This philosophy of McDonald is so important because if the relationship with the supplier is not good they can't provide food to customer in time. We can say that the supplier of raw material is the heart of any business, and McDonald basic philosophy includes the good relation with the supplier. McDonald has to apply this philosophy in any environment without any discrimination for better performance and provide fresh food to customer
