At first I was really resistant to reading this. "No excuses" sounds like something someone who has never been responsible for impossible engineering deadlines gets to say. But, I really like the way Blank defines it as "be in communication and ask for help so there are no surprises." That is great: I often find myself avoiding being in communication because I'm sure someone will offer uncomfortable solutions. But, those are the difference between a mediocre organization and a superb one.
