Todays managers
depend on information systems for decision making. The managers have
handful of data around them but manually they cannot process the data
accurately and with in the short period of time available to them due to
heavy competition in modern world. Therefore mangers depend on information
systems.
The concept of MIS:
Management: Management has been defined in a
variety of ways, but for our purposes it comprises the process or
activities what managers do in the operation of their organization: Plan,
Organize, Initiate and Control operations.
Information:
Data are facts and figures that are not currently being used in
a decision processes and usually take the form of historical records that
are recorded and filed without immediate intent to retrieve for decision
making.
Information consists of data that have been retrieved,
processed or otherwise used for information or inference purposes,
argument, or as a basis for forecasting or decision making.
System can be described simply as a set of elements joined
together for a common objective. A subsystem is is part of a larger system
with which we are concerned. All systems are part of larger systems.
The objective of an MIS (Management Information System) is to provide
information for decision making on planning, initiating, organizing, and
controlling the operations of the subsystems of the form and to provide a
synergetic organization in the process.
Decision Support System: It is sometimes described as the next
evolutionary step after Management Information Systems (MIS) . MIS
support decision making in both structured and unstructured problem
environments.. It supports decision making at all levels of the
organization .IS (Information Systems) are intended to be woven into the
fabric of the organizations , not standing alone. IS support all aspects
of the decision making process.MIS are made of people, computers,
procedures, databases, interactive query facilities and so on. They are
intended to be evolutionary/adaptive and easy for people to use.

MIS is a technique for making programmed decisions. If we include
the computer and management science as integral parts or tools of computer
–based information systems, the prospects for a revolution in
programmed decision making are very real. Just as a manufacturing process
is becoming more and more automated so is the automation of programmed
decisions increasing to support this production and other information
needs through out the organization.
