My Reading on ASQ CQA HB Part I-IA~IE-s

Part IA1
Product Audit:
For other services there are
few or no traces of the
service that was performed
and therefore it must be
verified by a process audit,
for example, tuning an engine,
performing repairs, receiving
education or training, and
receiving some personal
services (a haircut can be
checked and verified, but not
a massage).
