What is MIS? Define the characteristics of MIS? What are the basic Functions of MIS? Give some

Disadvantage of MIS?

Organized approach to the study of information needs of a management at every level

in making operational, tactical, and strategic decisions. Its objective is to design and

implement man-machine procedures, processes, and routines that provide suitably

detailed reports in an accurate, consistent, and timely manner. Modern, computerized

systems continuously gather relevant data, both from inside and outside the

organization. This data is then processed, integrated, and stored in a centralized

database (or data warehouse) where it is constantly updated and made available to all

who have the authority to access it, in a form that suits their purpose.

Characteristics of MIS:

MIS is mainly designed to take care of the needs of the managers in the organization.

MIS aids in integrating the information generated by various departments of the

organization.

MIS helps in identifying a proper mechanism of storage of data.

MIS also helps in establishing mechanism to eliminate redundancies in data.MIS as a system can be broken down into sub systems.

The role and significance of MIS in business and its classification is explained. It is

possible to understand the various phases of development in MIS based on the type of

system required in any organization.

Functions of MIS

1. Data processing

It includes the collection, transmission, storage, processing and output of data. It

simplifies the statistics and reduces to the lowest cost by supplying an unified format.

2. Function of prediction

It predicts the future situation by applying modern mathematics, statistics orsimulation.

3. Function of plan

It arranges reasonably the plans of each functional department in accordance with therestrictions afforded by enterprises and provides the appropriate planning reports

according to different management.

4. Function of control

It monitors and inspects the operation of plans and comprises with the differences

between operation and plan in accordance with the data afforded by every functional

department, and be assistant to managers to control timely each method by analyzing

the reasons why the differences comes into being.

5. Function of assistanceIt derives instantly the best answers of related problems by applying to various of

mathematics’ mode and analyzing a plentiful data stored in computers in the hope of

using rationally human resource, financial resource, material resource and information

resource for relative abundant economic benefits.

Disadvantages of MIS

1.highly senstive requires constant monitoring.

2.buddgeting of MIS extremely difficult.

3.Quality of outputs governed by quality of inputs.

4.lack of flexiblity to update itself.

5.effectiveness decreases due to frequent changes in top management

6.takes into account only qualitative factors and ignores non-qualitative factors like

morale of worker, attitude of worker etc..

2. Explain

Knowledge based

system?

Explain DSS and

OLAP withexample?Answer:

Knowledge BasedSystem (KBS)

KBS are the

systems based

on knowledge

Knowledge base

is thedatabasemaintain

ed for knowledge

management

which provides

the means of data

collections,organ

ization and

retrieval of knowledge. The

knowledge

management

manages

thedomain

where it creates

and enables

organization foradoption of

insights

andexperiences.T

here are two types

of knowledge

bases.a. Machine

readable

knowledgebases: The

knowledge base

helps the

computer

to process

through. It

makes the data

in the computerreadable code

which makes

theoperator to

perform easier.

Such information

sare used by

semantic web.

Semantic web isaweb that will

to be processed

by the reader.The reader can

accessthe

information and

synthesize their

own.KBS refers

to a system of

data and

information usedfor decision

making. The

system

isautomated to

work on the

knowledge based

data and

informationrequired in a

particular domain

of management

activity. The

processing is

done based on the

past decisions

takenundersuitable

conditions.

Decision making

is based on the

fact that the

condition

issimilar to the

past situationhence the

decision is also is

similar.Examples

of KBS are

intelligent

systems, robotics,

neural networks

Online Analytical

Processing

(OLAP)

OLAP refers to asystem in which

there arepredefined

multiple

instances of

variousmodules

used in business

applications. Any

input to such a

system results inverificationof the

facts with respect

to the available

instances.A

nearest match is

analytically and

the resultsdisplayed form

the database.

Theoutput is sent

only after

thorough

verification of

the input facts

fed to the system.Thesystem goes

through a series

of multiple

checks of the

various

parameters used

in business

decision making.OLAP is also

referred to as a

dimensional

analyticalmodel.

Many big

companies use

OLAP to get goodreturns in

business.- 3 -

The querying

process of the

OLAP is very

strong. It helps

the management

take decisionslikewhich month

would be

appropriate to

launch a product

in the market,

what should bethe

production

quantity tomaximize the

returns, what

should be the

stocking policy

inorder to

minimize the

wastage etc.A

model of OLAPmay be well

represented in the

form of a 3D box.

There are six

facesof the box.

Each adjoining

faces with

common vertexmay be

considered to

represent

thevarious

parameter of the

business situation

consideration.E.g.: Region, Sales &

demand, Product

Model of OLAP

Decision Support

Systems (DSS)DSS is an

interactive

computer based

system designed

to help the

decision makers

to useall l the

resourcesavailable and

make use in the

decision making.

In management

many atime

problems arise

out of situations

for which simplesolution may not

be possible.

Tosolve such

problems you

may have to use

complex theories.

The models that

wouldberequired to

solve such

problems may

have to be

identified. DSS

alternatives, given

past experience in

a contextthat is

described.Manag

er may

sometimes find itdifficult to solve

such problems.

E.g. – In a

sales problem if

there is multiple

decision

variables

modeled as asimple linear

problem

buthaving

multiple optima,

it becomes

difficult to take a

decision. Since

any of themultipleoptima

would give

optimum results.

But the strategy to

select the one

most suitable

under conditions

prevailing in themarket, requires

skills beyond the

model.It would

take some trials to

select a best

strategy. Under

circumstances itwould beeasy to

take decision if a

ready system of

databases of

various market

conditions

andcorresponding

appropriatedecision is

available. A

system which

consists of

database pertainin

g to decision

making based on

certain rules isknown as

decision support

system.It is a

flexible system

which can be

customized to suit

the organization

needs. It canwork in the

interactive mode

in order to enable

managers to take

quick decisions.

You canconsider

decision support

systems as thebest when it

includes high-

summaryreports

or charts and

allow the user to

drill down for

more detailedinformation.A

DSS has the

capability to

update its

decision database.

Whenever

manager feels that

a particulardecision is

unique and not

available in the

system, the

manager can

chose toupdate

the database with

such decisions.This will

strengthen the

DSS to take

decisions

infuture.There is

no scope for

errors in decision

making whensuch systems are

used as aid

todecision

making. DSS is a

consistent

decision making

system. It can be

used togeneratereports of

various lever

management

activities. It is

capable of

performing

mathematicalcalc

ulations andlogical

calculation

depending upon

the model

adopted to solve

the problem. You

can summarize

the benefits of DSS into

following:•

Improves

personal

efficiency•

Expedites

problem solving•

Facilitatesinterpersonal

communication•

Promotes learning

or training•

Increases

organizational

control•

Generates newevidence in

support of a

decision• Creates

a competitive

advantage over

competition•

Encourages

exploration anddiscovery on the

part of the

decision maker •

Reveals new

approaches to

thinking about the
