocates for an enterprise mindset necessary to drive enterprise-level … Organization design . The organization has a newly established enterprise architecture (EA) function. Although the complexity of a data warehouse tempts one to plan solely within the boundaries of his or her current project, the needs of the enterprise will soon impinge on a project so narrowly defined. It does not change the pace of change, but it helps that the organization actually can manage this pace. While these frameworks are often rigid and structured, which might not align with constant change inherent in 21st century business and technology, using the frameworks as guidelines instead of as gospel may prove beneficial – after all, companies still need a structured approach to infrastructure. Enterprise architecture (EA), then, is loosely defined as the architecture of a system where the system is the whole enterprise. Resources. To design an organization means to set up a stage where the drama of life will take place. The EA Dashboard for Building Block 6, Participation in transformation. Definition: Architecture development can be thought of as both a process and a discipline that aids the development of mission-effective systems. Implementing transitional architecture. We have condensed them as six building blocks of collaborative EA and present them in Chapters 7 and 8. In the Pre-EA era, planning for implementation was prohibitively expensive and time consuming. We establish a theoretical foundation to reason out these questions. Make Smarter Decisions Faster with a Pragmatic Approach. Already we see enterprises rushing into this area and willing to spend large sums on standing up technology. Among other provisions, the Clinger-Cohen Act requires federal agencies to develop and maintain an “integrated information technology architecture” [31], a requirement satisfied through the establishment of enterprise architecture programs at virtually all federal agencies. In the digital fast-paced era, the company that doesn’t want to lose big to its more innovative competitors has to embrace innovation. The transformation of business requirements into information technology requirements and implementation has a checkered past, often resulting in business requirements being driven by information technology rather than information technology requirements being driven by the business. Approach. An enterprise architecture roadmap is a strategic blueprint that communicates how a company’s IT plans will help the organization achieve its business objectives. Operating model and alignment. With the fundamentals of Collaborative EA laid in Chapter 6, we will turn back to concrete reasoning about corrective measures and practical steps to be taken. Waszyngtona 26 lok. Each building block provides concepts that base EA on a more diverse, widespread judgment instead of restricting it to the wisdom of a few experts alone. We will measure the potency of our proposed EA improvements against this Dashboard. What makes EA complex? Why are agents likely to be a threat? This does have an effect on the approach of this book, too. Documenting systems at this level of detail facilitates the identification of functional and technical characteristics of systems and their interconnections that may have implications for security requirements and the controls implemented to meet those requirements. These are collectively referred to as the architecture blueprint. The planned steps for migrating a suite of systems to a more efficient suite, or toward evolving a current system to a future implementation. Approach. Enterprise Architecture (EA) is not just an approach to fix a single problem — it helps develop an entire ecosystem to run the business smoothly. But why are both an IT PMO and EA necessary? With a structured enterprise-content management (ECM) strategy, ... • Standard enterprise-wide information architecture • Data conversion needs • Need for application rationalization • Greater/better use • Need to support ECM content governance • Content-intensive processes developed in silos • Lack of or non-optimized automated/ manual content/process hand-offs • Pro Instead of the inflexible waterfall model, we could use a lightweight, efficient, and human-centric approach. In many cases, IT governance frameworks like ITIL or COBIT can help to inform the overall enterprise framework strategy. By aligning business needs across all silos, companies can visualize actual business motives and drivers. Some of the most popular approaches used in government departments and agencies are: 1. When performed at its best, an enterprise architecture translates the vague and intangible business strategy to practical, concrete plans and actions. Enterprise architecture remains a difficult art that requires the support of methods like TOGAF from The Open Group. But, in the context of this new, integrated approach to strategic planning, the EA function becomes more integrated within the organization and more focused on clearly defined objectives. Table 8-3 lists the EA activities with the closest relationship to the application examples of ACM and CMM. In the Enterprise Chess approach to enterprise architecture (see the book or the presentation), the natural tension between Solutions (or ‘Products’ in Agile) and Enterprise Architecture is managed by creating ‘consent’-based collaboration and checks & balances between the solutions perspective and the enterprise perspective. Enterprise architecture establishment need to be tied… When plans were achieved, they were heavy and dense, very abstract, and difficult to understand, which means they were difficult to implement across the entire organization. But experts question how this download-and-go attitude will affect a holistic enterprise architecture where things are heavy and significantly less speedy. EA documents the structural and behavioural building blocks that How can we elicit the participation of all, in particular the ground-level stakeholders, to balance the helicopter view and the ground-level perspective? Basic Steps to Build an Enterprise Architecture Practice from Scratch Published on April 30, 2016 April 30, 2016 • 107 Likes • 22 Comments Enterprise architecture, when performed in a disciplined agile manner, is an important enabler of agile software delivery. It provides a common approach for the integration of strategic, business and technology management as part of organization design and performance improvement. These roadmaps can be developed for initiatives such as: Communicating a change management plan — for example, to move the company to new tools or technology. Avoid lock-in to proprietary solutio… The Enterprise Architecture functions as a significant diagnostic tool for identifying the source of problems that arise and for planning improvements. 37, 03-910 … As a general rule, based on our analysis of the EA failures in the previous section, it makes sense to seek a middle ground between the extremes on each gauge. The countermeasure here is to introduce more participation of groups outside the “inner circle” into decision-making processes. Table 4.1. At their best, successfully adopted EAFs can bridge the gap between the IT and business worlds – in doing so, the way an organization views and achieves IT can be vastly improved. Whereas a framework has the potential to muddy the waters, a skilled enterprise architect – the person responsible for this holistic vision come to life – may be exactly what a company needs. Some under organizational architecture understand building blocks, which are mandatory for the growth of the organization. The architecture should also incorporate 21st century practices of business process management and data analytics. So the corollary is that if one has been assigned the task of establishing an Enterprise Architecture or enterprise data model and he or she can see that governance does not exist for the scope intended. This is true for several reasons: 1. Establish Clear Vision and Scope According to Rico (2006), it is important to know what is to be achieved by the creation of enterprise architect. These roadmaps can be developed for initiatives such as: Communicating a change management plan — for example, to move the company to new tools or technology. As we will see, the real issue is to balance chaos and order properly. The enterprise architects of a company maintain a list of prioritized, aligned initiatives and road maps defining the present and future of the company: [EA presents] business and IT leaders with signature-ready recommendations for adjusting policies and projects to achieve target business outcomes … [and] steer[s] decision making toward the evolution of the [desired] future state architecture. Enterprise architecture (EA) is an information resources management discipline that links strategic goals, objectives, and performance measures to programs and business processes implemented to realize the organization’s strategy and to the information technology and other resources allocated in support of that strategy. This fact carries great consequences for the way EA should be looked at and dealt with. Often compared with town-planning or urban design, Enterprise Architecture (EA) is a holistic approach to managing the complexity of IT from a business perspective. The practical implementation of these concepts has been condensed into three concrete building blocks, as outlined in Table 1-2.
