Need to make visual DFD Model using Visio. following:

Sometimes you just never know what job you're going to have. Our consulting firm has just been hired by Cougs' Quick Cuisine (CQC) to develop a system to record orders for pizza, Buffalo wings, and spirits. When regular customers call CQC) on the phone, they are asked for their phone number. When the number is typed into a computer, the name, address, and last order date is automatically brought up on the screen. If the customer is new, then they are added to the system. Once the order is taken, the total, including tax and delivery, is calculated. Then the order is given to the cook. A receipt is printed. Door Dash drivers give customers a copy of the receipt and a coupon (if any). Weekly totals are kept for comparison with last year's performance. Here is what we need to do for CQC:

1. Write a summary of business activities for taking orders at GDP (Hint: I used 6).

2. Draw the logical level O DFD for GDP, creating the Level O DFD.

3. From the level O DFD, create the associated context level DFD for GDP. NOTE: This is an iterative process of moving back and forth between the levels, so you may have to update you context level and level 0 diagrams multiple times. Good Luck!
