Typically the Quality Manager will assign the person
responsible to lead the corrective action. That Team
Leader will then select the team members.
The Team should include all functions with
knowledge of the problem (including “process

5 Why Review
&ach response needs to be confirmed with data
Run experiments to confirm that the team’s response to each“why” is accurate.
Don’t allow a dominant team member to state a “fact” without
confirming it.
-ead the “why responses” from the bottom to the top of
the problem statement linking them with “therefore”. All responses should link logically backwards with the word
“therefore”.
