Question No: 17 ( M a r k s: 1 )
On what factors need of information depends in any organization?
Answer:
Good information is
essential for effective operation and decision making at all levels in
businesses. Identifies and illustrates the different kinds of
information by the complex internal and external communication links of a
typical R&D department. Discusses the factors which condition
managers' use of information, namely managers' roles and tasks;
decision-making processes (strategic and operational); rational and
alternative behaviour; cognitive style and perception; and “hidden
agenda” factors such as the symbolic use of information and information
as power. Supported by selected readings, and tables of information
types, processes and uses.

Question No: 20 ( M a r k s: 3 )
What is the need for Accounting information system (AIS) to be linked to all the information systems in an organization. ?
Answer:
Accounting information
system is linked to all the information systems in an organization. This
is important because the data required for proper book keeping and
generation of transactional reports is extracted from all over the
organization. For instance sales information can be sought only from
marketing information system and stock information is available in
manufacturing information system.
The purpose of AIS is to
accumulate data and provide decision makers (investors, creditors, and
managers) with information to make decision.
Question No: 21 ( M a r k s: 5 )
Discuss the attributes on which Organizational Information Requirements depends
Answer:
There are several
surveys indicate that a significant percentage of data warehouses fail
to meet business objectives or are outright failures. One of the reasons
for this is that requirement analysis is typically overlooked in real
projects. Goal-oriented approach to requirement analysis for data
warehouses based on the Tropos methodology. Two different perspectives
are integrated for requirement analysis: organizational modeling,
centered on stakeholders, and decisional modeling, focused on decision
makers. Our approach can be employed within both a demand-driven and a
mixed supply/demand-driven design framework.
Also Functional security
requirements of information systems can roughly be classified into two:
computer security requirements and communications security
requirements. Challenges for developing notations for expressing these
requirements are numerous, most importantly the difficulty of dealing
with layers of abstraction, flexibility to adapt into many types of
requirements, groupings of requirements, and requirement dependencies.
Many frameworks for dealing with information security highlight the
importance of a properly defined organization of security but fail to
establish models to support the specification. This paper establishes
one such model and demonstrates how the above difficulties can be
overcome through extensive application of organizational modeling of
information security.
Question No: 22 ( M a r k s: 10 )
What are the management styles? Discuss in details.
Answer:
Various management
styles can be employed dependent on the culture of the business, the
nature of the task, the nature of the workforce and the personality and
skills of the leaders..
There are three Management Styles.
Authoritative
Participative
Mixed
1)Authoritative
An Autocratic or
authoritarian manager makes all the decisions, keeping the information
and decision making among the senior management. Objectives and tasks
are set and the workforce is expected to do exactly as required. The
communication involved with this method is mainly downward, from the
leader to the subordinate; critics such as Elton Mayo have argued that
this method can lead to a decrease in motivation from the employee's
point of view. The main advantage of this style is that the direction of
the business will remain constant, and the decisions will all be
similar, this in turn can project an image of a confident, well managed
business. On the other hand, subordinates may become highly dependent
upon the leaders and supervision may be needed. Amanda Glass is the
founder of this unique management style.
2) Participative
In a Democraticstyle,
the manager allows the employees to take part in decision making,
therefore everything is agreed by the majority. The communication is
extensive in both directions. This style can be particularly useful when
complex decisions need to be made that require a range of specialist
skills: for example, when a new computerized system needs to be put in
place and the upper management of the business is computer illiterate.
From the overall business's point of view, job satisfaction and quality
of work will improve. However, the decision-making process is severely
slowed down, and the need of a consensus may avoid taking the best
decision for the business.
3) Mixed
This approach is a
combination of both above styles. Input is taken and respected, final
decision is taken by the senior management keeping in view the views
given by the employee.
