Light Out by Gryta and Mann follow up by focusing on the Immelt years and how he tried to keep the ball rolling despite the hole that Jack left him in. Also an excellent read.
Sounds like Power Failure covers a lot of the same material as these two earlier books perhaps with some historical material.
The parts about Boeing in that book are... rough. Not rough as in "poorly-written" but rough as in "holy hell is that ever a brutal way to ruin a good company". Excellent book but lol it's not a feel-good read :)
