Transformational Leadership

Burns's distinction and Bass's system

In Leadership (1978), political scientist James MacGregor Burns distinguished two kinds of leader–follower relationship. Transactional leadership exchanges what each side wants, as when jobs are promised for votes; transformational leadership is a relationship in which leaders and followers raise one another to higher levels of motivation and morality. Bernard Bass (1985) carried the idea into organizations, arguing that transformational leadership leads members to work for organizational goals beyond self-interest, producing performance beyond expectations. Bass treated the two styles not as opposite poles but as dimensions that can coexist, and argued for an augmentation effect: transformational leadership adds to the effects of transactional leadership. The idea connects to Max Weber's (1922) charismatic authority and House's (1977) theory of charismatic leadership.

The four I's and the full-range model

Bass and Avolio (1994) summarized transformational leadership in four components, the four I's. Idealized influence is earning respect and trust through high ethical standards and example; inspirational motivation is communicating an appealing vision and high expectations; intellectual stimulation is questioning assumptions and encouraging creative thinking; and individualized consideration is attending to each member's needs and growth. Transactional leadership consists of contingent reward, tied to performance, and management by exception, intervening when problems arise; together with laissez-faire non-leadership these make up the full-range leadership model. The Multifactor Leadership Questionnaire (MLQ) that measures it became the most widely used leadership instrument (Antonakis et al., 2003). Shamir, House and Arthur (1993) explained that such leaders raise motivation by linking followers' self-concepts to the organization's identity.

Evidence and critiques

Meta-analyses by Lowe, Kroeck and Sivasubramaniam (1996) and by Judge and Piccolo (2004) found that transformational leadership relates consistently and positively to follower job satisfaction, satisfaction with the leader, motivation and group performance, and that contingent reward also has substantial effects. Podsakoff and colleagues (1990) reported that transformational behaviors raise organizational citizenship behavior through trust in the leader, and in a field experiment with bank managers, Barling, Weber and Kelloway (1996) reported that transformational leadership training increased follower commitment and branch financial performance. Criticism is also substantial. Yukl (1999) noted blurred boundaries between components and thin accounts of influence processes. Van Knippenberg and Sitkin (2013) argued that the concept conflates leader behavior with its effects, that measurement factor structures are unstable and that reliance on cross-sectional surveys hampers causal inference, calling for going "back to the drawing board." The debate continues in later theories such as servant leadership and authentic leadership, and in situational leadership research stressing context.

FAQ

What is transformational leadership in simple terms?

Going beyond trading rewards for results, it is leadership that changes followers' mindset through vision, example, intellectual challenge and personal attention so that they pursue larger goals on their own.

How does transformational leadership differ from transactional leadership?

Transactional leadership is an exchange of rewards and penalties for performance, while transformational leadership raises followers' values and motivation to draw effort beyond the exchange. Bass held that the two can appear together.
