How Do You Know When You Are Done Decomposing and Allocating? • Decompose behavior in sufficient detail: • When a function can be uniquely allocated to a single component STOP DECOMPOSING • When a function cannot be uniquely allocated to a single component CONTINUE DECOMPOSING IT FURTHER • During the allocation/decomposition process, preserve inputs, outputs, performance, and exits (i.e., preserve behavior). • Concurrently, refine the component architecture, as required.

The objective is congruence between behavior and architecture.
