Developing the “code of honor” for the team is the essence of the book.
A team must first establish first the code of honor, by which the team will operate. This is like a ground rules that sets the tone for the team. The author stresses the importance of having the team members develop the code themselves so they can abide by. A good set of code of honor will keep the team going at a time of crisis, much like the marines have been trained to support one another during combat.
A reasonable good book with good examples but did not go into details about building each function of the business team. The message is very simple; I guess the function/expertise is not as important as the cohesiveness and dynamic of a team. The audio book was narrated by the author himself. He’s a natural salesman; he delivers the message with force and conviction. I don’t think you would get as much reading the book.
