1.6 Leadership Theories and the Role of Leaders in Strategy

Executive Summary: Crafting and implementing strategy to turn a vision into reality is a core leadership function. This section traces how leadership theory developed—from traits, to behaviours such as those in Blake and Mouton's grid, to contingency models—and then sets out what leaders actually do across the strategy process. Transactional, transformational and situational leadership are developed further in Section 13.5.

What Is Leadership?

Leadership is the process of influencing people to work willingly toward shared goals. It differs from management, which brings order and predictability through planning, budgeting, organising and controlling. John Kotter's distinction—management copes with complexity, leadership copes with change—is examined in Section 13.5. Organisations need both: strong management without leadership becomes bureaucratic, and leadership without management becomes chaotic.

Leadership is not confined to the chief executive. Board chairs, executives, middle managers and project leaders all exercise leadership, and modern organisations increasingly rely on shared or distributed leadership across teams.

How Leadership Theory Developed

Trait theories

Early research looked for traits that distinguish leaders: intelligence, self-confidence, determination, integrity and sociability. Reviews such as Ralph Stogdill's found that traits matter but do not guarantee effective leadership, because what works depends on the followers and the situation. Traits are therefore a starting point rather than a full explanation.

Behavioural theories

Researchers then studied what effective leaders do. The Ohio State studies identified two behaviours—initiating structure (organising tasks and setting standards) and consideration (showing concern for people). Kurt Lewin contrasted autocratic, democratic and laissez-faire styles.

Robert Blake and Jane Mouton's Managerial (Leadership) Grid plots concern for production (horizontal axis) against concern for people (vertical axis), each on a scale of 1 to 9:

Blake and Mouton argued that 9,9 team management is the most effective in most situations. In case questions, classify a leader by evidence: a CEO who holds open coffee sessions and puts culture first but avoids hard performance conversations leans toward 1,9; one who demands detailed reports and controls every decision leans toward 9,1.

Contingency theories

Contingency theories hold that the best style depends on the situation:

• Fiedler's contingency model measures whether a leader is task- or relationship-oriented and rates the situation on leader–member relations, task structure and position power. Task-oriented leaders do best when the situation is very favourable or very unfavourable; relationship-oriented leaders do best in moderately favourable situations.
• Path–goal theory (Robert House) says leaders should choose directive, supportive, participative or achievement-oriented behaviour to clear the path to followers' goals.
• Situational leadership (Hersey and Blanchard) matches directing, coaching, supporting or delegating to follower readiness (Section 13.5).

Contemporary perspectives

Later theories emphasise the relationship between leaders and followers: transformational leadership (inspiring change through vision and individual development), servant leadership (Robert Greenleaf's idea that leaders serve the growth of their people), and authentic and ethical leadership. Jim Collins's research on companies that made a lasting step-change in performance described Level 5 leaders, who combine personal humility with intense professional will.

The Role of Leaders in Strategy

Strategic leaders shape the organisation's direction and its capacity to deliver. Their roles span the strategy process:

1. Setting direction: articulating purpose, vision and values, and deciding where the organisation will compete.
2. Making strategic choices: deciding which options to pursue and, just as important, which not to pursue.
3. Aligning the organisation: ensuring structure, systems, resources and incentives support the strategy.
4. Building capabilities and culture: developing people and the routines that become sources of advantage.
5. Leading change and making sense of it: explaining why change is needed, interpreting ambiguous signals and keeping people committed through uncertainty.
6. Setting the ethical tone: modelling the values and holding others to them.

Strategic thinking (creative, synthesising and future-focused) and strategic planning (analytical and programmatic) complement each other; leaders need to balance them. Middle managers play a crucial linking role: they translate strategy into operational plans, relay frontline information upward and often originate emergent strategies.

Applying Leadership Theory to Case Questions

When a case describes a leader, first classify the style with evidence (for example, a grid position or a contingency fit), then judge whether that style suits the situation and the strategy. A turnaround with an urgent cash crisis may justify a more directive, task-focused style for a period; a strategy that depends on innovation needs leaders who invite challenge and develop people. Finish by recommending specific behaviours—such as clearer performance conversations, more delegation or more visible communication of the vision—rather than simply naming a theory.
