Leadership theory has generated more scholarly output and more popular management writing than almost any other management topic — and the resulting landscape is simultaneously rich with insights and cluttered with contradictions, fads, and overextended claims. DB8610 navigates this landscape with doctoral rigor: examining the major theoretical traditions, evaluating the evidence for their claims, identifying where different frameworks converge and diverge, and developing the scholarly perspective on leadership that a DBA specialization in leadership requires.
Major leadership theory traditions
From trait theories to contemporary frameworks
- Trait and behavioral theories: DB8610 examines the historical development of leadership theory from trait approaches (the belief that effective leaders possess distinctive personal characteristics that can be identified and selected for — the "great man" tradition) through behavioral approaches (the shift from who leaders are to what leaders do, culminating in the Ohio State and Michigan studies that identified initiating structure/task orientation and consideration/relationship orientation as the primary dimensions of leader behavior). The trait tradition was partially rehabilitated by meta-analytic research showing that certain traits — intelligence, conscientiousness, openness to experience, extraversion, and emotional stability — do predict leadership emergence and effectiveness, though with significant contextual moderation
- Contingency and situational theories: The course examines the contingency revolution in leadership theory — the insight that effective leader behavior depends on contextual factors that moderate which leadership approach produces best outcomes. Fiedler's contingency model (1967) matched leader style [task-oriented vs. relationship-oriented] to situational favorableness [determined by leader-member relations, task structure, and position power]. Hersey and Blanchard's Situational Leadership model (1969, revised 1977) matched leadership style [directing, coaching, supporting, delegating] to follower development level [competence and commitment]. Path-goal theory (House, 1971; Evans, 1970) specified how leader behavior [directive, supportive, participative, achievement-oriented] should be selected based on follower and environmental characteristics to maximize follower motivation and performance. The empirical evidence for specific contingency predictions is mixed, but the core insight — that effective leadership requires diagnosing situational demands and adapting behavior accordingly — has proven durable
- Transformational and transactional leadership: Burns's (1978) distinction between transformational leadership (appealing to followers' higher-order values and motivating them to transcend self-interest for a collective vision) and transactional leadership (exchange-based influence through contingent reward and management by exception) initiated one of the most productive research programs in leadership scholarship. Bass and Avolio's (1993) Full Range Leadership model operationalized these constructs in the Multifactor Leadership Questionnaire (MLQ) and generated hundreds of studies. Meta-analyses consistently show positive relationships between transformational leadership and follower performance, satisfaction, and organizational effectiveness — but also show that transactional leadership (particularly contingent reward) contributes independently to follower performance, suggesting that the most effective leaders exhibit both transformational and transactional behaviors rather than relying exclusively on transformational approaches
Authentic, servant, and ethical leadership
DB8610 examines the contemporary leadership frameworks that have emerged partly in response to high-profile corporate scandals and the demand for leadership that prioritizes ethics and follower development alongside performance. Authentic leadership theory (Luthans & Avolio, 2003; Walumbwa et al., 2008) proposes that effective leaders exhibit self-awareness (knowing their values, emotions, and goals), relational transparency (openly sharing their values and thoughts), balanced processing (objectively analyzing information before deciding), and internalized moral perspective (making decisions based on internalized ethical values rather than external pressure). The empirical evidence on authentic leadership's distinctive contribution (beyond transformational leadership) is promising but still developing. Servant leadership (Greenleaf, 1977; Spears, 1995; van Dierendonck, 2011) proposes that the primary purpose of leadership is serving followers — helping them develop, perform, and flourish — with organizational effectiveness as an outcome of follower development rather than an end in itself. Ethical leadership (Brown, Treviño, & Harrison, 2005) focuses specifically on leaders' role in shaping the ethical climate of their organizations: through their personal ethical conduct, through explicit communication about ethical standards, and through the use of reward systems to reinforce ethical behavior. The course examines how these contemporary leadership frameworks complement and extend the transformational leadership tradition, and what the available evidence suggests about their distinctive contributions to follower and organizational outcomes.
Creative thinking and innovation in leadership
DB8610 examines creative thinking as a leadership competency — the capacity to approach problems with fresh perspectives, generate novel solutions, and create organizational conditions that enable creativity and innovation in others. The course examines the cognitive science of creativity: divergent thinking (fluency, flexibility, originality, and elaboration — Guilford's original creativity dimensions); convergent thinking (the evaluation and selection process that determines which divergent ideas are worth pursuing); creative problem solving models (Osborn-Parnes Creative Problem Solving process; Design Thinking's empathize-define-ideate-prototype-test cycle; SCAMPER — Substitute, Combine, Adapt, Modify, Put to other uses, Eliminate, Reverse); and the organizational factors that facilitate or inhibit creative performance (intrinsic motivation, creative self-efficacy, resource availability, supervisory encouragement, organizational climate for creativity — Amabile's componential model of creativity). The course also examines the leadership behaviors that research associates with subordinate creativity: supporting creative self-efficacy, buffering creative employees from bureaucratic constraints, providing autonomy while maintaining direction, recognizing and rewarding creative contributions, and modeling creative risk-taking in the leader's own behavior.
Gap analysis and leadership project development
DB8610 applies leadership theory to the identification and analysis of leadership practice gaps — the starting point for the DBA capstone projects in the leadership specialization. The course develops gap analysis methodology in the leadership context: using survey instruments, observation protocols, and secondary performance data to characterize the current state of leadership practice in an organizational context; using the leadership theory literature to define the desired state of leadership practice (what does transformational leadership look like in this specific organizational context? what would servant leadership practices produce for employees in this organization? what does the evidence suggest about which leadership practices most strongly predict performance in this industry and function?); identifying the gap between current and desired state with sufficient specificity to develop a focused investigation; and developing preliminary project concepts for the DBA capstone — the applied leadership investigation that will form the culminating deliverable of the leadership specialization.

Frequently asked questions
DB8610 develops a nuanced, evidence-based answer to this question — one that resists the popular tendency to declare a single "best" leadership approach while also avoiding the unhelpful conclusion that "it all depends." The meta-analytic evidence (which aggregates findings across dozens or hundreds of primary studies) provides the most reliable basis for answering this question. The most consistent finding across decades of leadership research is that transformational leadership — particularly the idealized influence (role modeling), inspirational motivation, intellectual stimulation, and individualized consideration dimensions of the Full Range Leadership model — is positively associated with follower performance, satisfaction, commitment, and organizational effectiveness across a wide range of organizational contexts, cultures, and industries. Transformational leadership's effect sizes are among the largest and most consistent in leadership research. Transactional contingent reward — providing clear expectations and recognizing performance that meets those expectations — also consistently predicts follower performance and adds incrementally to transformational leadership rather than substituting for it. The research does show meaningful contextual moderation: transformational leadership's effects are stronger in contexts of high uncertainty and change (where followers are more responsive to vision and inspiration); leader-member exchange quality (the relational quality between specific leaders and specific followers) moderates the effects of leader behavior on follower outcomes (high-quality LMX amplifies the effects of supportive leader behavior); and national culture moderates which specific leadership dimensions are most effective (power distance and collectivism moderate preferences for participative vs. directive leadership, though the evidence suggests transformational leadership is effective across most cultural contexts). The honest bottom line: no single leadership style is universally superior across all situations, but the evidence is substantially more supportive of transformational-transactional integrated approaches than of pure situational flexibility without stable behavioral foundations. The most effective leaders combine a relatively consistent transformational foundation with the situational sensitivity to adapt specific behaviors to follower needs and organizational demands.
