3.2 Application of CDMod (Instantiation)
With CDMod it is possible to identify qualities and drawbacks of
the compared models. The first step for the application of CDM is
to establish two SDM's (Software Design Methods) to be
compared; in our case we will select two Software Development
Models - SDMod.
3.2.1 Construction of the Process Model
The first step is to build the Process Model, which identify the
components of the models. At this point the components are
extracted in a high level of abstraction, with no evaluation of
comparable components. The main extracted components of the
Waterfall Model [7] are presented in Table 1. The Spiral Model is
composed of four different Stages; the main extracted components
of the Spiral Model are presented in the Table 2. A formalism is
used to classify the components and build the process model. The
SLANG formalism for the Waterfall and Spiral models are shown
in the Figure 4 and Figure 5.
