Thus: the root cause of your problem is that ''you didn’t follow regulations, you naughty little squirrel''. [[Operator error]]; a failure to attend to a [[second-order derivative]] [[process]]. Now if that seems a little implausible to you, you have at least ''me'' for company. And, I think, {{author|Sidney Dekker}}. And {{author|Charles Perrow}}, were he still around. Notice the industry here: to reduce a problem to a ''fundamental breach of a [[process]]'': a [[heuristic]] or algorithm designed to defend against the intractable messiness of the universe, but which treats that universe like a super-complicated game of [[Go]]. | Thus: the root cause of your problem is that ''you didn’t follow regulations, you naughty little squirrel''.
