4.3.4 Interpretation of ISM Model
The final version of the ISM model was developed based on the results of
the reachability matrix. The interconnections between the criteria are
illustrated by arrows that point from one criterion to another. After
the digraph was successfully converted to the ISM model, the
transitivity analysis was carried out to determine whether or not the
data contained any ambiguity (see Figure 3). In this figure RE1
”Awareness of SRE” category stands on the top for selecting RE practices
for GSD organizations in the context of SSD. This shows that RE1 is an
independent category in the identified list of RE practices for GSD
organizations. All the other categories are dependent on RE1.
