Byron writes that, "In Jack: Straight from the Gut, Welch tells an entertaining story... meant to illustrate Welch's willingness to make gutsy, out-on-a-limb decisions..." The story in question, involving the development and commercialization of a plastic called Noryl, is "presented as the breakthrough moment of his career, without which his abilities as a leader would never have been recognized by higher-ups."
In reality, Byron shows us, Welch was really only out on a limb as the main proponent of a new plant for Noryl, being constructed even before long-standing and intractable production problems had been solved. Welch lauds himself for solving the problem, when the solution actually came from an obscure former GE chemical engineer named Eric Cizek who left his notebooks behind after being fired for spending so much time working by himself in the lab.
Without this accidental discovery, the new plan would probably have been a failure -- and no one would have heard of Jack Welch, all his wives, girlfriends and mistresses, or the suicide of Regina Paulsen, a secretary who worked amid the sexually charged atmosphere of the people Welch managed and hung out with. Byron writes that Regina "apparently morphed during her brief GE career from a quiet young woman who minded her own business into a kind of wild party animal who was getting passed around among" Welch's group.
