What is the long term (LT) demand? Are there sufficient resources to produce the demand in the time that it is need and on the product road-map? How are production assurance and product costs balanced to fulfill demand at an optimum cost?
One plant/supplier always meets demand and with quality thus minimizing downstream warranty or scrap issues but they are the highest cost, lowest volume producer. Another plant/supplier is low cost/high volume but with higher scrap. So, disburse manufacturing/supply wrong and have high quality but insufficient product or sufficient product but with warranty and scrap costs.
