The former CEO of The Home Depot, Robert Nardelli, employed many unpopular but arguably successful tactics during his tenure as leader. Through the process of centralization of purchasing processes, diversification of services offered and additional customer base catered to, and an eventual shift in corporate culture, Robert Nardelli changed the way the company operated from the bottom up. Many theories can be applied to the leadership style used by Robert Nardelli, from certain trait theories describing which traits were important for successful leadership, to behavioral theories outlining how the leader approached and prioritized the important factors in a business. In addition, the leadership style employed can be dissected using situational and contingency theories – allotting certain styles of leadership to the exact function they serve, including specific nuances of the dynamic between leader and follower. No matter the theory used to describe actions taken by leaders, the question of ethical behavior can be answered through an analysis of the intentions of, and outcomes due to, the leader themselves.
