What are the disadvantages of traditional evaluation methods? How to overcome it?

In the traditional evaluation method, managers are often evaluated by direct supervisors. Although the direct supervisor has a better understanding of subordinates (and this evaluation method can also promote the boss to pay attention to the situation and requirements of subordinates), every boss does not want to get unfavorable conclusions in the evaluation of subordinates' abilities and contributions (cultivating subordinates' abilities is often an important factor affecting the promotion of superiors), so the scores often differ too much when evaluating.

This evaluation method may also lead to managers only knowing? Only open? Bad style, only willing to seek the boss's appreciation, only doing superficial articles that the boss can see, ignoring the requirements of subordinates and relationship departments, and the work is not solid. Let relevant departments or subordinates fill in the evaluation form to overcome these shortcomings and promote managers to strengthen their sense of democracy and cooperation.
