Answer:
a. Measuring actual performance
Step-by-step explanation:
The department receives the performance report which summarizes the actual performance, but as the report does not include the rejected rates that means the department shall be considering the rates also.
The department shall consider the measuring of actual performance by themselves also.
This shall not be left up on the statistics received. Rather if the calculations are done previously, it shall be a reconciliation between the own report and that of the statistics.
This shall help them to improve their performance.
