The core idea of the Jev model is that a shared system's behavior is governed by how close demand sits to capacity, not by demand alone. Picture a single dial: at the calm end, spare capacity absorbs variation and waits stay short; as the dial turns toward the limit, waits stretch sharply; past the limit, a backlog accumulates without settling. The same demand produces completely different behavior depending on where the dial sits, which is exactly what a single average cannot show.

A single average told us the line was fine. But the line was not fine — it was one small push away from never recovering. So instead of asking how much demand there is, the Jev model asks a different question: how close is demand sitting to capacity?
