“Ithink we have everything we need. I’ve sampled financial statements, sales figures for each branch,wastage for each shop—we have it all. With all these numbers, we should be able to figure out how to keep Fields in the green, or at least at the forefront of the flower business. We can even show Seymour Fields himself how his new computer system can make it all happen,” says Rod Golden, a junior systems analyst working for a medium-sized consulting group. The firm, under the supervision of its head systems analyst, Clay Potts, has been working on a systems project for the entire chain of 15 successful florist shops and indoor floral markets called Fields. Each of three Midwestern cities has five Fields outlets. “Although it’s just a budding enterprise now, eventually we want to grow with offshoots to half a dozen states,” says Seymour Fields, the owner. “I want to reap the benefits of all the happiness we’ve sown so far. I think we can do it by playing my hunches about what is the best time to purchase flowe
“Real or fake? Fake or real? Who would have thought it, even five years ago?” howls Sam Pelt, a furrier who owns stores in New York; Washington, D.C.; Beverly Hills; and Copenhagen. Sylva Foxx, a systems analyst with her own consulting firm, is talking with Sam for the first time. Currently, P & P, Ltd. (which stands for Pelt and Pelt’s son) is using a PC that supports package software for a select customer mailing list, accounts payable and accounts receivable, and payroll. Sam is interested in making some strategic decisions that will ultimately affect the purchasing of goods for his four fur stores. He feels that although the computer might help, other approaches should also be considered. Sam continues, “I think we should talk to all the customers when they come in the door. Get their opinions. You know, some of them are getting very upset about wearing fur from endangered species. They’re very environmentally minded. They prefer fake to real, if they can save a baby animal. Some even like fakes better, c
“I love my work,” Tennys says, beginning the interview with a volley. “It’s a lot like a game. I keep my eye on the ball and never look back,” he continues. Tennyson “Tennys” Courts is a manager for Global Health Spas, Inc., which has popular health and recreation spas worldwide. “Now that I’ve finished my MBA, I feel like I’m on top of the world with Global,” Tennys says. “I think I can really help this outfit shape up with its computers and health spas.” Tennys is attempting to help your systems group, which is developing a system to be used by all 80 outlets (where currently each group handles its paperwork in its own way). “Can I bounce this off you?” he asks Terri Towell, a member of your team of systems analysts. “It’s a questionnaire I designed for distribution to all spa managers.” Ever the good sport, Terri tells Tennys that she’d love to take a look at the form. But back in the office, Terri puts the ball in your court. Systematically critique Tennys’s technique as depicted in Figure 4.C2, and expla
Know what I think of the work the last systems analyst team did? The printouts created are a jungle. To figure out the cost of raw materials to us, I have to cut my way through the overgrowth of data, hacking my path with a pen. I cross out everything that’s irrelevant. Sometimes I physically rip out the excess vegetation until I reach the numbers I need,” says Henry Stanley, accounting supervisor for Zenith Glass Company. As you interview him, he points unhappily to an untidy stack of mutilated printouts sprouting beside his desk. Identify the overriding metaphor Henry is using to describe the printouts he is receiving and the accessibility of information in them. In a paragraph, describe how this step helps you understand Henry’s attitude toward any work proposed by your systems analysis team. In a paragraph, adopt Henry’s metaphor and extend it in a more positive sense during your interview with him.

The development team of SoftSols Inc. has revamped the software according to the requirements
of FlyHigh Airlines and is in the process of testing the software. While testing the software, the
team encounters the following issues:
The operations-related data of FlyHigh Airlines is stored in a central database. The software
fails to respond to user inputs, if there is a connectivity problem with the database. Add the code
snippet that the development team should use to ensure that the application shows a userfriendly
message, if such a situation arises in future.[5 Marks]
The application used to calculate the cost of carrying additional luggage results in erroneous
amount, if the weight of the luggage is a fractional number. Help the development team modify
the code snippet so that the cost of carrying additional luggage is calculated correctly. [5 Marks]

FlyHigh Airlines allows each passenger to carry limited amount of luggage per ticket. The
maximum amount of luggage that can be carried by a passenger depends on the class in which
the passenger is travelling. The following table lists the maximum amount of luggage allowed for
each class.
If a passenger carries luggage above the maximum amount permissible for the class in which
he/she is travelling in, the passenger is levied an additional cost at the rate of $2/additional KG.
Currently, this cost is calculated manually, which is a time consuming process. Therefore, the
management of FlyHigh Airlines has asked SoftSols Inc. to create an application that accepts the
total weight of a luggage carried by a passenger, checks whether it is more than the maximum
amount allowed for the passenger's class of travel, and then calculates the additional cost that
needs to be levied on the passenger. In addition, SoftSols Inc. needs to ensure that the application
is able to handle the weight of luggage in whole numbers as

The development team of SoftSols Inc. analyzes the source code of the existing software and
notes the following observations:
The software contains a private class, named bookTickets, that contains the methods used to
perform ticket bookings for various flights.
There is no class or function that can be used to check the maintenance details of FlyHigh's
aircrafts.
Based on the preceding observations, the development team decides to perform the following
tasks:
Reuse the functions of the bookTickets class in a new class, named bookETicket, to add the
feature of e-ticket booking.
Create a new class named viewMaintenance that allows the maintenance personnel of FlyHigh
Airlines to view the maintenance details of aircrafts.
Write the code snippet that the development team should use to accomplish each of the preceding
tasks. [10 Marks]
