Negative feedback is telling employees what they are doing incorrectly in order to improve their performance of a task.
Negative feedback describes the response from a control system that reduces the size of the stimulus, example, an elevated blood glucose concentration causes the secretion of insulin which, in turn, lowers the blood glucose concentration. Negative feedback is information that flows back to a system to reduce behavior that causes disequilibrium. In Homeostasis, Negative feedback are processes that reduce discrepancies from the set point.
