  2. 2. Basic Concepts Togaf Standard Enterprise Architecture Architecture Framework Architecture Domain Togaf Standard Structure
  3. 3. 1 What is Togaf Standard ? Architecture Framework for Enterprise Architecture
  4. 4. What is Togaf Standard ? Tool Applying Enterprise Architecture assist in acceptance, production, use, and maintenance of EA Iterative process model ADM method is heart of Togaf to build EA that meet business needs. Supported by best practices and a re-usable architectural assets. Architecture Framework Togaf standard is architecture framework that can be use in conjunction with other frameworks
  5. 5. 2 What is Enterprise Architecture ? Enterprise Definition Architecture Definition Enterprise Architecture Definition Why do I need EA ? What are the business benefits for EA ?
  6. 6. Enterprise Definition Enterprise Any collection of organizations that has a common set of goals Large corporations may comprise multiple enterprises. Extended Enterprise comprises the partners, suppliers, and customers, as well as internal business units. Enterprise Can Be Single department Chain of geographically distant organizations linked together by common ownership. Government Agency Whole Corporation Division of a corporation
  7. 7. Architecture Definition Definition 2 Structure of components, their inter-relationships, and principles and guidelines governing their design and evolution over time Definition 1 Formal Description or Detailed plan Of system at component level to guide its implementation
  8. 8. Enterprise Architecture Definition Conceptual blueprint Defines the structure and operation of an organization EA Intent to determine how to achieve current and future objectives of organization Mapping Business into IT The organizing logic for business processes and IT infrastructure reflecting integration and standardization requirements of firms operating model.
  9. 9. Why we need Enterprise Architecture ? Optimize Across Enterprise [fragmented legacy processes into integrated environment ] Responsive To Change Support Delivery of Business Strategy Providing a Strategic Context for IT in response to constantly change of business needs Management and exploitation of information through IT Achieving Competitive Advantage
  10. 10. What are business benefits of Enterprise Architecture ? A more efficient business operation : 1. Lower business operation costs 1. Increase organization agility 2. Business capabilities shared across organization 3. Lower change management costs 4. More flexible workforce 5. Improved business productivity A more efficient IT operation : 1. Lower software development, support, and maintenance costs 2. Increased portability of applications 3. Improved interoperability and easier system and network management 4. Improved ability to address critical enterprise-wide issues, such as security 5. Easier upgrade and exchange of system components
  11. 11. What are business benefits of Enterprise Architecture ? Better returnon existing investment, reduced risk for future investment : 1. Reduced complexity in business and IT 2. Maximum ROI in existing business and IT infrastructure 3. Flexibility to make, buy, or out-source business and IT solutions 4. Reduced risk overall in new investments and their costs of ownership Faster, simpler, and cheaper procurement : 1. Simpler buying decisions, because Information governing procurement is readily available in a coherent plan 2. Faster procurement process, maximizing procurement speed and flexibility without sacrificing architectural coherence 3. Ability to procure heterogeneous, multi-vendor open systems 4. Ability to secure more economic capabilities
  12. 12. 3 What is Architecture Framework ? Architecture Framework Definition Why do I need a framework for enterprise architecture ? Why Togaf is suitable as framework for EA ?
  13. 13. Architecture Framework Definition Foundational Structure used for developing range of different architectures Common Vocabulary And set of tools Recommended standards & compliant products Method for designing Enterprise Target state ( building blocks)
  14. 14. Why do I need a framework for enterprise architecture ? Future Growth Allow respond to future needs of business Simplify & Speedup Architecture Development Complete Coverage Ensure coverage of desired solution
  15. 15. Why Togaf is suitable as framework for EA ? Build workable - economic solutions Address business issues and needs. Consistent , reflects Needs of Stakeholders Gives consideration to current requirements and to future needs of business. Employs Best Practice Risk Reduction of architecture development Best Practice framework for Adding Value
