Evolution of the Behavioral Architecture

• Start by capturing single-object, success-oriented behavior • Kernel of the system logic • For system behavior, functions and constructs are more important than inputs/outputs • Triggers between logic branches represent the minimum required I/O • Then add multi-object logic and adapt the logic structure for concurrent operation • Then add error detection and recovery logic • Keep decomposition to lower levels of detail reasonably consistent across the integrated logic • Keep decomposition of behavioral and physical architectures synchronized • Premature definition of the physical architecture (e.g., a component-first approach) reduces the ability to develop a balanced system design
