Dear Sejal,
The performance management system, performance appraisal system, and the evaluation of an employee's performance are highly interlinked.
For example, evaluating the performance of an employee in an organization is performance appraisal. Every company has a different system for their performance appraisal, known as the performance appraisal system, which includes the tools and techniques used for evaluating performance.
Performance appraisal system:
Performance appraisal is the process of obtaining, analyzing, and recording information about the relative worth of an employee. The focus of the performance appraisal is measuring and improving the actual performance of the employee and their future potential. Its aim is to measure what an employee does.
Performance management system:
Performance management is the process of creating a work environment or setting in which people are enabled to perform to the best of their abilities. Performance management is a whole work system that begins when a job is defined as needed and ends when an employee leaves your organization.
According to these definitions, one shall clearly understand that the performance appraisal system is a part of the performance management system. So, the short answer is that performance appraisal (annual review, employee review) fits under performance management.
Hope this gives you a small idea regarding your query.
