Transformational leadership is a style of leadership where a leader works with subordinates to identify needed change, creating a to guide the change through inspiration, and executing the change in tandem with committed members of a group. Transformational leadership serves to enhance the motivation, morale, and job performance of through a variety of mechanisms; these include connecting the follower's sense of identity and self to a project and to the collective identity of the organization; being a role model for followers in order to inspire them and to raise their interest in the project; challenging followers to take greater ownership for their work, and understanding the strengths and weaknesses of followers, allowing the leader to align followers with tasks that enhance their performance.
The concept of transformational leadership was initially introduced by James V. Downton, the first to coin the term "Transformational leadership", a concept further developed by leadership expert and presidential biographer James MacGregor Burns. According to Burns, transformational leadership can be seen when "leaders and followers make each other advance to a higher level of morality and motivation." Through the strength of their vision and personality, transformational leaders are able to inspire followers to change expectations, perceptions, and motivations to work towards common goals. Unlike in the transactional approach, it is not based on a "give and take" relationship, but on the leader's personality, traits and ability to make a change through example, articulation of an energizing vision and challenging goals. Transforming leaders are idealized in the sense that they are a moral exemplar of working towards the benefit of the team, organization and/or community. Burns theorized that transforming and transactional leadership were mutually exclusive styles. Later, researcher Bernard M. Bass expanded upon Burns' original ideas to develop what is today referred to as Bass’ Transformational Leadership Theory. According to Bass, transformational leadership can be defined based on the impact that it has on followers. Transformational leaders, Bass suggested, garner trust, respect, and admiration from their followers.
Bernard M. Bass (1985), extended the work of Burns (1978) by explaining the psychological mechanisms that underlie transforming and transactional leadership. Bass introduced the term "transformational" in place of "transforming." Bass added to the initial concepts of Burns (1978) to help explain how transformational leadership could be measured, as well as how it impacts follower motivation and performance. The extent to which a leader is transformational, is measured first, in terms of his influence on the followers. The followers of such a leader feel trust, admiration, loyalty and respect for the leader and because of the qualities of the transformational leader are willing to work harder than originally expected. These outcomes occur because the transformational leader offers followers something more than just working for self-gain; they provide followers with an inspiring mission and vision and give them an identity. The leader transforms and motivates followers through his or her idealized influence (earlier referred to as charisma), intellectual stimulation and individual consideration. In addition, this leader encourages followers to come up with new and unique ways to challenge the status quo and to alter the environment to support being successful. Finally, in contrast to Burns, Bass suggested that leadership can simultaneously display both transformational and transactional leadership.
