Keep asking why.
The first explanation is usually a symptom. Keep asking why until you reach something the team can fix for good.
Five Whys · Fictional Example
The Problem
New customers are leaving within 60 days.
Why?
Their number porting took weeks, not days.
Why?
Every port request is checked by hand.
Why?
There's no automated validation of port forms.
Root Cause
Nobody owns the porting experience end to end.
The fix: give porting an owner and a target, and automate the checks. Faster ports follow.
