2. Architecture Vision Objective General Approach Creativity Approach Inputs Steps Business Scenarios Outputs

4. Objectives of Architecture Vision To ensure that this evolution of the architecture development cycle has proper recognition and endorsement from the corporate management of the enterprise. To validate the business principles, business goals, and strategic business drivers of the organization. To define the relevant stakeholders, and their concerns and objectives.

5. Cont…. To define the key business requirements and the constraints. To secure formal approval to proceed. To understand the impact on, and of, other enterprise architecture development cycles going on in parallel.

6. General Approach Starts with receipt of a Request for Architecture work from the sponsoring organization to the architecture organization. It also defines what is in and what is outside the scope of the architecture effort and the constraints that must be dealt with.

7. Cont… Scoping decisions need to be made on the basis of a practical assessment of resource and competence availability. The activity in this phase is concerned with ensuring that the existing principles definitions are current, and clarifying any areas of ambiguity. Otherwise, it entails defining the architecture principles from scratch.

8. Creating the Architecture Vision The Architecture Vision is essentially the architect's "elevator pitch“. The goal is to articulate an architecture vision that enables the business goals, responds to the strategic drivers, conforms with the principles, and addresses the stakeholder concerns and objectives.

9. Inputs Request for Architecture Work Business Strategy, Business Principles, Business Goals and Business Drivers (when pre-existing) Architecture Principles (when pre-existing) Enterprise Continuum - existing architectural documentation (framework description, architectural descriptions, existing baseline descriptions, etc.)

10. Key steps include in this phase Project Establishment Business Principles, Business Goals and Business Drivers Architecture Principles Scope Constraints Stakeholders and concerns, Business Requirements, and Architecture Vision Statement of Architecture Work and Approval

11. Business Scenarios Identify, document and rank the problem Document the business and technical environment Objectives and Measures of Success Human Actors Computer Actors Roles and Responsibilities Refine

12. The outputs of this phase are: Approved Statement of Architecture Work / Project Definition Scope and constraints Refined statements of Business Principles, Business Goals and Strategic Drivers Architecture Principles (if not previously existing) Architecture Vision

13. Cont… Business Scenario Business Baseline Version 1 Technical Baseline Version 1 Business Architecture Version 1 Technical Architecture Version 1

14. View Tools and Languages

15. View Tools and Languages

16. View Tools and Languages Relationship between different architecture views Tools used in developing A standard language enabling interoperability between the tools

17. View and Viewpoints

18. View and Viewpoints A viewpoint is a model or description of the information combined in view.

19. Examples of view and viewpoints

20. Examples of view and viewpoints An aircraft with two different stakeholders The pilot and the air traffic controller

21. View of pilot

22. View of pilot

23. View of pilot Pilot sees the system Pilot sees the passenger Pilot sees the fuel Pilot sees position Pilot sees the vector toward or away from the runway

24. View of the air traffic controller

25. View of the air traffic controller Air traffic controller sees the other planes Air traffic controller sees the air traffic map

26. Shared view of pilot and air traffic controller

27. Shared view of pilot and air traffic controller Both sees the communication model between the pilot and air traffic controller Both sees the vital information of plane

28. Tools of pilot

29. Tools of pilot

30. Tools of pilot Fuel Altitude Speed Location Indicator

31. Tools of air traffic controller

32. Tools of air traffic controller Radar

35. Conclusion : Architecture projects are often undertaken with specific purpose in mind, a specific set of business drivers in the architecture development. Clarifying that purpose, and demonstrating how it will be achieved by the proposed architecture development, is the whole point of the Architecture Vision.
