An Activity-Based Methodology for Development and Analysis of Integrated DoD Architectures

A new paradigm for architecture development, Activity Based Methodology, was developed to establish a common means to express integrated architecture information consistent with intent of DoDAF, CADM and Clinger-Cohen Act. It consists of a tool-independent approach to developing fully integrated, unambiguous, and consistent DODAF views in supporting both “to-be” architecture and their gap analysis while still providing for “as-is” architectures and their analysis. The Activity Based Methodology uses a data centric approach for architecture element and product rendering instead of a product centric approach. A data centric approach supports cross-product relationships based on core set of architecture building block elements and enables several architecture objects to be automatically generated and several architecture products to be automatically rendered. The Activity Based Methodology was designed to also capture sufficient representations of “static” activity/information flow architectures models to transition them to “dynamic” executable process models for analysis of operational and system behavior over time and their related costs.
