Daniel, a manager at joe's fish shack, monitors the performance of workers in his department to check if the quality of their work is meeting the performance standards of the company. in doing so, which managerial task is daniel performing?

The correct answer is Controlling.

Explanation:

The control function can be defined as the phase of the administrative process that keeps the organizational activity within tolerable limits, when compared with expectations. These expectations can be set implicitly or explicitly, depending on objectives, plans, procedures or rules and regulations. Just as there is a  hierarchy of plans in a continuum of integration, there are also comparable control procedures, appropriate at different levels.

this is all on your opinion. you choose what you want to do.
