Redefining architectural design and technical requirements

Unfold and iterate the following activities:

• Model the "allocated" functional architecture corresponding to the chosen physical architecture. To do this, gather the functions allocated to each subsystem and represent the sub-forms of a function scenario. As the subsystems operate roughly in parallel, the system's allocated functional architecture can be represented on a parallel structure (AND structure, or Fork/Join ). Then, using input/output/trigger flows, synchronize the functions of each subsystem that interact with the functions of the other subsystems.
