Job Performance

Job performance is a commonly used, yet poorly defined concept in industrial and organizational psychology, the branch of psychology that deals with the workplace. It's also part of Human Resources Management. It most commonly refers to whether a person performs their job well. Despite the confusion over how it should be exactly defined, performance is an extremely important criterion that relates to organizational outcomes and success. Among the most commonly accepted theories of job performance comes from the work of John P. Campbell and colleagues. Coming from a psychological perspective, Campbell describes job performance as an individual level variable. That is, performance is something a single person does. This differentiates it from more encompassing constructs such as organizational performance or national performance which are higher level variables.
