there is no root cause

"What you call root cause is simply the place where you stop looking any further" -- Sidney Dekker "Overt catastrophic failure occurs when small, apparently innocuous failures join to create opportunity for a systemic accident. Each of these small failures is necessary to cause catastrophe but only the combination is suffjcient to permit failure." -- Richard Cook
