@grimalkina Reality checking versus superstition for the individual developer or dev team, perhaps?
At work we learn what we experience in the context we find it. Sometimes the context encourages understanding, and sometimes it encourages explaining away the "why" without checking.
This morning's CoffeeOps peer discussion highlighted operations "game days", rehearsing failure scenarios, as a way to exercise and transfer working knowledge, to work across teams in the response, and test assumptions. Sometimes the incident response books get confirmed, and sometimes rewritten.
