Answer:
There are many reason behind the failure of an appraisal system:
* Appraisal programs fail when they are not properly structured. It should be well designed because it is not a one-time process, it is required to be repeated with the passage of time more often.
* It fails when employees goals and needs are placed when setting them.
* It fails when there is lack of communication, when manager fails to communicate their expectations to the workers.
* When appraisal programs do not include recognition or rewards then chances are more that it is more likely going to fail.
