Question

We interact with information systems every day. For example, libraries have systems that enable you to search for, reserve, and check out books; utilities maintain systems that enable customer service representatives to answer questions about your bill; and your grocery store checkout station is connected to multiple systems that enable the store executives to determine staffing levels, inventory levels, advertising, and promotion efforts.

Select an information system you use on a regular basis.

Create an overview that explains the following:

The type of the information system

The evolution of the selected type of information system. (e.g. the evolution of student financial aid systems in general)

How the information system affected jobs and careers. (e.g. before financial aid systems were developed and which jobs supported the function of financial aid that do not exist today due to technology)

The names of the components used and a description of the purpose or role of each. (Hint: Use information system components you learned so far.)

The benefits this system evolution has brought to you, the organization implementing the change, and other people or organizations within the community

Present your recommendation in following way:

Explanation / Answer

The type of the information system: Automatic Teller Machine (ATM)

Overview: An automatic teller machine (ATM) is a computer based interactive machine that offers several banking services. An ATM can be defined as a computer terminal activated by a magnetically encoded bank card allowing consumers to make deposits, obtain cash from bank accounts, pay bills, transfer money between accounts, print statements and do many other routine transactions as they would at a normal bank teller window. Some U.S. banks have programmed their machines to offer ATM customers access to all banking services available on the bank’s website, effectively duplicating the bank’s website on the ATM display screen. ATMs are known by various other names including automated transaction machines, automated banking machines, money machines, holein-the-wall, bancomats, multibancos and any time money machine.

To use an ATM, customers insert their ATM card into the machine and, using a touch-screen or keypad, enter a personal identification number (PIN) and specify the services desired. Customers can do many things round the clock on ATMs, e.g., deposit and withdraw banknotes, pay bills, deposit cheques, transfer funds.

The ATM should allow its clients to query their current account balances and to withdraw money. If clients want to withdraw money, then the ATM should offer them several amounts, but it should also allow them to choose an amount of money. There are several restrictions. For example, the amount of money clients withdraw should be less than a maximum amount (e.g., $500 for each day), and it should not lower the client’s account balance below a predened lower bound. Furthermore, if clients just query their current account balance, then their account balance should not change.

The evaluation of ATM:

The history of ATMs is open to debate since the cash dispenser’s development occurred long before the machine itself was put into use. Most historians agree that Barclays in London was the first to deploy an ATM in 1967. It was not until the mid-1980s that ATMs started to gain wide acceptance. Then, there was an exponential increase in the number of ATMs. For example, the number of ATMs increased in Saudi Arabia from 462 with 16 million transactions in 1991 to 4842 with 205 million transactions in 2006.

Having become an integral part of many societies around the globe, using the ATM can often be a frustrating experience. Among problems facing users are the ambiguity of menus, inappropriate user–ATM interaction, mismatch between ATM dimensions and anthropometric dimensions of users and the need to reinsert cards to conduct multiple transactions. This latter problem led Curran and King to study whether ATM menus were designed in an optimal manner . They designed an ATM menu system (called OptiATM) which, they ascertained, outperformed navigation systems and was found to be more usable than existing ATM menus. The new system was designed to resolve the problem of users having to reinsert their ATM cards to carry out another transaction and to speed-up transaction times.

Working:

In the ATM example, the mediator role of the designer and the benet of the two models becomes clear. The designer uses the functional design model to communicate with the user and the implementation model to communicate with the software developers. In the software development process, usually one person or a group of people plays the role of the designer and of the software developer.

Careers: There is always a question if ATM has stolen the jobs. But in reality ATMs has given jobs along with eliminating the manual work. The ATM freed the average consumer from lengthy queues for services that had previously been limited to bank hours. As devices spread, this convenience steadily changed patterns of consumption, enabling unplanned weekend shopping and impromptu dining. At the same time, it allowed retail banks to grow their customer base by granting access to consumers who'd previously been excluded from using a current account or a credit card.

To maintain ATMs, many jobs are given to a lot of IT professionals to maintain the functionality. New jobs are given to ATM technicians.

Parts:

Input devices: An ATM has two input devices:

1.      Card reader - The card reader captures the account information stored on the magnetic stripe on the back of an ATM/debit or credit card. The host processor uses this information to route the transaction to the cardholder's bank.

Output devices: An ATM has four input devices:

1.     Speaker - The speaker provides the cardholder with auditory feedback when a key is pressed.

2.     Display screen - The display screen prompts the cardholder through each step of the transaction process. Leased-line machines commonly use a monochrome or color CRT (cathode ray tube) display. Dial-up machines commonly use a monochrome or color LCD.

3.     Receipt printer - The receipt printer provides the cardholder with a paper receipt of the transaction.

4.     Cash dispenser - The heart of an ATM is the safe and cash-dispensing mechanism. The entire bottom portion of most small ATMs is a safe that contains the cash.
