We're very excited to start bringing in modern Model-Based Systems Engineering (MBSE) approach into Flow. 

The new architecture view allows any engineer to quickly create and confirm requirements using system and behavioral diagrams, enabling faster breakdown and real-time tracking. Include more team members and make it easier for everyone to communicate by organizing information and tasks efficiently.

. To enable this new view, go over to Settings > Project > General, and enable the Systems Architecture View toggle.
