Phase 3 of the Model-Based Systems Engineering (MBSE) interoperability project evaluates the business context and tool alternatives for exchanging requirements and architecture representations depicting systems and system components. It attempts to identify the minimum content that must be exchanged based on popular authoring technologies. The project distinguishes the use cases that describe the exchange scenarios and the most appropriate technical data needed for interoperability. A mapping between two major modelling languages, SysML and ARCADIA, is defined for each use case. The outcome was a scoring of capabilities needed to implement a full-scale solution across a multi-tier supply chain. The project was based on the following problem statement and objective.

The intent of this document is to convey the current state of data interoperability in the industry, to identify an interim solution, and to influence future solutions and best practices for MBSE model interchange that enable model-based collaboration across the A&D supply chain. This position paper reviews the various alternatives considered by the group and makes initial recommendations on the most promising approaches to enable OEM–supply chain design collaboration based on both short- and long-term MBSE standards.
