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.
