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.
