A company culture of openly admitting mistakes, knowing that your team-mates will not play the blame game, means that problems will be reported quickly.
In a "conventional" culture, an engineer who makes a mistake (and who will be fired for making that mistake) is incentivised to cover up the mistake and hope that the blame falls elsewhere.
In an open culture, the engineer who makes a mistake is incentivised to immediately raise the alarm.
So while the chances of a mistake happening are the same (we're all human), the chances of it being caught quickly and dealt with quickly are better in an open culture.
It also brought to my attention how much they've progressed as a platform since I used them last.
