What standards and reference models need to be considered? The Architecture Definition Document is the deliverable container for the core architectural artifacts created during a project and for important related information. Rather, it is recommended that external references be used where possible; for example, the strategic plans of a business should not be copied into a Request for Architecture Work, but rather the title of the strategic plans should be referenced. The one unstoppable trend that has defined the history of solution architecture. It contains the definitions of terms used throughout this standard. The Statement of Architecture Work defines the scope and approach that will be used to complete an architecture development cycle. Enter Solution Architecture HP uses a well-proven method for SOLUTION ARCHITECTURE to develop architecture for initiatives, programs or projects that must be conceived, designed, contracted, built, deployed and evolved. Greefhorst and Proper (2013) An architecture of a solution, where a solution is a system that offers a coherent set of functionalities to its environment. In their turn, principles may be just one element in a structured set of ideas that collectively define and guide the organization, from values through to actions and results. The TOGAF glossary distances EA from Solution Architecture. Implementation Factor Assessment and Deduction matrix, including: Consolidated Gaps, Solutions, and Dependencies matrix, including: Criteria measures of effectiveness of projects, Objective of the Statement of Architecture Work. The Architecture Definition Document spans all architecture domains (business, data, application, and technology) and also examines all relevant states of the architecture (baseline, transition, and target). The formality and detail of any frameworks adopted should also align with other contextual factors for the enterprise, such as culture, stakeholders, commercial models for enterprise architecture, and the existing level of Architecture Capability. This Capability Assessment can be examined on several levels: Typical contents of a Capability Assessment are: During implementation of an architecture, as more facts become known, it is possible that the original Architecture Definition and requirements are not suitable or are not sufficient to complete the implementation of a solution. TOGAF is an Open Group framework used by 90,000+ practitioners worldwide to design, plan and implement enterprise architecture and solution architecture. In the current age of digital transformation, your business requirements are increasingly defined by your customer. Message Tasks. The Implementation Governance Model ensures that a project transitioning into implementation also smoothly transitions into appropriate architecture governance. The Software Architecture Definition (SAD) document describes the subsystems and components of the solution by presenting a number of architectural views. Architecture Contracts are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture. 1.3 Purpose Typically includes: * Solution Overview * Although the framework is more widely used within the Enterprise Architecture community, the fact is that the Open Group framework is designed to be used by any architecture community, … Business Transformation Readiness Assessment, including: Impact assessment of the proposed change, including: Stakeholder priority of the requirements to date, Phase to lead on requirements prioritization, Results of phase investigations and revised priorities, Recommendations on management of requirements, Identification of stakeholders and grouping by communication requirements, Identification of communication needs, key messages in relation to the Architecture Vision, communication risks, and Critical Success Factors (CSFs). Typical contents of an Architecture Vision are: Business principles, business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. In these circumstances, a Change Request may be submitted in order to kick-start a further cycle of architecture work. Also, it is not suggested that these descriptions should be followed to the letter. This Solution Architecture Overview document is used: - To provide a contextual technology framework and diagrams that will underpin the desired application solution. See Part III, 23. The Open Group Architecture Framework (TOGAF) is one of the most widely accepted methods for developing enterprise architecture. Providing an Architecture Vision also supports stakeholder communication by providing a summary version of the full Architecture Definition. Project and portfolio breakdown of implementation: Allocation of work packages to project and portfolio, May include impact on existing portfolio, program, and projects, Benefits of migration, determined (including mapping to business requirements), Governance checkpoints and success/failure criteria, Maturity assessment, gaps, and resolution approach, Roles and responsibilities for architecture team(s), Budget information, financial constraints, External constraints, business constraints, Current architecture/IT system description, Description of resources available to developing organization, Architecture project request and background, Architecture project description and scope, Roles, responsibilities, and deliverables, Tailored architecture content (deliverables and artifacts). This differs from enterprise architecture that may include long term roadmaps that take many years to implement. Successful implementation of these agreements will be delivered through effective architecture governance (see Part VII, 50. Summary