As HRM on your first visit to branch you found some personal files do not contain 6 month appraisal review within the last 12 month, what's your comment?

First you have to consider the company's policies regarding the appraisal process. Find the person accountable for the appraisal process and figure out the underlying reason for it. It might have been due to the negligence of duties, irresponsibility, or in certain rare cases, mistakenly. Find a quick solution and implement certain procedures so that it can be avoided in future.
