M = Management = Practical Use of Power of Decision Making
I = Information = Useful Data
S = System = Technique of Use of Data for Business
Now, we are able to introduce Management Information System.
MIS STANDS FOR…..
![Page 10: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/10.jpg)
A management information system (MIS) is a system that provides information needed to manage organizations effectively.
MIS Provide information in the form of reports and displays to managers to support business decision making.
It is a sub part of information system.
What is “MIS”??
![Page 11: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/11.jpg)
An MIS provides managers with information and support for effective decision making.
provides feedback on daily operations
Output(reports), are usually generated through accumulation of transaction processing data
Each MIS is an integrated collection of subsystems, which are typically organized along functional lines within an organization.

Scheduled reports Produced periodically, or on a schedule (daily, weekly,
monthly)
Key-indicator report Summarizes the previous day’s critical activities Typically available at the beginning of each day
Demand report Gives certain information at a manager’s request
Exception report Automatically produced when a situation is unusual or
requires management action
Outputs of MIS

Provides reports with fixed and standard formats◦ Hard-copy and soft-copy reports
Uses internal data stored in the computer system
MIS eliminates redundant data
End users can develop custom reports
Requires formal requests from users
It promotes security system by providing only access to authorized users.
Characteristics of a MIS
![Page 17: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/17.jpg)
Provides support to managers as they work to achieve corporate goals.
Enables managers to compare results to established company goals and identify problem areas and opportunities for improvement.
Management Information Systems for Competitive Advantage
![Page 18: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/18.jpg)
Applications of MIS.
![Page 19: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/19.jpg)
Provide financial statements and performance reports to assist in the planning, monitoring and implementation of strategy.
MIS systems can also use these raw data to
run hypothetical scenarios like ‘what if’ questions.
For instance, MIS systems can provide predictions about the effect on sales that an alteration in price would have on a product.
*Strategy Support
![Page 20: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/20.jpg)
MIS provide a valuable time saving benefit to
the workforce.
In past business information had to be manually processed for filing and analysis
Now it can be entered quickly and easily onto a computer by a data processor, allowing for faster decision making and quicker reflexes for the enterprise as a whole.
* Data Processing
![Page 21: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/21.jpg)
MIS also be of use as a Management by Objectives (MBO) tool.
MBO is a management process by which managers and subordinates agree upon a series of objectives for the subordinate to attempt to achieve within a set time frame.
Objectives are set using the SMART ratio: that is, objectives should be Specific, Measurable, Agreed, Realistic and Time-Specific.
Management by Objectives
![Page 22: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/22.jpg)
a) Quicker information availability
b) Anytime anywhere access to information
c) Promotes non redundancy
d) Quick decision-making
e) Fast actions undertaken
f) Effective productivity
g) Reduced transaction rate

Decision support system
Dss used to describe a computer-base system designed to help decision makers use data, knowledge &
communication technology to identify problems & make decision to solve
those problems.
![Page 29: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/29.jpg)
Categories of dss
Dss system can be separated into seven broad categories,
Communication driven DSS Data driven DSS Document driven DSS Knowledge driven DSS Model driven DSS Spreadsheet base DSS Web based DSS
![Page 30: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/30.jpg)
communication driven dss
C-D DSS is a type of dss that enhance decision making by enabling communication & sharing of information b/w the group of people.
![Page 31: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/31.jpg)
Data- driven dss
Data Driven DSS are a form of support system that focuses on the provision of internal & sometime external data aid decision making.
![Page 32: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/32.jpg)
Document- driven dss
Document driven DSS are support system designed to convert documents into valuble business data.
the three primary forms of data used in document driven DSS are,
oral written videos
![Page 33: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/33.jpg)
Knowledge driven dss
Knowledge driven DSS are systems designed to recommand action to user. K-d DSS model uses special rules stored in computer or used by a human to determine whether a decision should be made. These rules or fact are used in order to make a decision.
![Page 34: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/34.jpg)
Model Driven DSS
Model Driven DSS is when decision maker s use statistical, simulation or financial model to come up with a solution.
![Page 35: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/35.jpg)
Spreadsheet- base
Spreadsheet offers decision makers easy to understand representation of large amount of data. Spread sheet data is arrange in such a way as to make it easy to convert the data into visualisation to further aid decision makers.
![Page 36: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/36.jpg)
Web Based DSS
The term simply describes any decision support system that is operate through interface of web browser, even if the data used for decision support remains confined to a legacy system such as a data warehouse.
![Page 37: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/37.jpg)
Scope of DSS
Enterprise wied DSS

Enterprise-Wide DSS
Enterprise – wide DSS are system that are linked into large warehouse, & offer decision support to manager at all level of an enterprise.
![Page 39: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/39.jpg)
Desktop DSS
Desktop Dss are much smaller application designed to be run from a desktop PC. i-e microsoft excel
![Page 40: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/40.jpg)
Components of DSS
Analytical model Specialized database Decision maker’s own judgement An interactive, conputer base modeling
porcess to support the making of semistructured business decision.
![Page 41: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/41.jpg)
example
sales manager typically rely on the MIS to produce sales analysis reports. These reports contain sales perforance figures by product line, sales legion, and so on. a DSS, on the other hand, would also interactively show a sales manager the effect on sale perfomance of change in a verity of factors (promotional exp: & sales compensation.)
The DSS could the use several criteria( market sari & gross margined)to evaluate & rank alternative combination of sales performance factors.

Using DSS
WHAT – IF ANALYSIS Sensitivity Analysis Goal seeking Analysis Optimization Analysis
![Page 43: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/43.jpg)
What- if analysis
A user make changes to variables, or a relationship among the variables, & observes the resulting changes in the values of other variables.
![Page 44: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/44.jpg)
Seensitivity analysis
Observing how repeated changes to a single variable affect other variables. I-e lets cut advertising by $100 repeatedly so we can see its relationship to sale.
![Page 45: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/45.jpg)
Goal Seeking Analysis
Making repeated changes to selected variables until a chosen variable reaches a target value. Example: lets try increases in advertising until sales reach $1 million.
![Page 46: MIS presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558c2f29d8b42a553e8b45cf/html5/thumbnails/46.jpg)
Optimization analysis
Finding an optimum value for selected variables, given certain constraints. Examples: what is the best amount of advertising to have, given our budget & choice of media?
