Based on initial work for the National Maritime Domain Awareness (MDA) Enterprise Architecture, this presentation will describe an approach intended to help prioritize system descriptions within a U.S. Federal interagency information-sharing effort.
The central concept is a novel category set for the systems depicted in an enterprise architecture that highlights the highest priority messages and information exchanges. It establishes an approach for developing system services from existing authoritative data sources and system functions.
Definitions are provided for system categories for sensors; monitoring systems; collection source systems; authoritative data-system fusion nodes; discovery, analysis, and dissemination systems; first-responder systems; and responder-action systems. Similar categories can be developed for business information systems, so examples will be provided.
The resulting analysis of the system categories and the messages can be used to develop or cross-check the process and data models, as a comprehensive way of achieving consistent iterations of integrated enterprise architectures.
