11.4.4 
Assess optimization opportunities
The functional architecture must be assessed to identify opportunities for improve-
ment. The cost of optimizing the functional design (decomposition and behav-
iors) must be justified by a significant gain in performance or reduction in design 
complexity.
11.5 
Establish the functional architecture
The functional architecture should be placed under technical configuration con-
trol to establish a functional design baseline for software design synthesis. The

11.5 
Establish the functional architecture
functional architecture must be complete and traceable to software specifications. 
The software engineering team representatives from software implementation and 
test and evaluation organizations must endorse the functional architecture and 
revise their technical plans and schedules to align organizational resources with 
anticipated task assignments.
The functional architecture must be documented to provide the diagrams, draw-
ings, models, and specifications against which software design synthesis can be 
performed and evaluated. Functional architecture includes the design documenta-
tion shown in
