Final answer:
The paired-comparison approach allows a supervisor to compare employees on a one-to-one basis during performance appraisals, potentially as part of a 360-degree evaluation process, to provide balanced feedback and facilitate discussions that can lead to learning and development.
Step-by-step explanation:
The paired-comparison approach is a method used during performance appraisals where an employee's performance can be assessed by comparing them with their peers on a one-on-one basis. This method can be particularly useful when the supervisor aims to systematically compare diverse aspects of performance and provide feedback that reflects both strengths and areas for improvement. For example, in a 360-degree performance appraisal, various sources including supervisors, colleagues, and the employees themselves contribute to evaluating an employee's performance. This can lead to comprehensive assessments that may be more balanced than those performed by a single supervisor. However, it is crucial for supervisors to be aware that different raters may have divergent perceptions, which is beneficial as it opens up opportunities for discussion and learning. The approach does not yield an absolute measure of performance but rather facilitates a more informed and rounded view of an employee's abilities and contributions.
