TOGAF Classroom Series - M1 intro-ea-togaf

  1. 1. Introduc)on to Enterprise Architecture & TOGAF Module 1
  2. 2. Module Objec)ves • To provide an overview of Enterprise Architecture and TOGAF, an Open Group Standard. • Enterprise Architecture • TOGAF – The Enterprise Architecture Framework • The Open Group • Summary
  3. 3. What is an Enterprise? • A collec@on of organiza@ons that share a common set of goals • Large corpora@ons may include mul@ple enterprises • “Extended Enterprise” may include partners, suppliers and customers
  4. 4. What is an Architecture? • The art or prac@ce of designing and construc@ng systems with • its components • their rela@onships to each other and the environment • and the principles governing its design and evolu@on
  5. 5. What is Enterprise Architecture? • An enterprise architecture (EA) is a conceptual blueprint that defines the structure and opera@on of an organiza@on. • The intent of an EA is to determine how an organiza@on can most effec@vely achieve its current and future objec@ves.
  6. 6. Sinan the Architect
  7. 7. What is Enterprise Architecture?
  8. 8. EA in a Nutshell… AS IS / CURRENT STATE TO BE / FUTURE STATE
  9. 9. Why Enterprise Architecture? • Effec@ve management and exploita@on of informa@on through IT is key to business success • Good informa@on management = compe@@ve advantage • Current IT systems • fragmented, duplicated • poorly understood, not responsive to change • tac@cal developments rather than a strategic plan
  10. 10. Why Enterprise Architecture?
  11. 11. Pressure to Develop EA • Laws and regula@ons • Clinger-Cohen Act, Sarbanes-Oxley • More extended enterprises • Audit requirements • Greater publicity to failures • More focus on IT
  12. 12. Business Benefits of EA • A more efficient business opera@on • A more efficient IT opera@on • BeSer return on exis@ng investment (ROI) • Reduced risk for future investment • Faster, simpler and cheaper procurement
  13. 13. The Importance of Governance in EA • An EA is only as good as the decision making framework that is established around it • The Governance Framework depends on • clear authority structure • the right par@cipants •  Who is responsible? Who is involved? Who is accountable?
  14. 14. Enterprise Governance EA Governance •  Governance means establishing and enforcing how people and solu@ons work together to achieve organiza@onal objec@ves. Business Governance IT Governance Supports Aligns EA Governance Supports
  15. 15. Enterprise Architects & Others
  16. 16. What is an Architecture Framework? • A conceptual structure used to develop, implement and sustain an enterprise architecture • It should include • a method for designing target state of the enterprise using building blocks showing their interac@ons • a set of tools and a common vocabulary • recommended standards and compliant tools to implement the building blocks
  17. 17. The Value of a Framework • Provides a prac@cal star@ng point for any project • avoids the ini@al panic • capture what others have found in real life • contains a baseline set of resources for reuse
  18. 18. The Open Group Architecture Framework • TOGAF is a framework - a detailed method and a set of suppor@ng tools - for developing an enterprise architecture • TOGAF is developed and maintained by members of The Open Group.
  19. 19. TOGAF Overview
  20. 20. TOGAF Architecture Domains Business Architecture (Business Processes, Organization, People) Application Architecture (Services) Data Architecture (Data, Information) Technology Architecture (Hardware, Software, Network)

  22. 22. The Open Group… • is an interna@onal vendor and technology neutral consor@um that organiza@ons rely on to lead the development of IT standards and cer@fica@ons • provides guidance and open environment to enable interoperability and vendor-neutrality • membership is open to all enterprises, anywhere in the world, since 1996
