PERFECT PIZZA
PERFECT PIZZA wants to install a system to record
orders for pizza and chicken wing. When regular customers call PERFECT PIZZA
on the phone, they are asked for the phone number. When the number is typed
into a computer, the name, address and last order date is automatically brought
up on the screen. Once the order is taken, the total, including tax and
delivery charges is calculated. Then the order is given to the cook. A receipt
is printed. Occasionally special offer coupons are printed so the customer can
get a discount. Drivers who make deliveries give customer a copy of the receipt
and a coupon (if any). Weekly totals are kept for comparison with last year’s
performance.
