Under this method, a trained employee from personnel department interviews the line supervisor to evaluate their respective subordinates. The appraiser is fully equipped with definite test questions, usually memorised in advance, which he puts to supervisors.
The supervisor is required to give his opinion about the progress of his subordinates, the level of performance of each subordinate, his weaknesses, his good points, outstanding ability, promotability and possible plans of action in cases requiring further consideration. The appraiser takes detailed notes of the answers, which are then approved by the supervisors and placed in employee’s personal file.
