## 2 Literature Review
### Literature Review for TISM-MICMAC Approach  
In this section, the TISM-MICMAC methodology is identified for different scenarios from the literature to determine the interrelationship between the enablers, hierarchies, and critical enablers. A summary of the TISM-MICMAC methodology for different problems is presented in Table 3.
