The method representation.
domain is pretty straightforward in a software design case because the process
variables for software are the real source codes. These source codes represent
each class in an object-oriented programming package. Whenever the software
designer categorizes module groups as classes using the full-design matrix, they
define the process variables for corresponded design hierarchy levels. Designers
can assume that the design matrixes for DP/PV mapping are identical to those
for FR/DP.
f. Establish interfaces by showing the relationships between objects and opera-
tions: Figure 13.9 represents the additional information for FR/DP mapping.
