WHAT IS IT?

Management Information System(MIS) is the most recent subfield of the quantitative school.

A MIS organizes past, present, and projected data from both internal and external sources and processes it into usable information, which it then makes available to managers at all organizational levels.

WHAT IS IT?it is an all-inclusive system for

providing management with better information for effective decision making.

This system is partly a by-product of computer technology which dictates centralisation of data handling and information development for the benefit of entire organisation.

Why Do People Need Information?

Individuals - Entertainment and enlightenment

Businesses - Decision making, problem solving and control

Data, Information, and Systems Data vs. Information

Data A “given,” or fact; a number, a statement, or a picture Represents something in the real world The raw materials in the production of information

Information Data that have meaning within a context Data in relationships Data after manipulation

Data, Information,and SystemsData Manipulation

Example: customer survey Reading through data collected from a customer

survey with questions in various categories would be time-consuming and not very helpful.

When manipulated, the surveys may provide useful information.

Data, Information,and SystemsGenerating Information

Computer-based ISs take data as raw material, process it, and produce information as output.

Data, Information, and SystemsWhat Is a System?

System: A set of components that work together to achieve a common goal

Subsystem: One part of a system where the products of more than one system are combined to reach an ultimate goal

Closed system: Stand-alone system that has no contact with other systems

Open system: System that interfaces with other systems

Data, Information,and SystemsThe Benefits of Human-Computer

Synergy

Synergy When combined resources produce output that

exceeds the sum of the outputs of the same resources employed separately

Allows human thought to be translated into efficient processing of large amounts of data

Data, Information, and SystemsThe Four Stages of Data Processing

Input: Data is collected and entered into computer.

Data processing: Data is manipulated into information using mathematical, statistical, and other tools.

Output: Information is displayed or presented.

Storage: Data and information are maintained for later use.

Why Study IS?Information Systems Careers

Systems analyst, specialist in enterprise resource planning (ERP), database administrator, telecommunications specialist, consulting, etc.

Knowledge Workers Managers and non-managers Employers seek computer-literate professionals who know

how to use information technology.

Computer Literacy Replacing Traditional Literacy Key to full participation in western society

Function of MISInformation systems organize

data into usable and accessible formats.

It stores all the information for better monitoring.

They are used to analyze other information systems applied in operational activities in the organization.

Example of MISThe MIS computer is a useful

accessory,which would store all the information, made available by :-

1. MINOS (mine operating system)2. FIDO (Face Information Digested on line) :-

For face monitoring and for giving the state the key items of the plant on the face.The following reports are available from the system :

a. Shiftwise face delay summaryb. Shiftwise delay logc. Shiftwise and weekly face delay analysis
