1What is Togaf Standard ?
Architecture Framework for Enterprise Architecture
What is Togaf Standard ?
Tool Applying Enterprise Architectureassist in acceptance, production, use, and maintenance of EA
Iterative process modelADM method is heart of Togaf to build EA that meet business needs.Supported by best practices and a re-usable architectural assets.
Architecture FrameworkTogaf standard is architecture framework that can be use in conjunction with other frameworks

▷ Why do I need EA ?
▷ What are the business benefits for EA ?
Enterprise Definition
EnterpriseAny collection of organizations that has a common set of goals
Large corporations may comprise multiple enterprises.
Extended Enterprisecomprises 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
Architecture Definition
Definition 2Structure of components, their inter-relationships, and principles and guidelines governing their design and evolution over time
Definition 1Formal Description or Detailed plan Of system at component level to guide its implementation
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 ITThe organizing logic for business processes and IT infrastructurereflecting integration and standardization requirements of firm’s operating model.
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 exploitationof information through IT
Achieving Competitive Advantage
What are business benefits of Enterprise Architecture ? ▷ A more efficient business operation :
1. Lower business operation costs1. Increase organization agility2. Business capabilities shared across organization3. Lower change management costs4. More flexible workforce5. Improved business productivity
▷ A more efficient IT operation :
1. Lower software development, support, and maintenance costs2. Increased portability of applications3. Improved interoperability and easier system and network management4. Improved ability to address critical enterprise-wide issues, such as security5. Easier upgrade and exchange of system components
What are business benefits of Enterprise Architecture ? ▷ Better return on existing investment, reduced risk for future investment :
1. Reduced complexity in business and IT2. Maximum ROI in existing business and IT infrastructure3. Flexibility to make, buy, or out-source business and IT solutions4. 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 systems4. Ability to secure more economic capabilities
3What is Architecture Framework ?
▷ Architecture Framework Definition
▷ Why do I need a framework for enterprise architecture ?
▷ Why Togaf is suitable as framework for EA ?
Architecture Framework Definition
Foundational Structure used for developing range of different architectures
Common VocabularyAnd set of tools
Recommended standards & compliant products
Method for designing Enterprise Target state ( building blocks)
Why do I need a framework for enterprise architecture ?
Future GrowthAllow respond to future needs of business
Simplify & SpeedupArchitecture Development
Complete CoverageEnsure coverage of desired solution
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 futureneeds of business.
Employs Best Practice
Risk Reduction of architecture development
Best Practice framework for Adding Value
