Incremental EA model development and population -

ongoingDefine 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.

Develop Change Impact Analysis Methodology

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. (http://ccs.mit.edu/MoC).

Enterprise Architecture Framework

Enterprise Architecture Framework

Need direction and guidance?Many frameworks to choose from. Comparison at:

http://www.opengroup.org/architecture/togaf8-doc/arch/p4/others/others.htm

Adopted the Zachman Framework (http://www.zifa.com)What is it?

A language that helps people think about complex concepts and communicate in non-technical terminology.

Planning tool

Model and Repository Management Tool

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 outputOpen source at http://protege.stanford.edu/

LDAP Directory Services (http://www.openldap.org)Open Source JA-SIG uPortal software. A Java-based portal

developed by Higher-Ed for Higher-Ed. (http://www.ja-sig.org)Single sign-on based on Web-ISO and Kerberos for campus-wide

web applications.

Immediate benefits - reuse of components and metrics.
