CIOs Feel...Overwhelmed?Ill-equipped?

Behind the market?Over-sold?

At risk?

• No body of knowledge from which to leverage lessons learned

• No evaluation techniques to assess COTS solutions interoperability or usability

• No architecture modeling tools for assessing risks or composability

• No formalisms (lexicons) to describe component feature interactions and dependencies

• No formal XML DTDs to represent architecture “blueprints”

Best Practices

A Normalized Solution A Normalized Solution Framework;Framework;

Provide a formal methodology, collaboration tools and information for transformation of business drivers into proven and interoperable solution sets

Propagate a knowledge base of EA artifacts

Provide means of sharing best practices and lessons learned

Increase the integrity, timeliness, and contextual relevance of architecture communications between buyers and suppliers

Solution Framework Objectives

•Reduce uncertainty and risk of mapping solutions to common business requirements

•Improve visibility of key technical features, interfaces, functions

•Provide consistent approach for evolving solution paradigms for COTS product usage

•Generate Industry approval and consensus•Facilitate compliance with Clinger-Cohen, FAROMB Circulars A119 & A130, S.803, FEAPMO

•Provide “clearinghouse” of reusable artifacts and supporting research

“The ICH repository data and analysis methodologies was very helpful in supporting a quick turn around for [Information Assurance] section of COTS security products. Highly detailed ICH technology domain and product evaluation data comprised over 60% of this urgently needed [architecture] report”. Mike Luby, Program Manager, Logicon/PRC
