I find Business books fall into two categories, psychological research then applied to business, or a group of tactics from a particular persons experience.

This is the latter, and because of it, if your organisations aren't like the organisations of the author, you might struggle to apply these.

Having said that, of the books I have read that are like that, this is by far the best, and takes a kind, learning and systems thinking based approach to most of the tactics described within.

The advice is practical and I can see myself using it as a reference. As it's from a collection of blog posts I would recommend treating each part as a single isolated unit, rather than viewing the work as whole.
