Work performance refers to how effectively an individual completes their job tasks and responsibilities. It is often evaluated based on factors such as productivity, quality of work, and adherence to deadlines. Employers may assess work performance through regular reviews, feedback, and performance metrics. Improving work performance can involve setting clear goals, enhancing skills through training, and fostering a positive work environment. Tools like performance appraisals and key performance indicators (KPIs) are commonly used to measure and track progress, helping both employees and managers identify areas for growth and development.
