“We feel lucky to be this popular. I think customers feel we have so many options to offer that they ought to rent an auto from us,” says Ricardo Limon, who manages several outlets for Citron Car Rental. “Our slogan is, ‘You’ll never feel squeezed at Citron.’ We have five sizes of cars that we list A through E:
A. Subcompact
B. Compact
C. Midsize
D. Full-size
E. Luxury
“Standard transmission is available for A, B, and C.
Automatic transmission is available for all cars.”
“If a customer reserves a subcompact (A) and finds on arriving that we don’t have one, that customer gets a free upgrade to the next-sized car, in this case a compact (B). Customers also get a free upgrade from their reserved car size if their company has an account with us. There’s a discount for membership in any of the frequent-flyer clubs run by cooperating airlines, too. When customers step up to the counter, they tell us what size car they reserved, and then we check to see if we have it in the lot ready to go. They usually bring up any discounts, and we ask them if we calculate their rate and write out a slip for them to sign right there.”
Ricardo has asked you to computerize the billing process for Citron so that customers can get their cars quickly and still be billed correctly. Draw a decision table that represents the conditions, condition alternatives, actions, and action rule you gained from Ricardo’s narrative that will guide an automated billing process.
Ricardo wants to expand the ecommerce portion of his business by making it possible to reserve a car over the Web. Draw an updated decision table that shows a 10-percent discount for booking a car over the Web.
Your response should include two decision tables. The first one should contain the conditions and actions described in the case. The second table is expanded from the first to include the conditions and actions for a 10% discount in addition to the discount already listed (in other words, two discounts are listed on the table).