views necessary for the Request for Architecture Work and the Version 0.1 Business, Application, Data, and Technology Architectures created; typically including: Reference to Draft Architecture Definition Document. This tailoring will include integration with project and process management frameworks, customization of terminology, development of presentational styles, selection, configuration, and deployment of architecture tools, etc. A Transition Architecture shows the enterprise at an architecturally significant state between the Baseline and Target Architectures. Architecture maturity assessment, including: Architecture governance processes, organization, roles, and responsibilities, Breadth, depth, and quality of landscape definition with the Architecture Repository, Breadth, depth, and quality of standards definition with the Architecture Repository, Breadth, depth, and quality of reference model definition with the Architecture Repository. For example architecture continuum and solution continuum, architecture building block and solution building block. This type of deliverable is often used for approvals and governance activities. It provides a summary of the changes to the enterprise that will accrue from successful deployment of the Target Architecture. According to TOGAF, a widely used reference framework for Enterprise Architecture, the Business Architecture “describes the product and/or service strategy, and the organizational, functional, process, information, and geographic aspects of the business environment”. These include the Conceptual, Logical, Physical, Monitor and Update, and the Transition Phases. Figure 1-1: Structure of the TOGAF Standard. “Physical elements in an enterprise architecture may still be considerably abstracted from Solution Architecture, design, or implementation views.” And it defines Solution Architecture in relation to one business process or one project. The Statement of Architecture Work is typically the document against which successful execution of the architecture project will be measured and may form the basis for a contractual agreement between the supplier and consumer of architecture services. Architecture documentation and models from the enterprise's Architecture Repository; see Part IV, 37. Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation. There are six parts to this document: PART I (Introduction) This part provides a high-level introduction to the key concepts of Enterprise Architecture and in particular the TOGAF approach. Typical contents of a Communications Plan are: Once an architecture has been defined, it is necessary to govern that architecture through implementation to ensure that the original Architecture Vision is appropriately realized and that any implementation learnings are fed back into the architecture process. Identification of mechanisms that will be used to communicate with stakeholders and allow access to architecture information, such as meetings, newsletters, repositories, etc. The Architecture Requirements Specification provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture. For purposes of this document, Solution Architecture is defined as: A program-level solution vision and architecture description consisting of abstract solution building blocks. Furthermore, the document describes the context, has a glossary and references to other resources or resources that have been used in the model. The IT4IT vision is a vendor-neutral Reference Architecture for managing the business of IT and underpins the important work done with IT frameworks such as TOGAF® 9, COBIT® and ITIL®. Architecture Principles for guidelines and a detailed set of generic architecture principles, including: The Architecture Repository acts as a holding area for all architecture-related projects within the enterprise. Effective communication of targeted information to the right stakeholders at the right time is a critical success factor for enterprise architecture. The following are illustrative examples of solution architecture. This is the table of contents and introduction to the book Introduction to Solution Architecture. The content framework provides a structural model for architectural content that allows the major work products that an architect creates to be consistently defined, structured, and presented. In these circumstances, it is necessary for implementation projects to either deviate from the suggested architectural approach or to request scope extensions. In terms of TOGAF and the Enterprise Continuum, and under certain circumstances, any combination of enterprise, enterprise solution and solution architect may be utilized as part of your team. However the focus is not on frameworks but on delivering business value and on standards and artefacts that contribute directly to that goal. Within a chapter you can select Previous and Next at the top and bottom of the page to move to the previous or next chapter, or select Home to return to the welcome page. 36.2.6 Architecture Requirements Specification, 36.2.9 Business Principles, Business Goals, and Business Drivers, 36.2.14 Implementation and Migration Plan, 36.2.16 Organizational Model for Enterprise Architecture, A system of continuous monitoring to check integrity, changes, decision-making, and audit of all architecture-related activities within the organization, Adherence to the principles, standards, and requirements of the existing or developing architectures, Identification of risks in all aspects of the development and implementation of the architecture(s) covering the internal development against accepted standards, policies, technologies, and