1. MIS(Management Information System)
![Page 11: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/11.jpg)
Definition of MIS
MIS is an integrated ,user-machine system for providing information to support operations , management and decision making function of an organization.The system utilizes computer hardware and software ; manual procedure ;models for analysis ,planning , control and decision making ;and a database
![Page 12: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/12.jpg)
Thus, MIS is • An integrated user-machine system• For providing information• Supports the operations , management , analysis
and decision making functionsSystem utilizes• Computer hardware and software• Manual procedure• Models for analysis , planning, control , decision
making• A database
![Page 13: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/13.jpg)
SIMPLY MIS IS;
MIS is that system in which raw data is collected and analyses it . After making it useful , it is used for decision making
purpose
![Page 14: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/14.jpg)
Meaning
•Management practical use of power of Decision making• Information processed and useful data•System technique of use of data for business
![Page 15: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/15.jpg)
Management
Management is the activity of getting things done with the aid of people and other resources.
![Page 16: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/16.jpg)
•No business in the world has ever made more money with poorer management
![Page 17: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/17.jpg)
INFORMATION
• Processed data•Useful for decision making•Organized form of data•Vital ingredient for the operations and
management
![Page 18: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/18.jpg)
SYSTEM
A system is a group of elements that are
integrated with the common purpose of achieving objective
![Page 19: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/19.jpg)
An example
• Raju bought a new computer system in which lot of peripherals attached to achieve a common objective
![Page 20: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/20.jpg)

INFORMATION SYSTEM• System consisting of network of all
communication channels used within an organization•A combination of hardware, software,
instructions and trained personnel organized to facilitate planning , control , decision making in an organization
![Page 22: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/22.jpg)
SYSTEM MAY BE ;
•ABSTARCT
Or
• PHYSICAL
![Page 23: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/23.jpg)
Abstract system
Orderly arrangement of interdependent ideas or constructs eg: System of Theology
![Page 24: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/24.jpg)
Physical system
Comprises a set of elements which operate together to accomplish an objective eg: computer system Accounting system etc..
![Page 25: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/25.jpg)
System approach to Management(simple system model)System in simple terms in respect to management ,it is a set of different independent parts working together in interrelated manner to accomplish a set of objective
![Page 26: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/26.jpg)
Simple System Model
OutputsProducts and
services Financial results
Transformation processEmployees work activities
Management activities
InputsRaw material Human resources
![Page 27: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/27.jpg)
Interfaces
• The interconnections and interactions between the subsystem • Interface occurs at the boundary and takes
the forms of inputs and outputs eg. An user interface in a computer system
![Page 28: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/28.jpg)
Types of system
•Deterministic and Probabilistic System• Closed and Open System•Human and Machine’s System
![Page 29: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/29.jpg)
Deterministic and Probabilistic system
Deterministic System•Operates in a predictable manner•The interaction among the part is known with certainty
Eg: Correct computer programme which performs exactly according to a set of instructions
![Page 30: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/30.jpg)
Probabilistic System
Probable behavior
Error prone Eg: Working of an Inventory System Set of instruction given to a Human Being
![Page 31: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/31.jpg)
Closed and Open SystemClosed systemSelf contained and isolated from its environment• It is a non-Adaptive system• Doesn’t receive inputs from
other systems Eg: An automated wrist watch A predefined computer programme
![Page 32: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/32.jpg)
Open systems
• Exchange information material or energy with the environment
• By interacting with other system it establishes exchange relationships
Eg: All organizations
![Page 33: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/33.jpg)
Can you Answer??“Organizations are open system “ WHY?
![Page 34: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/34.jpg)
Organization as an open system•Organizations receives unplanned and
unscheduled inputs from there environment
• Organizations are capable of adapting in the phase of changing competition
![Page 35: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/35.jpg)
Human and Machine SystemsHuman System • Combination of different
subsystems • Interrelated to achieve a common goal
Eg: Respiratory system Digestion system Nerve system
![Page 36: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/36.jpg)
Machine system
• Includes lot of subsystems
• Interrelated and interdependent components
•Mainly works to achieve a common goalEg: Computer system
![Page 37: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/37.jpg)
• Information System are generally human- machine system in that both performs some of the activities in the accomplishment of a goal
Eg: Making a decision
![Page 38: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/38.jpg)
subsystems
• Building blocks of development of systems• Subsystems are interrelated and interdependent• Works together in order to achieve common
goal E.g. : Peripherals attached to a computer system : Different functional areas of management
![Page 39: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/39.jpg)
Decomposition•A system as a whole , is a complex•A system should decomposed or factored
in different subsystems • Some of the subsystem constitutes the
entire systems•Division of whole systems into
manageable subsystems • It makes hierarchy•One subsystem is a element of
Suprasystem
![Page 40: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/40.jpg)
Eg: Information system divided into subsystems
1. Sales and order entity2. Inventory3. Production4. Personnel & Payroll5. Purchasing6. Planning
![Page 41: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/41.jpg)
Simplification
• Process of Organizing subsystems so as to reduce the number of interconnections
The no . of interconnections=
1/2n(n-1) where n=no . of subsystems
![Page 42: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/42.jpg)
Organizational Efficiency and Effectiveness• Effectiveness is a measure of goodness of output• Efficiency is a measure of the resource required
to achieve the output• The organizations tempt to measure and control
efficiency more than effectiveness
• Eg: A public school Measures performance by cost per credit hour(efficiency) but doesn’t measure the effect of the credit hours on the student
![Page 43: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/43.jpg)
Information system as a system• It receives inputs of data and instructions ,
process the data according to the instructions and output the results•Data storage therefore added to this system Eg: Hardware& system storage Management& administration system
Applications systems etc..
![Page 44: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/44.jpg)
Project Management• System concept is relative to the project
developing and control• Subsystems should be assigned to different
members of a project team• A project planning and control system monitors
each subsystems• Planning and control are guided by system
objectives• Performance for the project is measured by
overall system performance rather than by the performance of the separate systems
![Page 45: Mis seminar1](https://reader036.fdocuments.es/reader036/viewer/2022062503/58edbbee1a28abf0458b45eb/html5/thumbnails/45.jpg)
At a glance (Part 1)• Concepts of MIS , Systems and organizations are
particularly relevant to the information system design• A system consists of elements which operate
together to accomplish an objective• Basic model of system• Systems can be deterministic , probabilistic or
open or closed• An information system is a human – machine
systems• Decomposition of system into subsystem • The system approach is especially relevant to
information system
