What is Driving and Dependence Power

The chapter explains the technique of ISM (Interpretive Structural Modeling) in Multi-criteria decision Analysis (MCDA). ISM is a method to identify inter relationship among various factors pertaining to the authors' research problem. This technique starts with identification of key factors, collected through an extensive literature review of the study. The factors are validated with the help of expert opinions. A pair wise comparative analysis helps in developing a structural self-interaction matrix (SSIM). This is followed by conversion of SSIM to Reachability Matrix, partitioned into different levels. This helps in developing a diagraph, with the help of which an ISM Model is developed. It is also accompanied by MICMAC Analysis which presents a graphical picture of the driving power and dependence power of each factor considered for the study. The chapter would help in understanding the steps involved in the application of ISM technique with the help of hypothetical cases.
