Answer:
The correct answer is: a 360º feedback.
Step-by-step explanation:
A 360º feedback is a common evaluation technique where not only your bosses but your peers and sometimes even the people that get your services (customers) give feedback on your general performance.
This is done to give the employee an objective and unbiased evaluation of his/her performance to analyze virtues and flaws.
In conclusion, a performance appraisal method that formally gathers input from the many people that work with, and depends on the person being appraised is called a 360º feedback.
