Equivalences and diffrences between SysML and Arcadia / Capella

The document is a presentation on equivalences and differences between SysML and Arcadia/Capella. It provides high-level positioning of the modeling languages and methods, outlines several diagram types that have similarities between SysML and Capella, and identifies three main differences. The presentation aims to help people understand how Capella relates to SysML while having a simpler learning curve for systems engineers.
