[2] The systematic use of EA artifacts for collective decision-making distinguishes a disciplined approach to information systems planning from an ad hoc and ill-organized one. some sections of an EA artifact are intended primarily for business stakeholders, while other sections of the same EA artifact are intended primarily for IT stakeholders, Implicit duality is when same parts of EA artifacts are interpreted differently by different actors, e.g. Enterprise architecture is widely accepted as an essential mechanism … 1 Introduction. Winter, Robert & Fischer, Ronny: Essential Layers, Artifacts, and Dependencies of Enterprise Architecture. One of the most important properties of EA artifacts is the duality of their informational contents. BCMs and roadmaps are definitely the most common EA artifacts related to the, Solution overviews (can be called conceptual architectures, solution outlines, conceptual designs, preliminary solution architectures, solution briefs, etc.) Sharing knowledge sesi pertama tanggal 15 Maret diisi dengan pembahasan paper yang berjudul “Essential Layers, Artifacts, and Depedencies of Enterprise Architecture”, yang ditulis oleh Robert Winter dan Ronny Fischer, serta dipublikasikan pada 10th IEEE International Enterprise Distributed Object Computing Conference Workshop (EDOCW'06). Additionally, some EA artifacts can describe a combination of all these states in different proportions or can even be essentially stateless, i.e. From the perspective of their properties all EA artifacts can differ in their informational contents, general meanings and lifecycles in the context of an EA practice. An enterprise architecture framework (EA framework) is the collection of processes, templates and tools that are used to create an enterprise architecture ().An enterprise architecture is a conceptual blueprint, and the purpose of a framework is to help architects, designers and engineers understand how an organization's systems and assets are logically structured and … Learn about the ADM phases step-by-step. Enterprise architecture is widely accepted as an essential mechanism for ensuring agility and consistency, compliance and efficiency. reflections of the actual current situation in an organization as it is. Enterprise architecture (EA) is defined as the organizational logic for business processes and IT infrastructure by MIT. EA literature describes many detailed EA methodologies, artifacts and frameworks to organize them. You can access the ADM process navigator anytime throughout the ADM cycle by selecting ADM > TOGAF®from the application toolbar. Previously, I reported that all EA artifacts used in established EA practices can be classified into one of the six general types: Considerations, Standards, Visions, Landscapes, Outlines and Designs (CSVLOD), accurately defining their practical roles (see Six types of enterprise architecture artifacts, Eight essential enterprise architecture artifacts and The relationship between enterprise architecture artifacts). They are based only on informed opinions of their contributors regarding the desirable future course of action and shaped primarily by the key interests of their stakeholders. The green circle on the left indicates the start of the ADM cycle, while the red circle on the right indicates the end. do not focus on specific points in time. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): After a period where implementation speed was more important than integration, consistency and reduction of complexity, architectural considerations have become a key issueof information management in recent years again. Essentially, facts EA artifacts play the supporting role in an EA practice by providing the information base required for developing decisions EA artifacts. Technology reference models (TRMs) (can be called technology standards or split into infrastructure, applications and other more specific reference models) provide standardised sets of available technologies to be used in all IT projects structured according to their domains, often with their lifecycle phases color-coded. accumulated in organizations gradually over time. Their general purpose is to help make optimal planning decisions approved by all relevant stakeholders. general types of E A artifacts found in all more or less mature EA … Since any ideas regarding the desired future always imply collective decisions, all EA artifacts describing the future state, as well as all stateless EA artifacts also having specific implications for the future, can be automatically considered as decisions EA artifacts from the perspective of their general meaning in an EA practice, Facts EA artifacts represent documented objective facts, i.e. Since a mere documentation of the current situation does not imply any real decisions, all EA artifacts describing only the current state can be automatically considered as facts EA artifacts from the perspective of their general meaning in an EA practice, Explicit duality is when different parts of EA artifacts are relevant to different groups of actors, e.g. Solution overviews are the most common EA artifacts related to the, Solution designs (can be called high-level designs, solution definitions, detailed designs, full solution architectures, project-start architectures, etc.) Six General Types of EA Artifacts. Permanent EA artifacts are created once and then updated when necessary according to the ongoing changes in an organization and its business environment. Mixed EA artifacts can contain the elements of all these representation formats in different proportions, EA artifacts can provide different levels of detail. EA artifacts are main instruments of an EA practice enabling effective decision-making and IT planning in organizations. He is an author of the book The Practice of Enterprise Architecture: A Modern Approach to Business and IT Alignment and many articles on enterprise architecture that appeared in various academic journals and … specific business activities, IT systems, databases, etc. Solution designs of ~25-50 pages long are typically developed for all approved IT projects collaboratively by architects, project teams and business representatives to reflect both business and architectural requirements. the same diagram in an EA artifact is relevant to both business and IT stakeholders, but has significantly different implications for each of these parties, This page was last edited on 2 November 2020, at 08:48.

