Answer: c. Both are correct
Step-by-step explanation:
Assessing the output of an employee shows some of the actual performance of that employee as it shows just how much they have contributed to the overall output of the company.
Assessing employee behavior also shows actual performance because behavior can influence output for example, how often the employee shows up to work and their work ethic when there. In the service industry as well, behavior can affect company sales as people react to how they are treated. It is therefore an important matric for actual performance evaluation.
