I agree.<p>Relevant: <a href="http:&#x2F;&#x2F;web.mit.edu&#x2F;2.75&#x2F;resources&#x2F;random&#x2F;How%20Complex%20Systems%20Fail.pdf" rel="nofollow">http:&#x2F;&#x2F;web.mit.edu&#x2F;2.75&#x2F;resources&#x2F;random&#x2F;How%20Complex%20Sys...</a><p>My experience is that asking five whys can help you manage or mitigate <i>some of</i> the root causes.  You probably won&#x27;t get them all on this pass, but if this is important, it&#x27;ll come up again and you&#x27;ll try some other root causes.  However, if you think you&#x27;ve found <i>the</i> root cause, you&#x27;re probably wrong.  I dunno about &quot;terrifying&quot;, but accumulating scar tissue can definitely create more problems than it solves.
