The initial lot of any 4M change without 1st lot notification is unacceptable. So please do your internal improvement
by use this lesson learnt as well.
Fortunately, this change is just only the improvement by both UOI and DGT procurement so we do not get
any affect to product quality. If it's design or engineering change, this might impact to DGT production and
product quality also.
I expect that we will not have the trouble like this case again in the future.
