• If you use Visio or some other drawing tool, be sure it can be opened without a
password or special software other than Microsoft Office.
• Context Diagram for the new billing and payment system
o This diagram should look similar to the one shown in: Textbook, Systems
Analysis and Design, Page 188
• Diagram 0 for the new billing and system
o This diagram should look similar to the one shown in: Textbook, Systems
Analysis and Design, Page 189 – 190
• Both diagrams will be evaluated on the following
