IEEE Architecture Council Overview ITSC Meeting 06-Dec-2004

What is Enterprise Architecture? Enterprise Architecture - a strategic information asset base, which defines the mission, the information necessary to perform the mission and the technologies necessary to perform the mission, and the transitional processes for implementing new technologies in response to the changing mission needs. An enterprise architecture includes a baseline architecture, target architecture, and a sequencing plan. (from A Practical Guide to Federal Enterprise Architecture) 8-Jul-19

What is Enterprise Architecture At a high level, enterprise architecture can be defined as “…an enterprise-wide, integrating framework which incorporates: Enterprise Business Architecture Enterprise Information Architecture (aka Data Architecture) Enterprise Technology Architecture (aka Infrastructure Architecture) Enterprise Solution Architecture (aka Application Architecture) (ISWorldNet) 8-Jul-19

Why an EA? The primary purpose of an EA is to inform, guide, and constrain the decisions for the enterprise, especially those related to IT investments. The true challenge of enterprise engineering is to maintain the architecture as a primary authoritative resource for enterprise IT planning. This goal is not met via enforced policy, but by the value and utility of the information provided by the EA. (from A Practical Guide to Federal Enterprise Architecture) 8-Jul-19

Why an EA? An EA offers tangible benefits to the enterprise and those responsible for evolving the enterprise. The EA can: Capture facts about the mission, functions, and business strategy in an understandable manner to promote better planning and decision making Improve communication among the business organizations and IT organizations within the enterprise through a standardized vocabulary Provide architectural views that help communicate the complexity of large systems and facilitate management of extensive, complex environments Improve consistency, accuracy, timeliness, integrity, quality, availability, access, and sharing of IT-managed information across the enterprise 8-Jul-19

Business Architecture Identifies the Business strategies, functions, processes, organization and information flow for accomplishing mission of the organization Functionality driven approach rather than Org-chart, location maps etc. 8-Jul-19

Business Architecture Define businesses based on common functional needs Develop process to define common vision and goals and a plan to achieve operational efficiencies using Information technology strategies Develop and define roles and responsibilities to facilitate communication and coordination and a common IT strategy Regular audits of current capabilities and evaluations of business drivers to influence behaviors 8-Jul-19

Information Architecture Data Strategy Defining Major types of data needed to conduct the business Analytical and Operational data needs Common definitions and vocabulary Authoritative source and data migration needs 8-Jul-19

Information Architecture Develop a common enterprise wide data definition Define authoritative data sources Develop business processes & technology to ensure data integrity Understand and develop data to support operational and analytical business needs 8-Jul-19

Technology Architecture It covers all the supporting IT elements that must be operated on a day-to-day basis, together with the tools and processes to monitor and manage them Usually the most clearly defined Technology “Stacks” Example:. Weblogic running on Solaris with Oracle RDBMS 8-Jul-19

Solution Architecture Defines Application and supporting capabilities of software systems to manage the underlying data to meet business and performance needs It begins with the identification of which applications are needed to support the business and carries through the design and construction (or acquisition) and integration of applications 8-Jul-19

Solution Architecture The cataloging of these applications is the definition of the “Building Blocks” project within IT Reuse and assembly of common application architecture components Eventually this will lead to an Application capability reference model Structured across horizontal business areas independent of business functions 8-Jul-19

Steps to develop EA Define a process to promote EA Define current architecture: Continue to take an inventory of where we are today. (Reference Architecture) Understand business and technology drivers Define the future EA (Target Architecture) Plan the trip (Migration Strategy) 8-Jul-19

Our Charter Define IEEE Enterprise Architecture standards Build consensus across departments on common application platforms, tools and infrastructure components Collaborate and build synergies across our technology platforms aligned with our IEEE Goals and Objectives 8-Jul-19

IEEE EAC Mission The mission of the IEEE Enterprise Architecture Council is to create and promote the principles, guidelines, standards and processes for the benefit of IEEE members, clients, volunteers, staff, societies and business areas (the “Enterprise”) by: building Synergies across organizations - in business processes, infrastructure, data definition & migration and applications leveraging existing technical and support infrastructure promoting a culture of re-use leading to decreased time-to-market and lower development costs keeping abreast with upcoming business and technology trends for applicability facilitating the efficient and effective introduction of new technology and business solutions mentoring local steering committees in the adoption of the above in their organizations. 8-Jul-19
