CHAPTER 3 
Software Architecture
Because of these relationships and dependencies among the elements of the 
software architecture, the practice of requirements management and traceability 
must be extended to account for the broader converge necessary to support software 
development and product sustainment. The software requirements involve the soft-
ware product, interfaces to external systems, the computational environment, and 
several post-development processes. There exists a chain of traceability from stake-
holder needs to the software product requirements, functional and physical repre-
sentations, and post-development processes that are essential to the implementation 
of the design solution. 
Figure 3.2
 depicts this requirements traceability chain for the 
software product and post-development processes. The relationships and dependen-
cies are identified and discussed in the following sections to emphasize the asso-
ciation among the architectural elements and how they coalesce into a software 
product configuration.
