What is employee performance according to different scholars?

Employee performance is defined variably by scholars across disciplines. Some view it as the achievement of specific job-related tasks and goals, focusing on productivity and efficiency (Campbell, 1990). Others emphasize behavioral aspects, highlighting the importance of interpersonal skills and teamwork (Borman & Motowidlo, 1993). Additionally, some researchers incorporate factors such as motivation and engagement, suggesting that performance encompasses both outcomes and the processes leading to them (Schmitt, 2004).
