Structural design solution
of the technical data package is discussed later in the “Preparing the Software 
Technical Data Package” section.
The biggest challenge to software engineering is determining how to transform the 
functional architecture into the physical architecture. The functional architecture estab-
lishes the fundamental data processing tasks, data flows, logical controls, and resource 
allocations for the software design solution. The physical architecture represents the 
software structural design solution in terms of the software modules or structural units 
and how these units interact and integrate into software components. Therefore, this 
chapter discusses the following challenges to developing the physical architecture:
1. 
How are the structural units identified and specified?
