Rework
I read this book over the weekend, and I was really happy with it. It reminded me of their first book “Getting Real”, but “Rework” is less programmer- and startup-oriented, and is more geared to an audience of managers. Each chapter is no more than 3 pages long, but there’s no filler whatsoever: only the essential information you need for each tip is written per chapter.
And there are a LOT of good tips. What are you waiting for? Get it already!
