After years of teaching courses in management, Wharton professors Harbir Singh and Mike Useem realized something was missing from the traditional lessons on how to be an effective manager. Most of the instruction seemed to focus on leadership or strategy, emphasizing one or the other. However, the professors contend that the best managers must possess both skills. In their new book, The Strategic Leaders’ Road Map: Six Steps for Integrating Leadership and Strategy, Singh and Useem provide a six-point checklist for managers to develop strategic thinking along with strong leadership skills. The professors visited with Knowledge@Wharton to talk about the book, which is filled with firsthand accounts from CEOs who have been there, done that.
