I don't buy almost any of it. The thing is - it's very hard to compare performance between projects and teams. What author considers "high-performance" might mean "environment I felt productive in" and so on. Don't get me wrong. It might all be good advice and work well, or it might not. Or might work in some contexts, but not in other. And it's all just an opinion.
