◤ ◤ DEFINITION
What it is
L2 decomposes L1 onto subsystems. Each L2 specifies the behavior, interfaces, and performance one subsystem must deliver so that the union of subsystems satisfies the parent L1.
◤ ◤ PURPOSE
Why it exists
Allocates work and budgets across teams, locks subsystem interfaces, and produces the layer at which most ICDs are written.
