"An Information System (IS) is
the system of persons, data records and activities that process the data and
information in a given organization, including manual processes or automated
processes."
An information system is the basis for
interaction between the user and the analyst. It is an open system that allows
the inputs and facilitates the interaction with the user. It can be defined as
a set of devices, procedures and operating systems designed around the user to
produce information and communicate it to the user for planning, control and
performance.
Information systems deal with the
development, use and management of an organization's IT infrastructure.
A key point to be always remembered when
considering a new alternative system is to be designed to improve planning, control and performance.
In the post-industrial, information age, the focus of companies has shifted
from being product oriented to knowledge oriented. Without keeping this in mind
there would not be any ROI.
The major Information Systems are
1. Formal Information System
2. Informal Information System
3. Computer Based Information System
This is based on the organization
represented by the Organization Chart. The Organization char clearly lays down
the position and the personnel associated to those positions and their
authority relationship.
Formal Information System
This system defines very clearly the
work-flow system, communication flow-down and the authority. The information
flows in terms of policies, goals, strategies, rules and regulations from the
top level management to the bottom level of management.. The information also
flows from the bottom level management to the top level in terms of feedback,
results of work done etc.
Informal Information System
The informal information system should be
employee based and cater to their development and solve their work related
problem. Employee co-operation and the knowledge of the informal communication
should help one to get a good Informal Information Systems in place.
Computer Based Information System
This relies on the computer for handling
business applications. The business requires computer heavily to solve their
business problems. There are different levels of information required by people
at different level. People at Lower Level needs detailed information which
would allow them to carry out with their tasks. People at Higher Level needs
summarized information which would allow them to assess the overall progress,
goals etc. This system should ensure that people at lower level are not given
access to all the data shown at the higher level. However, people at the higher
level can drill down to the data at the lower when required.
