Leadership is one of the most salient aspects of the organizational context.However,defining leadership has been challenging.The following sections discuss several important aspects of leadership including a description of what leadership is and a description of several popular theories and styles of leadership.This page also dives into topics such as the role of emotions and vision,as well leadership effectiveness and performance.Finally,this page discusses leadership in different contexts,how it may differ from related concepts (i.e.,management),and some critiques that have been raised about leadership.
Leadership has been described as the “process of social influence in which one person is able to enlist the aid and support of others in the accomplishment of a common task” [1].A definition more inclusive of followers comes from Alan Keith of Genentech who said "Leadership is ultimately about creating a way for people to contribute to making something extraordinary happen." [2] Students of leadership have produced theories involving traits [3],situational interaction,function,behavior,power,vision and values [4],charisma,and intelligence among others
Functional leadership theory (Hackman & Walton,1986; McGrath,1962) is a particularly useful theory for addressing specific leader behaviors expected to contribute to organizational or unit effectiveness.This theory argues that the leader’s main job is to see that whatever is necessary to group needs is taken care of; thus,a leader can be said to have done their job well when they have contributed to group effectiveness and cohesion (Fleishman et al.,1991; Hackman & Wageman,2005; Hackman & Walton,1986).While functional leadership theory has most often been applied to team leadership (Zaccaro,Rittman,& Marks,2001),it has also been effectively applied to broader organizational leadership as well (Zaccaro,2001).In summarizing literature on functional leadership (see Kozlowski et al.(1996),Zaccaro et al.(2001),Hackman and Walton (1986),Hackman & Wageman (2005),Morgeson (2005)),Klein,Zeigert,Knight,and Xiao (2006) observed five broad functions a leader provides when promoting unit effectiveness.These functions include:(1) environmental monitoring,(2) organizing subordinate activities,(3) teaching and coaching subordinates,(4) motivating others,and (5) intervening actively in the group’s work.
A variety of leadership behaviors are expected to facilitate these functions.In initial work identifying leader behavior,Fleishman (Fleishman,1953) observed that subordinates perceived their supervisors’ behavior in terms of two broad categories referred to as consideration and initiating structure.Consideration includes behavior involved in fostering effective relationships.Examples of such behavior would include showing concern for a subordinate or acting in a supportive manner towards others.Initiating structure involves the actions of the leader focused specifically on task accomplishment.This could include role clarification,setting performance standards,and holding subordinates accountable to those standards.
