root cause analysis: 
We must understand that a problem has many underlying causes.
To find the underlying causes from different perspectives.

…Bieber fever?

causes of the cause?
Humans? …probably.

With causes, we need to find evidence. 
how to find the root cause?

use the ladder of Y's. Find the root cause, and work your way out.
