The purchasing department handles purchase requests from other departments in the company. People in the company who initiate the original purchase request are the “customers” of the purchasing department. A case worker within the purchasing department receives that request and monitors it until it is ordered and received. Case workers process the requests for purchasing products under $1,500, write a purchase order, and then send it to the approved vendor. Purchase requests over $1,500 must first be sent out for a bid from the vendor that supplies the product. In that case, the purchasing department requests for bid where the vendors participate and the vendors develop their bidding strategy. When the bids return, the case worker selects one bid. Then, the case worker writes a purchase order and sends it to the approved vendor. Please Draw a Sequence diagram based on the above information.
