The group and exchange theories of leadership are derived from social psychology. These have their roots in the exchange theory. Leaders from different kinds of relationships with various groups of subordinates. Group theories describe how leaders need to maintain their position in group dynamics.
Social exchange theory proposes that social behavior is the result of an exchange process. The purpose of this exchange is to maximize benefits and minimize costs. Social Exchange Theory is a social psychological and sociological perspective that explains social change and stability as a process of negotiated exchanges between parties. Social Exchange Theory posits that all human relationships are formed by the use of a subjective cost-benefit analysis and the comparison of alternatives.
Costs are the elements of relational life that have negative value to a person, like time, money, effort etc. and on the other hand rewards are the elements of a relationship that have positive value like sense of acceptance, support, and companionship etc. The Social Exchange perspective argues that people calculate the overall worth of a particular relationship by subtracting its costs from the rewards it provides. If worth is a positive number, it is positive relationship. On the contrary, negative number indicates a negative relationship. The worth of a relationship influences its outcome, or whether people will continue with a relationship or terminate it. Positive relationships are expected to endure, whereas negative relationships will probably terminate.
Social exchange theory can also be applied to leadership studies as reported by Hollandder and Julian (1969). They propose that the leader provides more benefits or regards than burden or costs to the followers who in exchange help him achieve the goals of the organization. There must be a positive exchange between the leader and followers in order for group goals to be accomplished. According to this group of theories, a leader provides more benefits/rewards than burdens/costs for followers.
In a group, members make contributions at a cost to themselves and receive benefits at a cost to the group or other members. The leader can give rewards to his followers in the form of appreciation or monetary increments or promotion for accomplishment of the organizational goals or tasks. These rewards have positive impact on attitudes, satisfaction and performance of the followers.
In return of these awards, followers respect the leader and give him due regard for his status and esteem and believe in his heightened influence. The leader tends to follow initiating structure when followers do not perform very well and increases his emphasis on consideration when the followers do a good job.
In this balancing act, the perception of his followers of his being an effective leader increases and this equation is mutually beneficial for both the leader and the follower. Interaction continues because members find the social exchange mutually rewarding.
Role theory is a concept in sociology and the role theory of leadership borrows these concepts to explain how people adapt to specific organizational and leadership roles. How the leaders and followers in an organizational context define their own roles, define the roles of others, how people act in their roles and how people expect people to act in their roles within the organization.
Leadership Participation Inventory (LPI)
Kouzes and Posner introduced the Leadership Participation Inventory model of Transformational leadership. This model is also known as Kouzes and Posner's Leadership Challenge Model. They identified five practices of exemplary leadership - Model the Way, Inspire a Shared Vision, Challenge the Process, Enabling Others to Act, and Encourage the Heart.
The Hersey and Blanchard Situational Theory model suggests that a leader must adapt his leadership style based on task and relationship behaviors appropriate to the situation. Leadership style is dependent on the maturity level and abilities of followers. Under this model, successful leadership is both task-relevant and relationship-relevant.
Contingency Theories in Action
Contingency theory suggests matching the best leader to a specific situation based on situational factors and the leadership style. The practical application of theory can be done in various ways. The workplace example is to determine the best candidate for a given set of requirements using the LPC score. Applying the model to determine a leader's ability to adapt in the scenario of a new project etc..
Lewin’s Change Management Model
Lewin's change management model is a framework for managing organizational change. Lewin's methodology of different Leadership Styles recognizes three distinct stages of change - creating the perception; moving toward the new desired level of behavior and, ensuring new behavior as the norm.
Charismatic leadership is a trait-based leadership theory where the leaders act as visionary driven by their convictions and motivate their followers to work towards common vision using their charm and persuasiveness. These charismatic leaders act as role models and exhibit extraordinary characteristics that inspire devotion and motivation in followers to persuade change. Leaders are able to cultivate a profound sense of trust with the group of followers.
Investment Theory of Creativity
Sternberg in the year 2006, proposed the investment and confluence theory focused on understanding creativity. According to the investment theory, creativity requires a confluence of six distinct but interrelated resources known as intellectual abilities, knowledge, styles of thinking, personality, motivation, and environment. It emphasizes that creativity is not about one thing, but about a system of things.
Situational Theories of Leadership
The situational theories of leadership assume that the most effective style of leadership depends from situation to situation. Situational leadership is a leadership style in which the leader must adjust to match the development needs of the followers. They must adapt varying behaviors to strike the right balance between task & relationship based on different levels of maturity of followers and also as followers develop and cultivate their skills.
The skills approach to leadership suggests that certain skills are important for effective leadership. Skills are what leaders can learn and develop, whereas traits are innate characteristics. The main skills needed for leadership, according to one such theory, are technical, human, and conceptual.
McClelland's Theory of Needs is a human motivation theory which states that an individual's specific needs are acquired over time through our culture and life experiences. As per the three needs theory, these acquired needs significantly influence the behavior of an individual. The three main driving motivators are the needs for achievement, affiliation, and power.
