3.3 Step-3 ISM Approach
Sage [37], in 1977, defined Interpretive Structure Modeling (ISM) as an approach that imposes order and direction on the complicated element and system relationships to create a holistic model. This is a dynamic method of learning that allows us to put together a comprehensive representation of the topic by connecting its many parts. The model uses clear patterns to show the structure’s complexity through graphs and words [38]. The ISM approach assists in finding various relationships in complicated situations when the relationship consists of different variables [39, 40]. Several scholars have used this method to construct a better conceptual framework for the system under examination [41-45]. Figure 2 explains the steps taken by the ISM methodology to determine the connection between RE security practices categorization.
