COMPASS tool vision for a system of systems Collaborative Development Environment

It would be useful to have a tool platform that supports systematic engineering of Systems of Systems, especially focused on the case where multiple parties are collaborating on the development. We attempt to provide a vision for a tool that allows collaboration on models developed jointly and that can be systematically analysed. The focus is on the challenges that make this kind of tool - a Collaborative Development Environment- different from a traditional Integrated Development Environment. Finally the paper describes the plans of the COMPASS project to address these challenges.
