Great book! (Although, it could have used a more aggressive editor)
Reading it felt like a personal attack in many places. However, reading it forever changed how I think about things. It's a much more useful framing for everyone involved if you start with the question of "why did they think this was the right thing to do?" as opposed to "this person made a bad choice / mistake". My (extraordinary) impatience naturally predisposes me towards the latter, but the core argument of the book is that that's lazy -- you can hand wave away anything and everything with "operator error".
