Mastering the Art of Command is a detailed examination of Admiral Chester W. Nimitz's leadership during WWII. It describes how he used his talents to guide the Pacific Fleet, win crucial victories against the forces of Imperial Japan, and then seize the initiative in the Pacific. Once Nimitz's forces held the initiative, they maintained it through an offensive campaign of unparalleled speed that overcame Japanese defenses and created the conditions for victory. This book explores how Nimitz used his leadership skills, command talents, and strategic acumen to achieve these decisive results. Trent Hone recounts how Nimitz revised and adapted his organizational structure to capitalize on newly emerging information. Hone argues that Nimitz was able to couple tactical successes to strategic outcomes and more effectively plan and execute operations that brought Allied victory. Hone explores the challenge of leadership in complex adaptive systems through Nimitz's behavior and causes us to reassess the inevitability of Allied victory and the reasons for its ultimate accomplishment. This book demonstrates effective patterns for complexity-informed leadership by highlighting how Nimitz maintained coherence within his organization, established the conditions for his subordinates to succeed, and fostered collaborative sensemaking.
