The Software Engineering Institute (SEI) team was involved in an Architecture-Centric Virtual Integration Process shadow project for the U.S. Army’s Aviation and Missile Research, Development, and Engineering Center (AMRDEC) Science & Technology Joint Multi-Role (JMR) vertical lift program on the Joint Common Architecture (JCA) Demonstration. The JCA Demo used the Modular Integrated Survivability (MIS) system. The MIS project provided a Situational Awareness Data Manager service that was integrated with Data Correlation and Fusion Manager (DCFM). This report summarizes the approach taken in the architecture-led safety analysis of what will be referred to as the JMR aircraft survivability situation awareness (ASSA) system. The ASSA system was the focus of the Phase 2 MIS project, in which an AMRDEC team developed support services for ASSA and contractors provided a DCFM component. These components were implemented to be in conformance with the Future Airborne Capability Environment (FACE™) Standard specification for portability and integrated on two hardware platforms. By taking an architecture-led approach to safety analysis the SEI team was been able to demonstrate the use of Architecture Analysis and Design Language and the Error Model V2 Annex standard in performing safety analysis of an embedded software system.
