I agree on your review of both books. Phoenix project was excellent. After years of banging my head trying to change a large org, I'm not sure you can do it head on. I found either you need incentives to change, then the org changes. e.g. Rather than encourage goal X, pay or promote teams that do X and it will happen (subject to some level of faking). Or more usually use the current org structure to affect change. i.e. play their game, then use the parts you can to make change. Trying to change an org head on never worked for me and just caused myself and otehrs great unhappiness :).
