What method involves gathering feedback about an employee’s performance from multiple sources?

The method that involves gathering feedback about an employee’s performance from multiple sources is known as 360-Degree Feedback. This approach is comprehensive as it collects evaluations not only from the employee’s supervisors but also from peers, subordinates, and sometimes even clients. The goal of 360-Degree Feedback is to provide a well-rounded view of an employee's performance, strengths, and areas for improvement by capturing perspectives from various stakeholders who interact with the employee in different capacities.

This method contrasts with other approaches such as peer reviews, which typically only gather feedback from colleagues, or self-assessments, where the employee evaluates their own performance, often leading to bias. Management by objectives involves setting specific measurable goals, which doesn’t provide the multi-faceted feedback aspect that 360-Degree Feedback offers. Therefore, the comprehensive nature of 360-Degree Feedback makes it a powerful tool in performance management, fostering personal and professional development by leveraging diverse viewpoints.