EA artifacts provide descriptions of an organization from different perspectives important for the various actors involved in strategic decision-making and implementation of IT systems. Importantly, these EA artifacts represent eight consistent groups of EA artifacts with very similar meaning found in different organisations regardless of their organisation-specific … Purely textual EA artifacts contain only plain text. It provides support across a number of areas and solutions, for example, digital transformation, customer journeys and value streams, process au… The components can be shared (cross cuts) or the component ca… They can be considered as key elements and cornerstones of an EA practice. It describes a method for developing and managing the lifecycle of an enterprise architecture, and forms the core of TOGAF. [4] EA artifacts can be very diverse in their basic properties and attributes. The "architecture" o… The Essential Enterprise Architecture tool helps you to understand how the people, functions, processes, IT applications, data, infrastructure, suppliers and customers interact across the business. Note: 1. First of all we need a definition of what an EA artifacts is. An EA component is in the Enterprise Architecture components are those elements that are owned by Lines of Business. Descriptions contained in EA artifacts can range in their granularity from very high-level abstractions (e.g. Enterprise architecture artifacts (or EA artifacts) are separate documents constituting enterprise architecture. The concepts discussed in this section have been adapted from more formal definitions contained in ISO/IEC 42010:2007 and illustrated in Figure 35-1. Architectures of all IT projects are reviewed by architects to ensure their alignment to TRMs and thereby achieve overall technological homogeneity and consistency of the IT landscape. Duality of EA artifacts can be explicit or implicit: In other words, duality of EA artifacts implies either providing different information to different actors, or providing same information having different meanings for different actors. That article also highlighted the need of having a reference architecture in place. The key element of the CSVLOD model is the taxonomy for EA artifacts providing a classification scheme for grouping diverse EA artifacts into six consistent groups according to their essential roles and properties. Essentially, an EA practice revolves around using specific sets of EA artifacts for improving communication between different actors.[3]. Enterprise architecture is a […] My thoughts on Service Management, Digital Core and how transforming IT Operating Models can deliver Operational Excellence. Artifact. Eight activity areas of enterprise architecture practice Their duality allows using EA artifacts as a means of communication and partnership between different groups of actors involved in strategic decision-making and implementation of IT systems. Decisions EA artifacts are inherently subjective, speculative and people-specific in nature. Agile architecture means how enterprise / system / software architects apply architectural practice in agile software development.A number of commentators have identified a tension between traditional software architecture and agile methods along the axis of adaptation (leaving architectural decisions until the last possible moment) versus anticipation (planning in … Citation. 2006. These six general types of EA artifacts … Facts EA artifacts are based only on acknowledged “hard” data and largely independent of specific people involved in their development. A "system" is a collection of components organized to accomplish a specific function or set of functions. In the last article, a few key terms like reference architecture, artifacts and types of artifacts were explained. - EDOC Workshop on Trends in Enterprise Architecture Research (TEAR 2006), 10th IEEE International Enterprise Distributed Object Computing Conference Workshops … Built, and continually evolving, based on our experience as enterprise architecture consultants to many of the world's top organisations, Essential has been built for architects, by practising architects, with a meta model and views geared towards delivering stakeholder value and answering the key enterprise architecture questions. Since objective facts are normally not discussable and do not require any real decision-making, these EA artifacts may be developed or updated solely by specific actors, but represented in formats convenient for their future users. Architectural artifacts are created in order to describe a system, solution, or state of the enterprise. All states typically described in EA artifacts can be roughly separated into the current state (now), short-term future state (<1 year), mid-term future state (2-3 years) and long-term future state (3-5 years). Enterprise architecture (EA) is a description of an enterprise from an integrated business and IT perspective intended to improve business and IT alignment. TRMs are typically developed by architects and subject-matter experts in specific technologies and then updated in a periodic manner, often yearly.

