This book was introduced to me from my employer who brought in John's daughter to introduce us to the QBQ! method.
First off - I have no issues with the message this book is trying to convey, I believe wholeheartedly in the importance of personal accountability and I agree that often times we are too quick to blame in the workplace and don't take enough time looking internally for the solutions to our problems.
However, how does one prevent "silos" from happening if every individual is only looking at what they can do? OF COURSE I agree that the only person you can change is yourself - and that is why personal accountability is so important because you can't change others, BUT if I don't have a fundamental understanding of WHY my company chose to do X or WHY my company hasn't implemented Y ----- then I probably don't have a very good idea of my employer's vision, direction, goal, target outcome, etc. Sometimes one has to ask those questions to better understand what is even going on. I NEED that information to ensure that when I ask "What can I do to support the organization" or "What can I do to be a more effective employee" I'll be on the right track.
While I can't control the people on my team or decide whether or not they will change - if I don't include them in my big picture thinking while I decide how I can contribute - then we aren't acting as a team, we are doomed to become scattered, off track, or duplicate each other's efforts by not realizing someone else has already begun solving X and they're close to finding the solution, so I probably shouldn't start from scratch in my efforts to solve the same thing. I'd probably be better served helping them. But until I ask, What are they doing for the team? I won't know they're working on X, close to a solution, and in need of my help! Your organization will soon become a hackathon, a bunch of people albeit engaged and hard at work, but unknowingly duplicating the same thing and thus wasting energy and wasting efforts that could be put to better use in an orchestrated manner.
I think creating rules on what words can start your sentences and what words can't is too simplistic. The root of the issue is the attitude not what word you use. "What was she thinking when she read my email and responded so rudely?" sounds totally different coming from the place of, I am genuinely trying to put myself in her shoes to see why she reacted to me in that way to see the situation from her perspective so I can understand where she is coming from.
If you have a positive/calm attitude and the mindset of someone who can only control yourself and wants to do everything possible to be a positive force and contribution to your environment, it doesn't matter what word you use to start your sentences with.
I also agree that blame can become toxic but sometimes you do need to address a leaky pipe, rather than do what you can to mop up water but take no action to figure out where the leak is coming from.
Overall, I support the main message, I just don't agree with every example or the oversimplification.
