Leadership On the Line is one of those books built from an original article in the Harvard Business Review but is also in their “Top 10 Must Reads” on Change Management. Heifetz and Linksy describe in detail various hazards of leadership in change, both with theory and real life examples they use from their extensive research, and then what are proven methods to overcome and live through times of change as a leader. I enjoy any book that blends research, real world examples, and a system developed from both that research and real world example, and then even to then continuously validate it with consultation and improvement, that’s the whole improvement cycle right there applied to leadership! I recommend this book for all leaders and change agents practicing leadership and looking to expand their understand of leadership principles in times of strife and change.
