Dekker was a student of Woods, coined "Just Culture"
Dekker's recent stuff: needs to be a forward thinking "restorative justice", not "retributive justice" (i.e. punishing)
CIO Shopzilla... "when we go into the warroom, the problem is the enemy"
Jason Hand: what do you think of the term post-mortem?... maybe Retrospective, Learning Review? Should "post-mortem" stay?
Can't just describe the behavior... have to describe the context of the behavior.
John tells story of a conversation he had: "what happens when somebody doesn't follow up with something that came up during the postmortem". And during that story, the person who was asked blanked for 30 seconds... because that never happens for them. John says "that's when you know you're nailing culture"
Kevin from Akamai: Setting the cultural tone of "safety" up front
John says: these things make us less fragile, more resilient
John tells netflix story: These are the patterns (circuit breaker, etc), and we're going to start using chaos monkey to knock down instances... you figure it out. And the teams that adopted the patterns are the ones that succeeded
Circuit Breaker, from "Release it!" by Michael Nygard
Alan: fascinated by how these ideas from other industries are making it into our industry
FAA story: previously, for pilots, if you F'd up, you lost your license, which meant you lost your career.
Sounds innovative what we're doing, but IT is late to the game
Greg Elin: a lot of stuff in IT does not have immediate feedback loops, or dire consequences like in the army or airplanes falling out of the sky
John W: at netflix, managers wear pagers
John has hacks for explaining things. For example, John Recommends reading Personal Kanban (Jim Benson) to really understand why WIP limits are so important
Alan: about Rob England (@itskeptic): "ITIL" mindset was all about protect, and devops all about serve... do you want to be the cop or the servant? ITIL all about building in protection, robustness; But DevOps, on the opposite end, can achieve the same ends by seeking resilience instead
check out http://www.itskeptic.org/kamu and http://devopscafe.org/show/2013/3/25/devops-cafe-episode-40.htm l - (Marc: I think I have this a bit wrong) - John says that Rob kind of came around on this; he's going to add the link from a New Zealand devops days where this happened
Jason Hand asks:
