Allocating Behavior to the Physical Architecture

• Defines the collection of cooperating component parts with a common goal • Partitions the system-level conceptual behavior among the internal component parts • Moves the design • From abstract to concrete • From logical to top-level physical • Creates basis for interface design • Precipitates consideration of physical implications: • Physical limitations (e.g., weight, size, heat) • Resource constraints • Failure detection and recovery • Manufacturability • Maintainability

Partitioning System Behavior: “Trial Allocation” • Determine partitioning strategy(ies) considering • Function • Existing components • Performance • Response time

• Testing implications • Interface complexity • Technology risks • Future performance requirements • Future technologies • Associate behaviors to components • Explore many alternative partitions

• Identify resulting internal interfaces and assess complexity • (i.e., Items flow between functions associated with different components)
