That was a well written article. I think my favorite thing about it, is how it showcases the power of long term thinking over short term thinking. It also showcases an organization that was not using hope as a strategy.
I think the focus on "blameless" is incorrect. It is a culture of responsibility that results in better outcomes and it starts with engaged responsible leaders. Blame is in many ways the opposite of taking responsibility, but you can have a blameless culture without having a culture of responsibility. A culture of blame is always a culture of irresponsibility.
Blamelessness was a function of a leader actively choosing to take responsibility for the problem. They said "it is our organization that is responsible for this tragedy, not the individual." "We caused this through institutional negligence, not the ATCer."
Boeing still has problems because Boeing leadership has not taken responsibility. Boeing leaders have not said "I have created a system of incentives and punishments that have resulted in unsafe airplanes," which is why they are still having safety problems.
The paradox of leadership is that "while a leader is responsible for the actions of the organization, the actions occur from the individual decisions of those who follow."
If the air traffic controller was not consciously making an error, it is a clear problem for leadership to solve. Leadership has a responsibility to make a change. Blame would have prevented that change.
Admiral Rickover brought this culture, a culture of responsibility, to the nuclear navy which has quite a good record of safety. This article echos a good amount of what I have read about Americas Naval engineerng tradition. These are quick short reads to give a taste of Admiral Rickover:

I am very confident that the author would enjoy reading about Admiral Rickover and his philosophy if they have not already.
I also think anyone who enjoyed this article would also enjoy reading Extreme Ownership, which is a much much much better book than the cover and subtitle implies and is applicable to every job in silicon valley.
