『Turn the Ship Around!』要約

In *Turn the Ship Around!*, former U.S. Navy captain L. David Marquet recounts his experience taking command of the USS Santa Fe, a nuclear submarine widely regarded as one of the worst-performing in the fleet, and turning it into a top performer by abandoning traditional top-down leadership. Marquet had trained to command a different submarine and was reassigned late to the Santa Fe; rather than learn every technical detail of an unfamiliar vessel, he changed how authority flowed through it. The book’s central framework is “leader-leader” as opposed to the Navy’s conventional “leader-follower” model. Instead of issuing orders that sailors passively obeyed, Marquet pushed decision-making down to the people closest to the work. A key mechanism is “deliberate action”: before acting, crew members state their intention aloud, giving others a chance to catch mistakes. Another is “thinking out loud,” where subordinates propose decisions rather than asking permission, using the phrase “I intend to…” in place of “I request permission to…”. He also describes abolishing the practice of asking for approval, emphasizing technical competence, clarity, and courage as the prerequisites for distributed control. Marquet illustrates these ideas through concrete episodes aboard the Santa Fe, including watch-standing, maintenance, and inspection drills, and through the ship’s turnaround in retention and operational performance. The book’s broader argument is that enduring excellence comes from giving people ownership and the authority to act, not from charismatic commanders. It is presented as a narrative of organizational change, with the submarine serving as the experiment and the crew as its participants. The title’s metaphor is turning the ship’s direction by shifting control to those doing the work.
