:''We think there is something like ''the'' cause of a mishap (sometimes we call it the [[root cause]] or the [[primary cause]]), and if we look in the rubble hard enough, we will find it there. The reality is that there is no such thing as ''the'' cause, or [[primary cause]] or [[root cause]]. Cause is something we construct, not find.''<ref>{{fieldguide}}, 33.</ref> | :''We think there is something like ''the'' cause of a mishap (sometimes we call it the [[root cause]] or the [[primary cause]]), and if we look in the rubble hard enough, we will find it there.

===Example=== | |||
Wikipedia gives the following, somewhat implausible example where the problem is that your vehicle will not start. | |||
*Why won’t my car start? – The battery is dead. | |||
*Why is the battery dead? – The alternator doesn’t work. | |||
*Why won’t the alternator work? - The alternator belt has broken. | |||
*Why has the alternator belt broken? – The alternator belt was worn out and not replaced. | |||
*Why was the alternator belt not replaced in time? – The vehicle was not maintained according to its recommended service schedule. | |||
Thus: the root cause is that you didn’t follow a [[second-order derivative]] [[process]]. Now if that seems a little implausible to you, you have at least ''me'' for company. Notice the industry here: to reduce all problems 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]]. | |||
