If the superiors do not have a clear expectation of the subordinates, if we do not know exactly what to expect, the most likely result is nothing.Will the results of the assessment be based on the achievement of the goals? The surface sounds reasonable, but it is problematic to think carefully. If the superior only uses the goal management to decide subordinates
