How is the effectiveness of 360-degree feedback best determined?

The effectiveness of 360-degree feedback is best determined based on the range of feedback received. This approach involves collecting insights from various sources, including peers, subordinates, and supervisors, which helps provide a holistic view of an individual's performance. By gaining perspectives from multiple stakeholders, the feedback can highlight different strengths and areas for improvement that might not be visible from a single viewpoint.

A diverse range of feedback allows for a more comprehensive evaluation, enabling individuals to understand how they are perceived in different contexts and by different people. This thoroughness can contribute to more effective personal and professional development. In contrast, focusing solely on the number of respondents, limited perspectives, or an annual review does not capture the full scope of feedback necessary for meaningful development. Each of these factors may contribute somewhat, but they do not offer the depth or breadth of insight available through a wide-ranging feedback process.
