The purpose of the software architecture definition stage of development is to estab-
lish the software product functional and physical architectures, as well as initiate the 
development of the software post-development processes. The architecture defini-
tion stage is divided into two substages as depicted in 
Figure 18.1
. The first stage, 
preliminary architecture definition, is focused on decomposing top-level functions
