System Interface Complexity: The N² Problem

Every subsystem you add to a complex system does not add one integration headache — it adds up to N-1 new ones, because every existing subsystem is a potential interface partner. This simulator renders a live 3D graph of N subsystems and lets you compare a flat, fully-meshed architecture (I = N(N-1)/2 interfaces) against a hierarchical, modular one where subsystems are grouped and each group talks to the rest of the system through a single shared bus interface. Drag the subsystem-count and module-size sliders to watch the interface graph and its live metrics — total interfaces, average interfaces per subsystem, and the percentage reduction versus the flat-mesh baseline — respond immediately, then run a verification pass to see every live interface get exercised, exactly as an integration test campaign would.
