- 1. Enterprise Architecture (IS 112) Introduction to Enterprise Architecture Lecture 1
- 2. OVERVIEW • What is Enterprise Architecture?
- 3. What is Enterprise Architecture? • Enterprise Architecture is a management and technology practice that is devoted to improving the performance of enterprises by enabling them to see themselves in terms of a holistic and integrated view of their strategic direction, business practices, information flows, and technology resources.
- 4. What is Enterprise Architecture? • An Enterprise Architecture (EA) is a conceptual blueprint that defines the structure and operation of organizations. The intent of enterprise architecture is to determine how an organization can effectively achieve its current and future objectives.
- 5. What is Enterprise Architecture? Home Architecture Analogy • Building a house one room at a time without the blueprints for the whole house can lead to a poor result. It is analogous to developing organizations, business units, programs, and systems without an enterprise-wide architecture for reference, as duplication and inefficiency in resources, and a lack of overall agility can result.
- 6. What is Enterprise Architecture? • The success of public, private, and non-profit sector enterprises, particularly those involving multiple internal and external participants like supply chains, increasingly relies on the strategic utilization of resources. • To maximize benefits from business, technology, and human resources, organizations need to adopt an enterprise-wide perspective rather than focusing on individual systems and programs.
- 7. What is Enterprise Architecture? • This shift in approach is known as Enterprise Architecture, which involves a high-level, strategic view of the entire entity and employs a structured framework for the analysis, planning, and development of all resources within that entity. • The word ‘enterprise’ implies a high-level, strategic view of the entire entity, while the word ‘architecture’ implies a structured framework for the analysis, planning, and development of all resources in that entity.
- 8. What is Enterprise Architecture? • Enterprise Architecture (EA) is encapsulated in the equation EA = S + B + T, where EA stands for Enterprise Architecture, and it involves a holistic approach to IT planning driven by strategic goals and business requirements. • The equation breaks down EA into three key components: Strategy, Business, and Technology. This representation aims to emphasize the distinctiveness of EA in contrast to other types of IT planning.
- 9. What is Enterprise Architecture? Enterprise Architecture as a Meta-Discipline • Enterprise Architecture (EA) is positioned as a meta-discipline that serves as the authoritative reference, a source of standards for processes and resources, and a provider of designs for future operating states within an organization. • It is considered THE architecture of the enterprise, covering all elements and aspects. The use of a single, comprehensive reference is crucial to prevent waste and duplication in large organizations and to address the challenges arising from the "battle of best practices" and competition between sub- architectural domains.
- 10. What is Enterprise Architecture? Enterprise Architecture as a Meta-Discipline • Developing an enterprise-wide architecture using EA methods is highlighted as a unique and valuable undertaking. EA is holistic, functioning as an umbrella or "meta-context" for all other management and technology best practices. • It creates abstract views, analyses, and models of the current or future enterprise, aiding in better planning and decision-making. EA goes beyond technology planning, incorporating strategic planning as the primary driver and business planning as the source of program and resource requirements.
- 11. What is Enterprise Architecture? Enterprise Architecture as a Meta-Discipline • In addressing the "battle of the best practices," where organizations face decisions on which practices to adopt for quality, agility, efficiency, risk management, and new technologies, EA serves as the highest-level discipline and authoritative reference. • By being the architecture of the organization in all dimensions, EA eliminates the dilemma of deciding which best practices to adopt, providing a framework for making rational decisions, understanding coverage, and managing relationships between practices.

- 13. What is Enterprise Architecture? The Enterprise Architecture Approach • For an EA approach to be considered to be complete, the six core elements shown in figure below that must be present and work synergistically together.
- 14. What is Enterprise Architecture? The Enterprise Architecture Approach Governance • The first core element is “Governance” which identifies the planning, decision-making, and oversight processes and groups that will determine how the EA is developed and maintained, accomplished as part of an organization’s overall governance.
- 15. What is Enterprise Architecture? The Enterprise Architecture Approach Methodology • The second core element is “Methodology” which are specific steps to establish and maintain an EA program, via the selected approach.
- 16. What is Enterprise Architecture? The Enterprise Architecture Approach Framework • The third core element is “Framework” which identifies the scope of the overall architecture and the type and relationship of the various sub-architecture levels and threads. Not all frameworks allow for sub-domains or are able to integrate strategy, business, and technology planning.
- 17. What is Enterprise Architecture? The Enterprise Architecture Approach Artifacts • The fourth core element is “Artifacts” which identifies the types and methods of documentation to be used in each sub-architecture area, including strategic analyses, business plans, internal controls, security controls, and models of workflow, databases, systems, and networks. This core element also includes theonline repository where artifacts are stored.
- 18. What is Enterprise Architecture? The Enterprise Architecture Approach Standards • The fifth core element is “Standards” which identify business and technology standards for the enterprise in each domain, segment, and component of the EA. This includes recognized international, national, local, and industry standards as well as enterprise-specific standards.
- 19. What is Enterprise Architecture? The Enterprise Architecture Approach Best Practices • The sixth core element is “Associated Best Practices” which are proven ways to implement parts of the overall architecture or sub- architectures, in context of the over-arching EA.
