Understanding Behavior

• Shows what a system does or appears to do without regard to how (implementation) it does it • Is represented graphically by a view integrating the control (functions and constructs) view with the interface (inputs and outputs) view

Behavior is essential for providing the complete systems engineering perspective for any system or process

Why Behavioral Analysis? Why not Stop with Function Identification?

Functional analysis results in function lists/trees (necessary, not sufficient) • Incomplete sequencing of functions • Incomplete definition of items and functional interfaces • Missing performance allocation (or lacking in defensibility)

Behavioral analysis is more difficult, more time consuming, but more complete. Perform the required analysis now, or wait until integration & test to find the problems.
