Assume that if the product requested is not in stock, it needs to be manufactured before the order handling can continue. In this way, an order can never be rejected.
To manufacture a product, the required raw materials have to be ordered. Two preferred suppliers provide different types of raw material. Depending on the product to be manufactured, raw materials may be ordered from either Supplier 1 or
Supplier 2, or from both. Once the raw materials are available, the product can be manufactured and the order can be confirmed. On the other hand, if the product is in stock, it is retrieved from the warehouse before confirming the order. Then the process continues normally. After confirming the order, the shipment address is received and the requested product is shipped while the invoice is emitted and the payment is received. Afterwards, the order is archived and the process completes.