products as well as the operational aspects of the architectures such that the organization can continue its business within a resilient environment, A set of processes and practices that ensure accountability, responsibility, and discipline with regard to the development and usage of all architectural artifacts, A formal understanding of the governance organization responsible for the contract, their level of authority, and scope of the architecture under the governance of this body, Architecture and strategic principles and requirements, Architecture development and management process and roles, Architecture delivery and business metrics, Service architecture (includes Service Level Agreement (SLA)). The license is free to any organization wishing to use the TOGAF standard entirely for internal purposes (for example, to develop an information system architecture for use within that organization). What is an appropriate style, level of formality, and amount of detail for the architecture project to fit with the culture and capability of the IT organization? But I don't quite understand what's the differences between them in TOGAF. The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture. This is the first of the three TOGAF phases that produce detailed architecture descriptions for the Architecture Definition Document. When not acquiring esoteric and useless facts, Richard is mostly found installing tricky Minecraft mods for his son and his friends. Interfaces with governance models and other frameworks: In the main Contents frame in the left margin of the page, click the relevant hyperlink to load the Contents List for that Part of the TOGAF document or go direct to a chapter within the document. New requirements are a challenge, and a challenge requires a solution. Within organizations that have established architecture functions, there is likely to be a governance framework already in place, but specific processes, organizations, roles, responsibilities, and measures may need to be defined on a project-by-project basis. A Brief Introduction to Solution Architecture What is Solution Architecture? The content and structure of business context for architecture is likely to vary considerably from one organization to the next. Each phase consists of specific SA activities that generate (or maintain) a set of solution architecture deliverables in the form of models that define the project solution. The Implementation and Migration Strategy identifying the approach to change is a key element of the Implementation and Migration Plan. In general, all the information in this document should be at a high level. Tailoring at this level will select appropriate deliverables and artifacts to meet project and stakeholder needs. Early agreement on the outcome enables the architects to focus on the detail necessary to validate feasibility. This document presents an enterprise architecture framework for the University – the „Birmingham Enterprise Architecture Framework‟ – based on TOGAF version 9. An Architecture Requirements Specification will typically form a major component of an implementation contract or contract for more detailed Architecture Definition. Transition Architectures necessary to effectively realize the Target Architecture are identified as intermediate steps. Svyatoslav Kotusev, an independent researcher, questions whether the Open Group Architecture Framework (TOGAF) is the industry standard framework that enterprise architects really deserve. What are the risks to transformation, cultural barriers, and other considerations to be addressed beyond the basic capability gap? The following sections provide example descriptions of deliverables referenced in the ADM. Are they maintained and accurate? The Architecture Roadmap highlights individual work packages' business value at each stage. It was released as a reference model for enterprise architecture, offering insight into DoD’s own technical infrastructure, including how it’s structured, maintained and configured to align with specific requirements. Identification of a communications timetable, showing which communications will occur with which stakeholder groups at what time and in what location, Software services and middleware checklist. And a lot of challenges are not purely resolved with software, or by writing code. TOGAF is an open framework, providing a practical, definitive and proven step-by-step method for developing and maintaining enterprise architecture. As mentioned above, the Architecture Requirements Specification is a companion to the Architecture Definition Document, with a complementary objective: Typical contents of an Architecture Requirements Specification are: The Architecture Roadmap lists individual work packages that will realize the Target Architecture and lays them out on a timeline to show progression from the Baseline Architecture to the Target Architecture. What architectural assets are currently in existence? The Open Group covers a diverse group that spans all sectors of the ICT community ICT customers, systems and solutions suppliers, tool vendors, integrators and consultants, as well as academia and researchers. Development of a Communications Plan for architecture allows for this communication to be carried out within a planned and managed process. Most Common DevOps Interview Questions and Answers, Video: Lean and the 5S Methodology – A Short Guide, Video: BPMN Process Modelling – A Brief Guide, Benefits of Using a Learning Management System (LMS), Good e-Learning and Docebo Win Bronze at Brandon Hall Group Excellence Awards. Core BPM Principles and BPMN 2.0 – Processes as