What is EA?

  • enabling the delivery of business capabilities
  • stewarding technology resources to their most efficient and effective use
  • minimizes unnecessary duplication and complexity in the technical environment
  • accelerates delivery of critical business capabilities
  • improves integration quality
  • supports innovation, employee productivity, enterprise collaboration
  • include technical, application, information and business architecture
  • align IT investments with long-term strategy
  • reduce technology lifecycle risk
  • enable effective delivery of adaptive solutions and high quality information

EA’s job

  • Across the enterprise to enable business outcomes (Enterprise-Wide Focus)
  • Throughout the technology portfolio to ensure technologies work together (Technology Centric)
  • Over time as technologies and the demands of the business evolve (Strategic Vision)

EA vs. project

  • EA is more on Enterprise-wide + Biz strategy driven
  • Project is more on local business + tactical driven

Communities of Practice (CoP)

  • technical forums for discussing architecture and standards topics and making appropriate recommendations.
  • like slack?

Priorities and Mission Statement

strategic planning <--mutually reinforce--> project engagement

EA operating priorities:

  • Establish clear criteria for EA involvement
  • Architect for business outcomes through business capability enablement
  • Equip governance to support speed and scale

EA Function: We drive technology vision and direction in support of evolving business priorities through leadership, discipline and focus on value delivery.

EA will be delivering on its mandate by:

  • Establishing a set of easy-to consume EA services.
  • Tying delivery roles/teams business outcomes and not just architecture expertise. Also, optimize the use of EA resources by establishing a principled approach to determine the scope and depth of EA’s involvement.
  • Establishing enterprise architecture as a broadly-practiced management discipline through collaboration and self-service as much as possible.
  • Providing non-architects with simple tools that save time, improve project success rates, and reduce governance friction.
  • Using the business capability model to help tier EA’s activities to meet differing, concurrent business objectives (e.g. cost efficiency in commoditized capabilities and agility and flexibility in core business capabilities).

EA definition

  1. ANSI/IEEE Std 1471-2000: “The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution.”
  2. Cap Gemini: “Enterprise Architecture is the description and visualization of the structure of a given area of contemplation, its elements and their collaborations and interrelations links vision, strategy and feasibility, focusing on usability durability and effectiveness. Architecture enables construction, defining principles, rules, standards and guidelines, expressing and communicating a vision”
  3. Forrester, Gene Leganza, 2001: “Enterprise architecture consists of the vision, principles and standards that guide the purchase and deployment of technology within an enterprise”
  4. Gartner Group: “Enterprise architecture (EA) is the process of translating business vision and strategy into effective enterprise change by creating, communicating, and improving the key principles and models that describe the enterprise’s future state and enable its evolution.”
  5. Gartner Group, Philip Allega: “Enterprise architecture is the process that interweaves business and IT together”
  6. Institute for Enterprise Architecture Development: “Enterprise Architecture is about understanding all of the different elements that go to make up the enterprise and how those elements interrelate” (link is external)
  7. MIT Center for Information Systems Research: “Enterprise Architecture is the organizing logic for key business processes and IT capabilities reflecting the integration and standardization requirements of the firm’s operating model.”
  8. The ArchiMate Foundation: “A coherent whole of principles, methods, and models that are used in the design and realization of an Enterprise's organizational structure, business processes, information systems, and infrastructure”
  9. The Open Group: “By being inclusive with all other management frameworks, EA is a discipline that helps the Enterprise define , develop and exploit the boundaryless information flow (BIF) capabilities in order to achieve the Enterprise's Strategic Intent.”
  10. US Federal Enterprise Architecture Framework (FEAF): “Enterprise architecture is a management practice to maximize the contribution of an agency's resources, IT investments, and system development activities to achieve its performance goals. Architecture describes clear relationships from strategic goals and objectives through investments to measurable performance improvements for the entire enterprise or a portion (or segment) of the enterprise”
