For a single factor, the projects have the best overall control. However, this does not necessarily mean every control is the best. Consider X2 as an example, where P1, P2, P3, and P4 are calculated as 83.4, 80.7, 80.8, and 84.9, respectively. The results show that although P1 has the highest performance, X2 control must be optimized for enhanced results. Although P4 has effective control in X2, it has insufficient control and management over human factors, which results in a low management level.
