Question No: 20 ( M a r k s: 1 ) http://vuzs.net
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: 21 ( M a r k s: 2 )
Enlist the types of models used in DSS.
Page 48
Types of Models Used in DSS
• Physical Models
• Narrative Models

• Mathematical Models
 
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 three.
 
Question No: 24 ( M a r k s: 3 )

• Gaining more customers’ wallet-share
• The more effective a company's customer retention and defection management 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)
