An information system that automatically generates report on regular basis and are not used to monitor
input or activities is called:
Open loop system
Closed loop system
Closed end System
Reference - Page No.20
7.3.1 Open-Loop System
The
determinant factor is in an open loop system is that the information
from the system not used for control purpose. This is done by using the
output to generate feed back for control purposes.
• The output is not coupled to the input for measurement.
•
Hence the components of open loop system do not include control and
feedback mechanism due to non-existence of internally defined
objectives. That is,
o Input
o Process
o Output
Example
An information system that automatically generates report on regular basis and are not used to monitor
input or activities.

Question No: 22 ( M a r k s: 2 )
Why prototypes are used?
reference - Page 100
Why prototypes are used?
In
many fields, there is great uncertainty as to whether a new design will
actually do what is desired. New designs often have unexpected
problems. A prototype is built to test the function of the new design
before starting production of a product. Building the full design is
often expensive and can be time-consuming. A prototype allows
manufacturers to rapidly and inexpensively test the parts of the design
that are most likely to have problems, solve those problems, and then
build the full design.
Question No: 23 ( M a r k s: 3 )
Various
considerations need to be kept in mind while defining parameters for
desired output in system designing. What should be them? Identify any

strategy, the less they need to plug the gap with new customers, who are
expensive to recruit.
• CRM help in establishing communication to encourage customers to share information about their
• Habits,
• Tastes and preferences
• Interests in Co’s brand extension initiatives
Question No: 25 ( M a r k s: 5 )
Discuss different types of problems we faced in decision making process?
Page 69 (May be u get better answer from the book )
Types of Problems
Nature of problem determines the approach to decision making to be followed to solve it. There are three broad categories.
• Structured:
Well-structured problems are constrained problems with convergent
solutions that engage the application of a limited number of rules and
principles within well-defined parameters.
• Unstructured:
Problems possess multiple solutions, solution paths, fewer parameters
which are less manipulate able, and contain uncertainty about which
concepts, rules, and principles are necessary for the solution or how
they are organized and which solution is best.
• Semi-structured – a gray area lies between the structured and unstructured range. Here part of the decision can be specified allowing for certain factors out of control.
Question No: 26 ( M a r k s: 5 )
Discuss System Analysis in the light of the following points:
1. A technique to map the system under study.
2. To drill down into the various aspects of the business process without losing sight of the complete system.
PowePage 102
System Analysis
System
analysis can be defined simply as: “The study of business problem
domain to recommend improvements and specify the business requirements
for the solution.”
Or alternatively as:
“A
problem solving technique that decomposes a system into its component
pieces for the purpose of studying, how well those component parts work
and interact to accomplish their purpose.”
Both the definitions highlight following important points:
• System
analysis helps to create an understanding of the business processes,
their linkage with one another, the parameters governing the data flow
within the business, the controls and checks built into the processes
and the reporting needs in a business where a problem exists or for
which the software needs to be designed.
• System
analysis creates the understanding and lays out the necessary
relationships that will assist in defining a solution to the problem or
the design of the proposed software that will meet the user needs.
These two points may be understood as providing a means for undertaking the following tasks:
• A technique to map the system under study.
• To drill down into the various aspects of the business process without losing sight of the complete system.
• To
understand the Workability/Functionality of the subsystems and their
role in achieving the objectives of the system as well as controls and
checks in place.
• To establish the relationship or Level of interaction of each system with other components of the system.red by TCPDF (www.tcpdf.org)
