3 What is an enterprise in the context of EA? 3 Open Group defines "enterprise" as any collection of organizations that has a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common goals.

4 What is architecture is in the context of TOGAF? 4 ISO/IEC 42010:2007 defines "architecture" as: "The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution." TOGAF embraces but does not strictly adhere to ISO/IEC 42010:2007 terminology. In TOGAF, "architecture" has two meanings depending upon the context: A formal description of a system, or a detailed plan of the system at component level to guide its implementation The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution

5 Different types of architecture 5 Business Architecture defines the business strategy, governance, organization, and key business processes Business Architecture Data Architecture describes the structure of an organization's logical and physical data assets and data management resources Application Architecture provides a blueprint for the individual application to be deployed, their interactions, and their relationships to the core business processes of the organization Data Architecture Application Architecture Technology Architecture describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. This includes IT infrastructure, middleware, networks, communications, processing, standards Technology Architecture

8 Objectives of TOGAF ADM phases 8 Determine and establish the Architecture Capability Ensure that the architecture lifecycle is maintained Ensure that the Architecture Governance Framework is executed Ensure that the enterprise Architecture Capability meets current requirements Develop a high-level aspirational vision of the proposed enterprise architecture Obtain approval for a Statement of Architecture Work Ensure conformance with the Target Architecture by implementation projects Perform appropriate Architecture Governance functions for the solution Develop the Target Business or Data or Application or Technology Architecture Identify candidate Architecture Roadmap components Finalize the Architecture Roadmap and the supporting Implementation and Migration Plan Ensure that the Implementation and Migration Plan is coordinated with the enterprise s overall change portfolio Generate the initial complete version of the Architecture Roadmap Determine whether an incremental approach is required Manage architecture requirements identified during any execution of the ADM cycle or a phase Ensure that relevant architecture requirements are available for use by each phase

10 Enterprise Architecture vs IT service management 10 ITIL TOGAF Service management A set of specialized organizational capabilities for providing value to customers in the form of services IT service management (ITSM) The implementation and management of quality IT services that meet the needs of the business In TOGAF, "architecture" has two meanings depending upon the context: A formal description of a system, or a detailed plan of the system at component level to guide its implementation The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution ITIL is a registered trademark of AXELOS Limited TOGAF is a registered trademark of The Open Group in the United States and other countries.

11 Service definitions 11 ITIL Service A means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs and risks IT Service A service provided by an IT service provider. An IT service is made up of a combination of information technology, people and processes TOGAF ITIL is a registered trademark of AXELOS Limited TOGAF is a registered trademark of The Open Group in the United States and other countries. Business Service Supports business capabilities through an explicitly defined interface Explicitly governed by an organization Information System Service The automated elements of a business service An information system service may deliver or support part or all of one or more business services Platform Service A technical capability required to provide enabling infrastructure that supports the delivery of applications

12 TOGAF vs ITIL 12 ITIL concentrates in IT services that support business services Planning, developing, implementing, operating and improving IT services IT service management capability Architecture design is one of the service design aspects in ITIL ITIL refers especially to Data/Information, Application and IT infrastructure architectures but also to Service and Environmental architectures TOGAF concentrates in EA that supports the business goals Planning, developing, governing the implementation and operation and improving Architecture that describes how the enterprise needs to operate to achieve the business goals Architecture Capability TOGAF refers to IT Service Management and ITIL When building Architecture Capability, in Implementation Governance and in Architecture Change Management TOGAF does not go into details of ITSM coordination

13 TOGAF vs ITIL 13 Both are based on best practices Both should be tailored for each organization Business alignment was added into the later versions of both frameworks Both use Deming Cycle as the method of improvement Though it is not specifically mentioned in TOGAF ADM ITIL goes much deeper into guiding how continual improvement is done

14 Different perspectives 14 ITIL concentrates in managing IT services Business architecture is not in scope of ITIL Business architecture is one of the TOGAF architecture domains Service transition and service operation are part of ITIL service lifecycle Actual solution deployment and operation is not in scope of TOGAF
