Now that the team have collected data, reviewed the process flow and added a few patches, if deemed necessary, it is now time to revisit the problem statement identified in the M – module.

The objective of this module is to prove, without a shadow of a doubt, that 100% of root cause has been determined, so it is imperative to ensure we have the correct problem statement.

Update the problem statement if required. Take the time to ensure each team member agrees with the problem statement.
