Note: Answers
for 10 marks questions should be approximately of 400 words. Each question is
followed by evaluation scheme. Each Question carries 10 marks 6 X 10=60.
Q1. A waiter takes an
order at a table, and then enters it online via one of the six terminals
located in the restaurant dining room. The order is routed to a printer in the
appropriate preparation area, the cold item printer if it is a salad, the hot
item printer if it is a hot sandwich or the bar printer if it is a drink. A
customer’s meal check-listing, bills the items ordered and the respective
prices are automatically generated. This ordering system eliminates the old
three-carbon-copy guest check system as well as any problems caused by a
waiter’s handwriting. When the kitchen runs out of a food item, the cooks send
out an ‘out of stock’ message, which will be displayed on the dining room
terminals when waiters try to order that item. This gives the waiters faster
feedback, enabling them to give better service to the customers. Other system
features aid management in the planning and control of their restaurant
business. The system provides up-to -the-minute information on the food items
ordered and breaks out percentages showing sales of each item versus total
sales. This helps management plan menus according to customers’ tastes. The
system also compares the weekly sales totals versus food costs, allowing
planning for tighter cost controls. In addition, whenever an order is
invalidated, the reasons for the invalidation are keyed in. This may help later
in management decisions, especially if the invalidations are consistently
related to the food or the service. Acceptance of the system by the users is exceptionally
high since the waiters and waitresses were involved in the selection and design
process. All potential users were asked to give their impressions and ideas
about the various systems available before one was chosen.
a. What is the type of information system the above scenario is referring to?
b. How this system does helps later in management decisions related to food
or service based on the reasons for the invalidation which are stored?
c. How this system does helps in finding out the performance of the hotel
form year to year?
Answer. (a) These types of ordering systems
eliminate all the old systems, such as the handwritten bill, which cannot be
easily understood by customers, and wherein it is also very difficult to know
the stock position
Q2. a. With the increase in technology
the business processes have been frequently changed and modified based on the
upcoming requirement of the organization. What is this type of concept called
as?
b. Explain reverse
engineering. How do you improve a process in BPR?
Answer. (a) MIS has an impact on the functional areas
of the organization, and on the organization goals and objectives. MIS are
transaction handling, record keeping, supporting decision making and
disseminating information
Q3. a. While implementing MIS in any
organization change can occur in number of ways. List and explain the steps in
the process as suggested by Lewin’s model.
b. Compare between prototype approach
and Life Cycle approach.
Answer. (a)
The Lewin's model suggests three steps in this
process:-
1. The first step is to communicate openly within the organization.
This makes everyone in the organization look forward to the new system or the
changes with a sense of pride
2. The second step is to outline a list of
Q4. Quality is abstract in nature. It
varies among users and across industries. List and explain the quality
parameters with suitable examples. Also explain the effect of each quality
parameters on information processing.
Answer. 5 parameters:
1.
Controls, internal or external to the situation
2.
Personal dogmatism
3.
Risk Propensity
4.
Tolerance for
Q5. Write short notes on
a. Neural Networks
b. B2B model
with an example
c. DSS Models
d. Administrative control
e. Distributed
database
Answer. (a) Neural Networks (NN):
Neural Networks (NN) is modeled on the basis of the
neuron structure of the human brain. Neuron is a micro cell which is connected
to thousands of other micro cells in the brain.
It is a system which tries to learn from the database
and the manager then decides as to what the right answer is. The entire neural
network is realized in the form of software. The software renders the computer
as a problem solver. The neural
