TOGAF provides a framework for continuous change that links strategic direction and business value. Manages complexity, risks and supports change. Optimises processes into an integrated environment that is responsive to change and is supportive of the delivery of the business strategy and mission. Provides enterprises a strategic context for the evolution and reach of digital capability in response to the changing needs of the business environment. Achieves a balance between business transformation and operational efficiency. Enables business units to innovate for business goals and competitive advantage. Enables an integrated strategy with synergies across the enterprise and beyond Governs, directs and controls, the change activity to realise the expected value. Describes the current and future state of an enterprise as well as the gaps Documents processes around data that can be easily understood and managed Provides an approach to reach the target state that performs trade-offs and value realisation for decisions.

The TOGAF Standard - Structure and Documents

Overview The Architecture Repository is a central repository for all architecture artifacts and work products. It stores different classes of architectural output at different levels. Part of the Enterprise Repository of artifacts. This is often implement by modelling software (e.g. BizzDesign), analytic tools, file repositories or document/content management systems. Architecture Landscape The architectural representation of assets deployed within the enterprise at a particular point in time - This will reflect the baseline, transition(s) and target states often at multiple levels of detail. ...

Building Blocks Overview These are potentially re-usable components that can be used to deliver an Architecture. TOGAF will group these into the abstract Logical - Application Building Blocks and the Physical Building Blocks - Solution Building Blocks (SBB). Without being too prescriptive, a building block should meet the following criteria: Is a package of functionality defined to meet a business need or capability. It should be recognisable as a discrete thing. Should normally correspond to one of the types defined in the Enterprise Metamodel - Actor, Business Service, Application or Data Entity. Can be defined at various levels of detail depending on the objective of the Architecture and also the Phase. There is a general benefit of composing functionality through building blocks in that it should improve integration and interoperability through defined interfaces and contracts. It may also improve reusability and flexibility through the creation of new re-usable applictions or components. ...

TOGAF Architecture Development Method (ADM) TOGAF uses a “crop circle” diagram to show the progress of the different phases of the ADM. Prior to commencing the ADM, the Preliminary phase should be completed, which will provide the framework and principles for the ADM. The phases may occur in parallel. The circle theme is used to show the possible iterations of the architecture over time. Requirements are in the centre as they will be updated and managed throughout the ADM phases. ...

Purpose The primary purpose of Architecture Principles are: Enable decision-making - it is important to set precedence during trade-off discussions and authority of tie-breaking if it must occur Align the enterprise - principles take subjectivity and bias out of the equation and drive critical conversations that are objective and aligned to the enterprise’s values Governance - how will the enterprise ensure that the right decisions are surfaced at the right time and with the right decision-makers, and, moreover, how to monitor the decisions and approach taken to arrive at the decision? Values and Culture - provide a better understanding about the enterprise’s culture and values; provide an approach and insight into how well the enterprise reacts to change Characteristics The following are some primary characteristics of Architecture Principles: ...

Enterprise Architecture Transformation: A Structured Approach In today’s rapidly evolving business landscape, organisations require a systematic methodology to align technology initiatives with strategic objectives. The comprehensive framework depicted in our architectural transformation roadmap provides a disciplined approach to this challenge. The Six Phases of Architectural Transformation 1. Strategy Definition Capture & Define Business & Technology Strategy for each capability The journey begins by clearly articulating business goals and technical requirements. This foundational phase establishes the vision that will drive all subsequent activities, including the identification of business objectives, architectural principles, and requirements that will guide the transformation. ...

Architecture Abstraction The concept of abstraction is a means to enable reasoning about an Architecture. Dividing a problem into smaller problems is a common approach to making an Architecture easier to model and create solutions for. We can have one or more of the abstraction levels at each of the Strategic, Segment or Capability Architecture. Introduction We can consider multiple simple questions in order to structure the approach to abstraction: ...

Architecture Board The cross-enterprise architecture board is the highest level of architecture governance and is represnted by architecture stakeholders. Role The Group of executives responsible for the review and maintenance of the architecture and to oversee the implementation of the strategy within Phase H - Architecture Change Management of the ADM. Possesses identifiable and articulated responsibilities, decision-making capabilities, remit and authority limits. Distinguishes between local (domain experts, line responsibility) and global (organisation-wide responsiblity) representatives in larger enterprises Scope may be Global, Regional or Business Line General Responsibilities The board is reponsible and accountable for achieving different goals: ...

Architecture Capability The Enterprise Architecture is a business capability that supports 4 different types of business capabilities: Architecture to Support Strategy Architecture to Support Portfolio Architecture to Support Projects Architecture to Support Solution Delivery Overview Posseses organisation structures with roles, responsibilities, skills and processes for Enterprise Architecture work. Treated like any other operational unit within the business. Establishes management capabilities for the architecture capability. Purposes Purpose Capability Description Architecture to Support Strategy Provide Target Architecture and Roadmaps Change & synergies, governance Multiple programmes and portfolios Architecture to Support Portfolio Ensure alignment, synergies between architectures and governance Single portfolio of projects Support of Cross-functional and multi-phase architectures Architecture to Support Projects Integration between projects Integration between projects Value and Compliance per project Support the project delivery method Architecture to Support Solution Delivery Support the solution deployment for an architecture Governance Framework for change Single project or a significant part of a project Architecture to Support Strategy Provide end-to-end Target Architecture Develop Roadmaps for change over a period of 3 to 10 years ...
