To implement 360 degree reviews effectively, it's essential to follow best practices. Start by clearly communicating the purpose and benefits of the review process to all participants. Use well-designed questionnaires that focus on specific, observable behaviors rather than vague attributes. Provide training for both feedback providers and recipients to ensure they understand how to give and interpret feedback constructively. Finally, use the feedback as a basis for creating actionable development plans that support the employee's growth and align with organizational goals.
