University of California, Irvine (Administrative Computing Services) TechnoExpo, Our Challenges  Hundreds of systems - IBM Mainframe, Solaris, Windows  Users use disparate systems, user interfaces = Training  New compliance regulations/ security threats  Staffing resources  Increasing complexity and technology choices for solutions  Workflow, Imaging...  Governance to control proliferating IT solutions  Extraction of common requirements and solutions across projects EA Initiative Identified

University of California, Irvine (Administrative Computing Services) TechnoExpo, Overview: What is EA?  A strategic asset repository which defines the current and target architecture environments.

University of California, Irvine (Administrative Computing Services) TechnoExpo, EA Planning Consists of  A standard methodology or framework  A model  A repository of knowledge (populated model)  Information is defined only once, linked together  Value is in the links  A change management process  Business needs define application and required infrastructure change  Project-oriented approach to EA  Projects = Change

University of California, Irvine (Administrative Computing Services) TechnoExpo, Incremental EA model development and population - ongoing  Define As-is:  Business model and processes.  Applications, data, components.  How IT systems support the business processes.  Project life cycle, SDLC  Identify desired enhancements to business as projects. For complex enhancements, organize projects into roadmaps.  Communicate, assess and track impact of change up, down, and across.

University of California, Irvine (Administrative Computing Services) TechnoExpo, Develop Change Impact Analysis Methodology  Need a change… How do you know which one, when, and how?  Analyze and articulate impact of change to business or technology.  Measure impact of moving from a current to targeted practice.  Freely available Sloan School of Management’s “Matrix of Change” tool. (

University of California, Irvine (Administrative Computing Services) TechnoExpo, Enterprise Architecture Framework  Need direction and guidance?  Many frameworks to choose from. Comparison at: doc/arch/p4/others/others.htm doc/arch/p4/others/others.htm  Adopted the Zachman Framework (  What is it?  A language that helps people think about complex concepts and communicate in non-technical terminology.  Planning tool

University of California, Irvine (Administrative Computing Services) TechnoExpo, Model and Repository Management Tool  How do I model and collect information for the EA?  Zachman Framework - powerful thinking tool  lacks technology for putting it into practice.  Storing redundant lists of “stuff” in Word, Excel, Visio was difficult.  Application lists, security information, critical business cycles  Stanford’s Protégé Knowledgebase and Ontology Tool  Auto generates forms for collecting information based on ontology and class definitions.  Generates HTML output  Open source at
