ISM a computational method that involves qualitative interpretive approach solving problems based on structural mapping connections attributes their subsequent transformation into multilevel model. Using ISM, we establish seven-level hierarchy for criteria, which are then grouped four clusters driving power dependence power. result study shows can be used rank criteria help managers qualified during strategic planning phase.
