Step 7: Element Ranking Approval – In this step, marked as fourth and last Delphi round, a report
describing the analysis results was prepared and sent to the evaluation participants for their review. The
report contained all the elements ranking based on the final priority weights obtained from normalized
limit supermatrix. The report underscored the elements’ ranking, by indicating each alternative
performance with respect to the criterions and each criterion relative importance with respect to the goal.
Any major discrepancies between members’ weights was highlighted, and members were given a last
opportunity to revise and justify their pairwise relative judgments’, especially where notable discrepancy
exists. In this last Delphi round, two members revised some of their pairwise comparison, arguing that,
while undergoing through the evaluation process, they have become more acquainted on EI related
issues, and therefore felt the need to make adjustment to reflect their true judgments. The final element
rankings are presented in Table 3, Figure 10, Figure 11 and Figure 12.
