Answer:
360-degree feedback
Step-by-step explanation:
A 360-degree feedback is a full and clear communication process by which an employee receives feed-backs from customers, colleagues, supervisor, subordinates, as well as self evaluation periodically for the purpose of self improvement.
The 360 degree feedback can be used as performance appraisal tool to evaluate the performances of employees. It can also help an employee recognize one's strengths and weakness and then seek for better ways to improve.
