  1. Extended Enterprise Architecture Framework (E2AF)

  2. Agenda • Introduction • E2AF Development Process • E2AF Full Blown • View & ViewPoint • Enterprise Architecture Approach • Win Win Spiral Model • Evaluation • Tool Selection • EA Maturity Model E2AF

  3. Introduction • An enterprise architecture (EA) establishes the organization-wide roadmap to achieve an organization’s mission through optimal performance of its core business processes within an efficient information technology (IT) environment. • besides the choices for an EA framework at the same time choices for supporting methods and techniques has to be made. E2AF

  4. Elements of Frameworks • 3 major elements of every Framework: • Construction • Function • Style • enterprise architecture is dealing with construction and function, without any attention of the style aspect E2AF

  5. Why E2AF • Every complex thing that has to operate as a whole has to be designed as a whole. This to guarantee integration and coherency of all its components and to ensure the whole will operate the way required when it is created. • Organization will be fully benefits from the alignment of business and IT by integrating all enterprise architecture aspect areas into one overall result E2AF

  6. What does it do for us? • Enterprise Architecture results as well as E2AF itself can be used as an Atlas for management to navigate to all relevant topics. • From E2AF, roadmaps can be defined to identify the necessary tasks and activities. • E2AF can show the complexity of elements to be addressed. • E2AF can show the people to be involved in the process. • E2AF shows the relations and dependencies. • E2AF is your Guide in all Architectural Activities. E2AF

  7. E2AF Development Process (1) • Enterprise Architecture environment rules & principles • Business Benefits are leading • Business based choices • Business centric thinking instead of technology centric thinking • Business Principles are mandatory • Business Scenario thinking • Technology enabling by business benefits (Or Technology rationalised by business benefits) E2AF

  8. E2AF Development Process (2) • Translating the rules & principles into a coherent framework • Separation of levels of abstraction • Separate the Strategy from Requirements • Separate Requirements from solutions • Separate solutions from implementations • Separate implementations from transformations • Enterprise Architectures exist at different abstraction levels E2AF

  9. E2AF Development Process (3) • Combining aspect areas with abstraction levels • Adding Viewpoints to the framework • Integrating all these elements into a Framework E2AF

  10. E2AF Full Blown E2AF

  11. Separation of concerns • Contextual (Why?) • Environmental (With Who?) • Conceptual (What?) • Logical (How?) • Physical (With what?) • Transformational (When?) E2AF

  12. Decomposition of the Enterprise • Business • Information • Information Systems • Technology Infrastructure E2AF

  13. ViewPoint: defines the perspectives from which views are taken. From an extended enterprise perspective these viewpoints are addressing generic and common concerns covering the whole enterprise. Views: are representations of the overall enterprise architecture that are meaningful to all stakeholders in and outside the organization. Enterprise Architectural Viewpoints Security Governance The impact of viewpoints should be incorporated in the extended enterprise architecture results at all levels. View & ViewPoint E2AF

  14. Relations E2AF

  15. Enterprise Architecture Approach E2AF

  16. The E2AF WinWin Spiral Model E2AF

  17. Effective Factors on EA E2AF

  18. when is an Enterprise Architecture Good Enough ? • “An Enterprise Architect knows he has achieved the perfect solution not when there is nothing left to add, but when there is, nothing left to take away.” [Saint-Exupery] • Enterprise Architecture Score Card developed by Jaap Schekkerman E2AF

  19. Enterprise Architecture Score Card E2AF

  20. Validation Approach E2AF

  21. Tool Selection (1) • tools basic functionality: • Methodologies and Models; • Model Development Interface; • Tool Automation; • Extendibility and Customization; • Analysis and Manipulation; • Repository; • Deployment Architecture; • Costs and Vendor Support. E2AF

  22. Tool Selection (2) • tool’s utility to different professionals: • Enterprise Architects; • Strategic Planners; • Enterprise Program Managers. E2AF

  23. Tool Selection (3) • The purpose of adopting an EA Tool: • Supporting decision making of management requires another level of detail in models and diagrams then supporting application development. • Tool List & Candidate Tool Requirements Checklist [4. Enterprise Architecture Tool Selection Guide] • Gartner's Magic Quadrant for business process analysis 2006 E2AF

  24. Some Tools E2AF

  25. EA Maturity Model • IFEAD Extended Enterprise Architecture Maturity Model (E2AMM) • path for enterprise architecture • procedural improvements within an organization E2AF
