Potential System Integration Issues in the Joint Multi-Role (JMR) Joint Common Architecture (JCA) Demonstration System

Report Date:



The Carnegie Mellon University Software Engineering Institute (SEI) was involved in an Architecture-Centric Virtual Integration Process (ACVIP) shadow project for the U.S. Armys Research, Development, and Engineering Command Joint Multi-Role vertical lift program in the Joint Common Architecture (JCA) Demonstration. The JCA Demo used the Modular Integrated Survivability (MIS) system, which provided a situational awareness service that will be integrated with two instances of a Data Correlation and Fusion Manager (DCFM) software component, which was contracted to two suppliers. The purpose of the ACVIP shadow project was to demonstrate the value of using ACVIP technology, in particular the architecture models expressed in the Society of Automotive Engineering Aerospace Standard 5506 for the Architecture Analysis and Design Language (AADL), for discovering potential system integration problems early in the development process. To do this, the SEI first captured information from existing requirements documents and other documentation in AADL.Then, by taking an architecture-led approach to specifying requirements, the SEI quickly identified a number of issues that, if not addressed, would result in system integration problems between MIS and DCFM. The SEIs findings gave the MIS and DCFM contractor teams the opportunity to discuss these issues in program meetings early in system development.
