Answer: Train managers to use the appraisal process.
Step-by-step explanation:
An appraisal system is a reward system, which sets to evaluate the progress of staff, and either promote them or demote them based on their performance. It is important to consider avoiding sentiment when doing this, as it would ruin the effots of the staff and affect work flow. It is advisable that managers should stick to the appraisal methods, and avoid any form of bias that may set in, the best way would be to train managers before appraisal, and carry out a test on them, to know their sense of judgement.
