# Evaluating and Ranking SCPMS Enablers Using ISM and SWARA
## 4 Results
### Phase 2  
The ISM and MICMAC processes were well defined in the previous section and are available in the literature. The ISM and MICMAC steps are systematically followed to derive a series of matrices. The fundamental matrix (i.e., SSIM) is formed using expert feedback. The contextual relationship among the variables plays a significant role in ISM and MICMAC. The SSIM is often created utilizing input from a group of experts. In terms of standard rules, the contextual link between SCPMS enablers is expressed. The different standard rules used in expressing contextual relationships are discussed in the research methodology. One such relationship may be interpreted; for example, E1 'leagility', was compared with E7 'C 4.0 performance measurement awareness' to derive the contextual relationship. It was found that E1 is influenced by E7; hence, the contextual relationship shows 'A' which indicates that E1 is influenced by E7. Similarly, all the contextual relationships were transformed using 'V', 'A', 'X', and 'O' to form the SSIM according to Table 3. \begin{table}

Table 2: Supply chain enablers and references. It is possible to convert SSIM into an initial reachability matrix (IRM). By substituting binary digits for the conventional code and following the guidelines outlined in the previous section, IRM may be produced. The transformed matrix using 0 and 1 is displayed in Table 4.
