Key Takeaway

Performance appraisals involve observing and measuring an employee's performance during an appraisal period, recording these observations, communicating results to the employee, and recognizing high performance while devising ways of improving deficiencies. Most appraisals are conducted by the supervisor, but there are many advantages to using 360-degree appraisals. Appraisals that are more effective give employees adequate notice, fair hearing, and judgment based on evidence. Some companies use relative rankings in which employees are compared to each other, but this system is not suitable to all companies. A performance appraisal meeting should be planned and executed carefully, with the supervisor demonstrating empathy and supportiveness. There are intentional and unintentional biases inherent in appraisals and being aware of them, increasing rater accountability, and training managers may be useful in dealing with some of them.
