In terms of academic roots, the field that really has taken the lead in theorizing about the organization of purposeful human behavior is sociology. … - Steve M. Jex

Job performance is a deceptively simple term. At the most general level, it can be defined simply as “all of the behaviors employees engage in while at work.” Unfortunately, this is a rather imprecise definition because employees often engage in behaviors at work that have little or nothing to do with job-specific tasks.

Organizational constraints represent situations or things that prevent employees from translating ability and effort into high levels of job performance. The [Organizational Constraints Scale] OCS was based on the work of Peters and O'Connor (1980), who listed 11 areas of constraints that interfered with job performance. These common situational constraints in organizations may include faulty equipment, incomplete or poor information, or perhaps interruptions by others.

In the organizational sciences (e.g., organizational behavior, organizational psychology), one of the more misunderstood terms is “organizational theory.” To some, organizational theory is a field of study; to others, it is the process of using metaphors to describe organizational processes... or it represents an attempt to determine the best way to organize work organizations. The term is used to indicate all of these things, but an “organizational theory” is really just a way of organizing purposeful human action. Given the diversity of purposeful human endeavors, there are numerous ways to organize them, and, hence, a great many organizational theories.
