Evolution of Leadership Theories: From the "Great Man" to a Systems Perspective

Why Leadership Is More Important Than Management

Peter Drucker: "Management is about doing things right; leadership is about doing the right things." Management manages complexity; leadership manages change. In a stable environment, good management suffices; in an era of transformation, an organization perishes without leadership.

The "Great Man" Theory and Leader Traits

Early theories (19th – early 20th century) were based on the innate qualities of leaders. "Great leaders are born, not made." Researchers sought universal traits: intelligence, confidence, dominance, charisma.

Limitations: there is no single set of traits that predicts leader success; context changes the requirements; the theory ignores followers.

Behavioral Theories

1940–60s: shift from "who is the leader" to "what does the leader do." Two key axes of behavior:

Task orientation (initiating structure): planning, organizing, instructions, control. "Are we getting things done?"

Relationship orientation (consideration): support, trust, respect, attention to people's needs. "How are the people feeling?"

Studies showed: the most effective leaders are high on both parameters simultaneously.

Situational Theories

The best style depends on the situation. Hersey and Blanchard’s model (situational leadership): the style is chosen depending on the "maturity" of the followers.

• S1 (Directing): high task orientation, low relationship orientation → for beginners (M1: low competence, high motivation)
• S2 (Coaching): high task + high relationship → for discouraged novices (M2)
• S3 (Supporting): low task + high relationship → for competent but insecure (M3)
• S4 (Delegating): low task + low relationship → for competent and motivated (M4)

Transformational vs Transactional Leadership

Transactional leadership: exchange — you do X, I give Y. Understandable, predictable, effective in a stable environment. Tools: KPIs, bonuses, penalties.

Transformational leadership (Burns, Bass): the leader inspires followers, transforming their values and motivation. The 4 "Is": Idealised Influence (charisma), Inspirational Motivation, Intellectual Stimulation, Individualised Consideration.

Studies confirm: transformational leaders achieve higher organizational performance, especially during change.

Practical Assignment

Choose a leader whom you consider outstanding (from business, politics, history). Evaluate their style according to each theory: (1) Which leader traits does he or she embody? (2) How does their style change depending on the situation? (3) Transformational or transactional? Provide specific examples.
