Final answer:
The statement is false, as the supervisor is not the only appropriate reviewer of an individual employee's performance. A 360-degree performance appraisal system involves multiple reviewers, including peers, employees supervised by the employee, and the employee themselves, to provide different perspectives and help in making improvements.
Step-by-step explanation:
b. False, The statement that due to the supervisor's authority and ultimate responsibility for performance of a unit, he is the only appropriate reviewer of an individual employee's performance is false. In a 360-degree performance appraisal system, the supervisor is just one of the many reviewers involved. This system derives ratings not only from the supervisor but also from peers, employees supervised by the employee, and even the employee themselves. The purpose of this system is to provide different perspectives of the employee's job performance and help employees make improvements through their own efforts or training.
