- 2. A system is a group of interrelated
components working together toward a common
goal by accepting inputs and producing outputs in an
organized transformation process.
– Components and their attribution
• Systems structure: relationship between components
• Subsystems
– Environment and Boundary
– Input and Output
- 3. The term system may be defined as an orderly
arrangement of a se t of interrelated and
interdependent element that operate collectively
to accomplish some common purpose or goal. For
example – human body is a system, consisting of
various parts such as head, heart, hands, legs and
so on. The various body parts are related by mean
of connecting networks of blood vessels and
nerves and the system has a main goal of “living”.
- 4. Input: Input is what data the system receives to
produce a certain output.
Output: What goes out from the system after
being processed is known as Output.
Processing: The process involved to transform
input into output is known as Processing.
Control: In order to get the desired results it is
essential to monitor and control the input,
Processing and the output of the system. This
job is done by the control.
- 5. Feedback: The Output is checked with the
desired standards of the output set and the
necessary steps are taken for achieving the
output as per the standards, this process is
called as Feedback. It helps to achieve a much
better control in the system.
Boundaries: The boundaries are nothing but the
limit of the system. Setting up boundaries helps
for better concentration of the actives carried in
the system.
- 6. Environment: The things outside the boundary
of the system are known as environment.
Change in the environment affects the working of
the system.
Interfaces: The interconnections and the
interactions between the sub-systems is known
as the Interfaces. They may be inputs and
outputs of the systems
- 7. Formal Information System:
A formal information system is based on the
organization represented by the organization chart.
The chart is a map of position and their authority
relationship, indicated by boxes and connected by
straight lines. it is concerned with the pattern of
authority, communication and work flow.
- 8. The informal information system is
employee based system design to meet
personnel and vocational needs and to help
in the solution of work-related problems. it
also funnels information upward through
indirect channels. In this way, it is
considered to be a useful system because it
works within the framework of the business
and its stated policy.
- 9. Many experts have defined MIS in different language.
A management information system has been defined
by Davis and Olson as “an integrated user-machine
system designed for providing information to support
operational control, management control and decision
making function is an organization”.
Management information system, or MIS, broadly
refers to a computer-based system that provides
managers with the tools to organize, evaluate and
efficiently manage departments within an
organization.
- 10. In order to provide past, present and prediction
information, a management information system
can include software that helps in decision
making, data resources such as databases,
the hardware resources of a system, decision
support systems, people management and project
management applications, and any computerized
processes that enable the department to run
efficiently.
