Most organizations that currently undertake Model Based System Engineering (MBSE) already have the tools required to do this. To make these processes concurrent and collaborative requires the addition of a “model-of-models” tool such as RHEA Group’s Comet / CDP4 that is currently in use at ESA.
The good news is that the Comet Community Edition is free and open-source, which significantly lowers barriers for organizations that wish to get started with Concurrent Design (CD). Similarly the models curated by the Climate Action Center Foundation are also free and open-source, thus allowing organizations to derive incredible value with very limited investment.
For organizations that have undertaken several CD activities and are becoming comfortable with concurrent / collaborative MBSE, we recommend that they explore purchasing a Comet / CDP4 Enterprise License, which offers premium support and first-in-line opportunities to submit new feature requests.