Assets, Common BPMN Modeling Mistakes and Best-Practices: Basic Events, What Exactly Is IT4IT? A Brief History of Solution Architecture. Structured Approach to Solution Architecture Alan McSweeney 2. See Part V, 41. However, each element should be considered carefully; ignoring any input or output item may cause problems downstream. How to Pass a Enterprise Architecture Project Review. Richard is the Portfolio Manager and one of the Senior Instructional Designers at Good e-Learning. Solution Architecture Example: Nouveau Health Care Claim Payment Solution Architecture This document presents an example Solution Architecture document. This document describes the baseline and target enterprise architecture, and gap analysis for your project. This chapter provides descriptions of deliverables referenced in the Architecture Development Method (ADM). One of the standards is the Open Group Architecture Framework (TOGAF). Architecture Definition Document is one of the TOGAF deliverables you can create with the TOGAF tool. The TOGAF 9 meta-model has been extended to include an SOA-specific “Information Entity” from which the Business Vocabulary Catalog and an Information Component Model are derived. TOGAF® 9 Template Artifacts and Deliverables, Set 2 Templates provided by The Open Group Adoption Strategies Working Group to accompany W102 and W103 This is an example set of templates for the TOGAF 9 standard. Gartner (2013) A solution architecture (SA) is an architectural description of a specific solution. The repository allows projects to manage their deliverables, locate re-usable assets, and publish outputs to stakeholders and other interested parties. Many factors that lie outside the consideration of architecture discipline may nevertheless have significant implications for the way that architecture is developed. Building Blocks. Introduction) identifies deliverables that are produced as outputs from executing the ADM cycle and potentially consumed as inputs at other points in the ADM. Other deliverables may be produced elsewhere and consumed by the ADM. Deliverables produced by executing the ADM are shown in the table below. What are the likely implications of conducting the architecture project in terms of design governance, operational governance, skills, and organization structure? This Business Architecture document delivers this overview. Before embarking upon a detailed Architecture Definition, it is valuable to understand the baseline and target capability level of the enterprise. The Architecture Definition Document provides a qualitative view of the solution and aims to communicate the intent of the architect. Requests for Architecture Work can be created as an output of the Preliminary Phase, a result of approved architecture Change Requests, or terms of reference for architecture work originating from migration planning. How Do I Use COBIT® 2019 in a Way That Suits... BPMN 2.0 Message Events Vs. 16 Solution Architect Anti-patterns. The Architecture Definition Document is a companion to the Architecture Requirements Specification, with a complementary objective: Typical contents of an Architecture Definition Document are: Principles are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission. Like all architects, the Solution Architect relies on certain fundamental principles, such as the separation of concerns, abstraction, and the creation of conceptual models and formal specifications. Note that not all the content described here need be contained in a particular deliverable. June 12, 2014 2 Solution Architecture Is … − Description of the structure, characteristics and behaviour of a solution − The means by which the solution is defined, delivered, managed and operated • A solution is an answer to a business problem that may or may … Typical contents of a Compliance Assessment are: The Implementation and Migration Plan provides a schedule of the projects that will realize the Target Architecture. The Open Group Architecture Framework (TOGAF) is currently promoted as an industry consensus framework for enterprise architecture (EA) representing the best practice of numerous EA practitioners. Typical contents of an Implementation and Migration Plan are: Once an architecture has been defined, it is necessary to plan how the Transition Architecture that implements the architecture will be governed through implementation. Are there likely to be opportunities to create re-usable assets during the architecture project? To navigate around the document: Downloads of TOGAF®, an Open Group Standard, are available under license from the TOGAF information web site. The TOGAF Content Framework (see Part IV, 33. The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture. Once the framework has been tailored to the enterprise, further tailoring is necessary in order to tailor the framework for the specific architecture project. Typical contents of an Organizational Model for enterprise architecture are: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle. Each view shows a different aspect of the system to address different concerns and is … Architecture Repository for a detailed description of the content of an Architecture Repository. Typical contents of an Implementation Governance Model are: In order for an architecture framework to be used successfully, it must be supported by the correct organization, roles, and responsibilities within the enterprise. The Solution Architect must also ensure that the given solution fits within these. Architecture Contracts. The Implementation and Migration Plan includes executable projects grouped into managed portfolios and programs.
