Managers lead in a wide variety of situations and organizations and have various kinds of subordinates performing diverse tasks in a multiplicity of environmental contexts. Given the wide variety of situations in which leadership occurs, what makes a manager an effective leader in one situation (such as certain traits or behaviors) is not necessarily what that manager needs to be equally effective in a different situation. Contingency models of leadership take into account the situation or context within which leadership occurs. According to contingency models, whether or not a manager is an effective leader is the result of the interplay between what the manager is like, what he or she does, and the situation in which leadership takes place.
