A blameless culture is not a new concept in the technology industry. In fact, in 2012, John Allspaw wrote about how Etsy uses blameless postmortems to dive to the heart of problems when they arise. Other technology giants, like Google, have also worked hard to implement a blameless culture. But what is a blameless culture? Is it just a matter of postmortems? Does it take a culture change to make blameless a reality?
