Work performance refers to the assessment and measurement of an employee's job-related activities, tasks, and responsibilities in terms of quality, quantity, efficiency, and effectiveness. It involves evaluating how well an individual meets job expectations and contributes to the overall goals and objectives of the organization.

Example
An example of a work performance evaluation would be a quarterly review conducted by a supervisor to assess an employee's ability to meet sales targets, handle customer inquiries, and adhere to company policies. This evaluation may consider factors such as the number of sales made, customer satisfaction ratings, and compliance with sales procedures.
