Leadership is the influencing process of leaders and followers to achieve organizational objectives through change (Lussier & Achua, 2010, p. 6).
According to Rosch and Kusel (2010), leadership is commonly defined as “an individual’s influence on a group in order to reach a goal” (p. 29).
Boseman (2008) referred leadership as the "act of stimulating, engaging, and satisfying the motives of followers that result in the followers taking a course of action toward a mutually shared vision" (p. 36).
Leadership is typically viewed as a process of social influence, in which one or more persons affect one or more followers by clarifying what needs to be done, and providing the tools and motivation to accomplish set goals. (Babcock-Roberson & Strickland, 2010, p. 314)
Leadership is a skill used to influence followers in an organization to work enthusiastically towards goals specifically identified for the common good (Parris & Peachey, 2013, p. 377)
Leadership is both an art and a science that must be learned and practiced - and that practice is ongoing (Cardillo, 2010, p. 12).
According to Passmore (2010), leadership is “a set of social processes of influencing and motivating individuals and groups, and of shaping goals and outcomes amongst diverse stakeholders through influence, persuasion and negotiation” (p. 160).
A useful definition of leadership is "the reciprocal process of mobilizing, by persons with certain motives and values, various economic, political, and other resources, in a context of competition and conflict, in order to realize goals independently or mutually held by both leaders and followers" (Burns as cited in Passmore, 2010, p. 160).
Winston Churchill defined leadership concisely as the ability to influence people to set aside their personal concerns and support a larger agenda—at least for a while. Churchill made it clear that effective leaders motivate people to perform above and beyond the call of dut)- in order to enhance group success. To him, leadership effectiveness was not who exerts the most influence or who emerges to control the group; rather, the leader is the one who can achieve high group performance over time. In today's language, we would say that Churchill su^ested that effective leadership is perhaps the best source of organizational competitive advantage (Boseman, 2008, p. 36).
