Table 2 Procedure and data Analysis.

Step 1

Identifying the Elements of Problems and Issues

• Each element of the model activity was presented to experts, who decided on the appropriateness of an aspect that should be included in the final list.

• In the final stage of the NGT, the final list was given to each expert to vote and select the appropriate activity element by ranking each element.

• A scale of 1 to 5 determines the ranking items the ISM experts choose were involved.

Step 2

Establishing the context of the relationship between variables

• The relationship of contextual phrases was determined by how the activities are to be connected.

• Contextual relations and relational phrases had been determined by expert opinion on how activities are connected.

Step 3

Develop a self-interaction structure matrix.

• ISM was developed based on the elements of activities that show the relationship between the elements.

Step 4

Generating the ISM Model

• The software generated the ISM model in pairs.

Step 5

Model Presentation

• Experts studied the generated model to check and make necessary modifications, if any.

Step 6

Presentation and Modification of Models

• The final model should be presented if any amendments were made; the next step, 7 to 9, is the analysis of the results of the final model.

Step 7

Distribution of the Reachability Matrix

• Activites were classified at different levels.

Step 8

Activity Cluster

• Activities in the model were also classified according to clusters driving power and dependence power.

Step 9

Activity Analysis and Interpretation

• Activities were analyzed and interpreted according to the importance and hierarchy of relevant activities.
