"The Gold Mine" by Balle and Balle
The authors intend this to not be your typical business book. And they succeed in this aspect. Balle, a sensei himself, describes how Lean works to save a collapsing hypothetical manufacturing company. He does a good job of describing lean, the tools and, more importantly, the people-aspect of Lean.
Their model for the writing style was The Goal, the now-famous book by Eli Goldratt, in which the author uses the novel as a method of talking about Theory of Constraints. A noble objective, but they fell short.
I found The Gold Mine a difficult read, hardly a page-turner. While the author clearly knows his stuff as a Lean guru, he's not an writer. I felt at many points he quit writing and started typing. The book is at least a third longer than it needs to be, perhaps twice as long. "Lowering the water level" of the inventory of words would have helped.
I didn't finish the book...I just got bored. In reading comments on Amazon's site, I see I'm out of step with others' views, so look at those as well. But I found the book disappointing, simply because it was poorly written. The first time I read The Goal, I sat up till 2:30am to finish it, I could not put it down. I've read it through twice since and still refer to it. No problem laying The Gold Mine down, however.
I hope this is helpful.
