Joel reviews Goldratt.

I read the Goal a long time ago, and thought it was good, but don't remember why. Critical Chain I read a couple years ago and found rather insightful. Besides the things Joel points out, it underscored for me something I call The Matress Principle. I should figure out what that means again. It was very important. (Just kidding, I remember what it means, but I should write it down.)
