In this landmark book, Anthony J. Mayo and Nitin Nohria break new ground in our understanding of the requirements of truly great leadership. Illustrated through dozens of profiles of business visionaries, In Their Time reveals that outstanding leaders possess more than charismatic personalities and an appetite for risk. They have "contextual intelligence" - a profound ability to understand the spirit of the times and harness the opportunities it presents to create successful organizations. The book identifies three distinct paths that the best leaders forge to greatness - entrepreneurial innovation, savvy management, and transformational leadership - and explores the contextual factors that leaders must "read" correctly in order to succeed.
