COMP 4339 – Software Design & Analysis
1. Develop an activity diagram based on the following narrative. If you need to make assumptions, also
note them. Also, note any ambiguities or questions you have as you develop the model. That will
help you to enhance the requirements of the system being developed.
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 the
request and monitors it until it is ordered and received.
Caseworkers process requests for the purchase of 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 bid from the vendor that supplies the product. When the bids return, the
case worker selects one bid, writes a purchase order, archives it, and sends it to the vendor.

The shipping department receives all shipments on outstanding purchase orders. When
the clerk in the shipping department receives a shipment, he or she finds the outstanding
purchase order for those items. The clerk then sends multiple copies of the shipment packing
slip. One copy goes to Purchasing, and the department updates its records to indicate that the
purchase order has been fulfilled. Another copy goes to Accounting so payment can be made. A
third copy goes to the in-house requesting customer so he or she can receive the shipment.
After payment is made, the accounting department sends a notification to the
Purchasing department. After the customer receives and accepts the goods, he or she sends a
notification to the Purchasing department. When the Purchasing department receives these
other verifications, it closes the purchase order as fulfilled and paid.
