hi all
recently I'm confused about the four
kinds of requirement as follows:
customer requirement
product requirement
internal requirement
work requirement;
I know that product requirement is
for products that are purchased
from an external suppliers. When this
kind of requirement is approved, it can
be aggregated into a purchase order.
And the internal requirement is for
products that are manufactured internally.
My problem is that what is the customer
requirement and work requirement for?
waiting for your help.
thanks.
