The Goal: A Process of Ongoing Improvement
by Eliyahu Goldratt and Jeff Cox
This very quirky (and charmingly/annoyingly dated) book, set in a manufacturing plant, contains the single most important CEO insight we’ve seen, which is to focus your energy on identifying and unlocking the primary constraint of the business. Any problem that is not connected to the primary constraint, while it may feel good to solve, doesn’t do anything to move the business forward. You can’t be a 10X CEO until you grasp and live by this insight.
