  • Enterprise Information Architecture for Traceability Ben K Bovée Principal, Patterndigm, Fairfax, Virginia, USAbstract - The value of any Enterprise Information documents referenced, and abbreviations for lengthy terms–Architecture (EIA) is assessable in terms of its utilization to especially those repeated.enable change management throughout the SystemDevelopment Life Cycle (SDLC). The presented framework 1.1 Situationdepicts generic concerns at the intersection of natural humanthought processes and business perspectives; features The ZF has axes and contents which yield more basic anddifferentiating it from other EIA frameworks are: exploratory research findings than applied and confirmatory research results facilitating business and system development • Enabling comprehensive traceability for any organization and management. The ZF perspective axis identifies five roles endeavor to effect change management; (planner, owner, architect, designer and builder) which is an incomplete set of roles of ambiguously related to real-world • Leveraging natural human thought processes patterns in roles. Each of the aforementioned roles is associated with a any SDLC; ZF row. Each of the “five Ws” is associated with a ZF column. • Basing business perspectives on National Institutes of Standards and Technology (NIST) perspectives; The ZF, while a noble attempt to holistically characterize enterprise information, is an over-simplification and falls short • Augmenting NIST perspectives with in the ability to comprehensively and consistently effect analytical/architectural perspective; and information traceability supporting all enterprise perspectives. • “Five Ws” concerns are at intersections of 1.2 Problem aforementioned subjects and perspectives (instead of The ZF assumes the “five Ws” are consistent for all enterprise assuming concerns are identical from different perspectives, but they are not.

Perhapsthe most noble attempt to analyze the Zachman Framework([4]), is not able to explain: • Columns one or two (all) rows other than discussing data and manual process modeling; • Column three rows one, four or five; • Column four rows one, four or five; • Column five rows four or five; and • Column six rows one, four or five.
