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. http://pubs.opengroup.org/architecture/togaf9-doc/arch/
  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)
  21. 21. TOGAF Scope • TOGAF emphasizes business goals as architecture drivers, and provides a repository of best prac@ce,
  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 http://www.opengroup.org

Summary • The Open Group Architecture Framework • An effec@ve, industry standard framework and method for enterprise architecture • Complementary to, not compe@ng with, other enterprise frameworks • A repository of best prac@ce • Vendor, tool and technology neutral • A framework and method for achieving the “Boundaryless Informa@on Flow” vision
