Book excerpt: Fast. Motivated. Hard-hitting. That's what every business wants to be. And that's why the U.S. Marines excel in every mission American throws at them, no matter how tough the odds. In Corps Business, journalist David H. Freeman identifies the Marine's simple but devastatingly effective principles for managing people and resources -- and ultimately winning. Freedman discusses such techniques as "the rule of three," "managing by end state," and the "70% solution," to show how they can be applied to business solutions.
