I appreciated that this book helped me identify some territorial games I see at work, because that's the first step to addressing them.
However, I found the author's writing style too colloquial, and her choice not to cite sources in the text made the content seem less credible. I was also disappointed by the suggestions for avoiding territorial games. I think they were realistic, but they took a top down approach (essentially, they were tactics that a director or VP could use with their teams, not someone at the bottom of the org structure). I also agreed with the author that the only way to get people to change is to make them want to, but I didn't take away any recommendations on how to achieve that.
