Which appraisal method may provide insights from both internal and external sources?

The customer appraisal method is particularly valuable for providing insights from both internal and external sources. This approach involves gathering feedback and evaluations from customers, which are considered external stakeholders, as well as potentially integrating perspectives from within the organization regarding how well staff members are meeting customer needs.

By leveraging feedback directly from customers, organizations can assess how their employees are performing concerning client expectations and satisfaction, while also incorporating internal viewpoints from management or colleagues. This holistic view enables a comprehensive assessment of performance, aligning employee objectives with customer desires and market demands.

In contrast, other methods such as subordinate, team, or traditional appraisals tend to focus more on internal evaluations. Subordinate appraisals collect feedback from employees at lower levels regarding their supervisors, while team appraisals assess the performance of groups internally. Traditional appraisals are typically conducted by managers assessing the performance of their direct reports and largely overlook external feedback. Therefore, the customer appraisal method stands out by integrating both perspectives effectively.
