1. Enterprise Architecture HOW COMPANIES ARE EXPLOITING INFORMATION TO THROUGH IT

2. Why Enterprise Architecture Definition:EA translates business vision and strategy into change How? By creating, communicating and improving key requirements, principles, models to describe future state Enterprise Architects do what:compose holistic solutions that address the business challenges  Align IT with the business  Support the business by providing the fundamental technology and process structure for an IT strategy What does that mean anyway?

3. Benefits of Enterprise Architecture  IT alignment with business goals – an IT plan that shares the vision of the future  Integration (need for rapid business change means we need business and IT integration) We use methodologies and frameworks to integrate functions, processes, data, locations, people, events and business plans To achieve integration, we use enterprise portals, web services, service oriented architecture (SOA), business process management (BPM) and try to lower the number of interfaces  Change Management  Reduced time to market and increased IT responsiveness  Better access to information across applications and improved interoperability Identify overlapping functional scope and consolidate architectures for: shared enterprise services, applications and information, technologies and data centres

4. Benefits of Enterprise Architecture… continued  Reduced time to market and increased IT responsiveness  Better access to information across applications and improved interoperability  Readily available descriptive representation of documentation of the enterprise  Reduce IT costs by consolidating, standardizing, rationalizing and integrating corporate information systems  More Spending on innovation  Enabling strategic goals via better operational excellence  Customer intimacy (business model, IT systems and operational activities designed to support customer focus strategy)

5. Enterprise Architecture Enterprise Architecture = Strategy + business + technology

6. Enterprise Architecture Current Architecture to future architecture

7. Enterprise Architecture Examples of EA components

8. Enterprise Architecture Evaluating current capabilities and designing future capabilities

9. Enterprise Architecture Phase 1: Goals and Initiatives Goals and initiatives, why does the enterprise exist (mission statement) Where do we intend to be (vision statement) Primary goals (strategic goals) What are the current strategic initiatives How will we measure our success Phase 2: Products and Services Lines of business to support the strategic initiatives and maintenance/housekeeping functions Specific activities/products/services in each line of business How do we measure the success of each line – how does each line contribute to the strategic goals Do we need to re-engineer any of the business or manufacturing processes so that they can fit with the future architecture

10. Enterprise Architecture Phase 3: Data and Information Flows of data within and between activities How can we harmonize, standardize protect this data for efficient sharing How will the data be generated, shared and stored How will the data become useable knowledge Phase 4: Systems and Applications Application systems used and what they need to generate to serve business needs How can IT systems work together Common operating Environment Phase 5: Network and Infrastructure Physical space and utility support requirements to support IT systems
