Which evaluation method gathers input from various sources about an employee's performance?

The 360 evaluation method is designed to collect feedback from a comprehensive array of sources, including an employee's supervisors, peers, subordinates, and sometimes even clients or customers. This approach provides a well-rounded perspective on an employee’s performance, as it incorporates diverse viewpoints and experiences.

The reason this method is especially effective is that it captures different aspects of an employee's interactions and effectiveness, resulting in a more complete assessment. Such evaluations can help identify strengths and weaknesses from multiple angles, leading to a more accurate understanding of overall performance.

In contrast, other methods, like the annual performance review, often rely heavily on a single supervisor's assessment, missing out on crucial insights from other colleagues. Peer reviews focus solely on feedback from colleagues rather than a broader view, and self-assessments rely on the employee’s personal perception of their performance, which may be biased. Therefore, the 360 evaluation stands out as the most comprehensive evaluation method by gathering input from various sources.
