Chapter 10: Formulating the Functional Architecture.
 This chapter discusses 
the nature of the functional architecture and how it is developed by decompos-
ing specified requirements into successive layers of functional elements. Each 
functional element is specified in an approach of continual refinement that cul-
minates when a function is recognized to be uncomplicated and for which an 
implementation can be realized. The functional architecture provides a logical 
and coherent representation of the software product’s behavior in response to 
stimulus, events, or conditions that arise within the computing environment.
