Managing to Learn by Toyota veteran John Shook, reveals the thinking underlying the A3 management process found at the heart of lean management and leadership. Constructed as a dialogue between a manager and his boss, the book explains how “A3 thinking” helps managers and executives identify, frame, and act on problems and challenges. Shook calls this A3 approach, “the key to Toyota’s entire system of developing talent and continually deepening its knowledge and capabilities.”
