Thanks, really enjoyed that foreword and it really pushed High Output Management up on my reading list. Plus as a bonus I finally learned the name of "The Peter Principle" (the idea that people in a hierarchy tend to rise to their level of incompetence).
The Peter Principle book is awesome too, by the way. Highly recommended!
The peter principle and the dunning kruger effect define the majority of leadership I see these days.
High Output Management is required reading at my startup. But so is Horowitz's book [0], which I think is actually better.