Enterprise architecture is a description of an enterprise from an integrated business and IT perspective intended to bridge the communication gap between business and IT stakeholders and improve business and IT alignment. describe an organization at different points in time. principles, technology reference models, … View Six Types of Enterprise Architecture Artifacts.pdf from ICT 301 at Murdoch University. Different EA artifacts are used by different actors at different moments for different purposes and fulfill different roles in organizations. Even though both TRMs and guidelines describe some implementation-level technical rules relevant to IT projects, they are complementary to each other because TRMs provide lists of technologies to be used, while guidelines define more narrow prescriptions regarding their usage. specific IT initiatives or projects, tend to be temporary EA artifacts, Decisions EA artifacts represent made planning decisions, i.e. business or IT capabilities, overarching rules, executive-level considerations, etc.) The notation used is from the Unified Modeling Language (UML) specification. describe specific IT projects in a brief business-oriented manner, usually including their high-level architectures, expected business value, estimated costs, risks and timelines. to pretty low-level details (e.g. Svyatoslav Kotusev is an independent researcher, educator and consultant. Six Types of Enterprise Architecture Artifacts Svyatoslav … An artifact is any physical piece of information used or produced by a system. Solution overviews of ~15-30 pages long are typically developed for all proposed IT projects at their early stages collaboratively by their business sponsors and architects. ), EA artifacts can cover different organizational scopes. After decisions EA artifacts are created and approved, all their stakeholders should be ready to act according to the corresponding planning decisions reflected in these EA artifacts. [2] EA artifacts provide descriptions of an organization from different perspectives important for the various actors involved in strategic decision-making and implementation of IT systems. Considerations, Standards, Visions, Landscapes, Outlines and De signs are the six. These eight essential EA artifacts are principles, technology reference models, guidelines, business capability models, roadmaps, landscape diagrams, solution overviews and solution designs. 5.1.1 The ADM, Enterprise Continuum, and Architecture Repository It integrates elements of TOGAF described in this document as well as other available architectural assets, to meet the business and IT needs of an organization. After facts EA artifacts are created, they can be used by any actors as reference materials for planning purposes. Basically, it is the system you use to organize the resources at your disposal. Enterprise architecture (EA) is the practice of conducting enterprise analysis, design, planning, and implementation using a holistic approach for the successful development and execution of strategy. It provides a one-page aggregated view of core processes constituting an EA practice with their interrelationships and most essential properties, including their main goals and motives, necessary participants, underlying EA artifacts and documents, key activities and … Please note that the EA artifact documents the EA component. Essential enables you to spot opportunities to improve and to assess the impacts of planned changes to the operating model. You should see the screen below. Specifically, EA artifacts can be represented in textual, graphical and sometimes tabular formats, or as a mix of these formats. Scott A. Bernard defines “an EA artifact as a documentation product, such as a text document, diagram, spreadsheet, briefing slides, or video clip” (Bernard 2004, p. 111). Typically EA artifacts covering wider scopes are less detailed, while EA artifacts covering narrower scopes are more detailed, EA artifacts can focus on different temporal states of an organization, i.e. Essential Layers, Artifacts, and Dependencies of Enterprise Architecture @article{Winter2006EssentialLA, title={Essential Layers, Artifacts, and Dependencies of Enterprise Architecture}, author={R. Winter and R. Fischer}, journal={2006 10th IEEE International Enterprise Distributed Object Computing … Today's article will cover how an architecture comes to existence and who within the enterprise creates and owns the architecture. They are used by projects teams during the whole duration of IT projects and help implement these projects according to the pre-agreed requirements. They may be either developed at once in a proactive manner, or produced reactively on an as-necessary basis, i.e. Now I will describe each of these essential EA artifacts in detail. Since all planning decisions regarding the future require the discussion and consensus between their stakeholders, these EA artifacts are always developed or updated collaboratively by all relevant stakeholders and represented in formats convenient for these stakeholders. The better and more thoroughly researched your system is, the bigger benefit you will get out of what you have. Duality of EA artifacts can be considered as one of the most fundamental mechanisms underpinning an EA practice and enabling effective collaboration between diverse stakeholders. Most EA artifacts covering wider scopes beyond specific IT initiatives or projects tend to be permanent EA artifacts, Temporary EA artifacts are short-lived EA artifacts often existing for several months or even weeks. From the perspective of their informational contents, various EA artifacts can use different representation formats, provide different levels of detail, cover different scopes, describe different EA domains and focus on different points in time:[5], From the perspective of their lifecycles in an EA practice all EA artifacts can be separated into permanent EA artifacts and temporary EA artifacts:[5], From the perspective of their general meaning in an EA practice all EA artifacts can be separated into decisions EA artifacts and facts EA artifacts:[5][6]. Temporary EA artifacts are created at specific moments for particular purposes, used as intended and then immediately discarded or archived. Unlike decisions EA artifacts, facts EA artifacts do not imply any planning decisions and have no implications for the future. TRMs and guidelines are the most common EA artifacts related to the. For example, for executives’ PowerPoint slides may be the best bet; whereas Visio type artifacts may be useful for peers such as enterprise and solution architects. There is a suggested implementation order for each adversary to assist organisations in building a strong cyber security posture for their systems.
