MIS (Management Information System) Tutorial
Training Summary
Management
Information System (MIS) is a computer-based system that collectively provides
managers with the information required to organize, manage and analyze the ongoing
project operations. In this course, we will cover important MIS topics like
roles of MIS in an organization, technologies used in MIS, types of MIS, etc.
What is MIS? Intoduction & Definition
What is MIS?
MIS is the use of information technology, people, and business
processes to record, store and process data to produce information that
decision makers can use to make day to day decisions.
MIS is the acronym for Management Information Systems. In
a nutshell, MIS is a collection of systems, hardware, procedures and people
that all work together to process, store, and produce information that is
useful to the organization.
The need for MIS
The following are some of the justifications for having an MIS
system
- Decision
makers need information to make effective decisions. Management
Information Systems (MIS) make this possible.
- MIS
systems facilitate communication within and outside the organization
employees within the organization are able to easily access the required
information for the day to day operations. Facilitates such as Short
Message Service (SMS) & Email make it possible to communicate with
customers and suppliers from within the MIS system that an organization is
using.
- Record
keeping management information systems record all
business transactions of an organization and provide a reference point for
the transactions.
Components of MIS
The major components of a typical management information system
are;
- People people
who use the information system
- Data the
data that the information system records
- Business Procedures procedures
put in place on how to record, store and analyze data
- Hardware these
include servers, workstations, networking equipment, printers, etc.
- Software these
are programs used to handle the data. These include programs such as
spreadsheet programs, database software, etc.
Types of Information Systems
The type of information system that a user uses depends on their
level in an organization. The following diagram shows the three major levels of
users in an organization and the type of information system that they use.
Transaction Processing Systems (TPS)
This type of information system is used to record the day to day
transactions of a business. An example of a Transaction Processing System is a
Point of Sale (POS) system. A POS system is used to record the daily sales.
Management Information Systems (MIS)
Management Information Systems are used to guide tactic managers
to make semi-structured decisions. The output from the transaction processing
system is used as input to the MIS system.
Decision Support Systems (DSS)
Decision support systems are used by top level managers to make
semi-structured decisions. The output from the Management Information System is
used as input to the decision support system.DSS systems also get data input
from external sources such as current market forces, competition, etc.
Manual Information Systems VS Computerized Information Systems
(MIS)
Data is the bloodstream of any business entity. Everyone in an organization
needs information to make decisions. An information system is an organized way
of recording, storing data, and retrieving information.
In this section, we will look at manual information systems vs.
computerized information systems.
Manual Information System
A manual information system does not use any computerized
devices. The recording, storing and retrieving of data is done manually by the
people, who are responsible for the information system.
The following are the major components of a manual information
system
- People
people are the recipients of information system
- Business
Procedures these are measures put in place that define
the rules for processing data, storing it, analyzing it and producing
information
- Data
these are the recorded day to day transactions
- Filing
system this is an organized way of storing
information
- Reports
the reports are generated after manually analyzing the
data from the filing system and compiling it.
The following diagram illustrates how a typical manual
information system works
Advantages and Dis-advantages of a manual information system
Advantages:
The following are the advantages of manual information systems
- Cost
effective it is cheaper compared to a
computerized system because there is no need to purchase expensive
equipment such as servers, workstations, printers, etc.
- Flexible
evolving business requirements can easily be
implemented into the business procedures and implemented immediately
Disadvantages:
The following are some of the disadvantages of a manual
information system.
- Time consuming all data entries need to
be verified before filing, this is a time consuming task when done by
humans. Retrieving data from the filing system also takes a considerable
amount of time
- Prone to error the accuracy of the
data when verified and validated by human beings is more prone to errors
compared to verification and validation done by computerized systems.
- Lack of security the security of
manual systems is implemented by restricting access to the file room.
Experience shows unauthorized people can easily gain access to the filing
room
- Duplication of data most departments in
an organization need to have access to the same data. In a manual system,
it is common to duplicate this data to make it easy to accessible to all
authorized users. The challenge comes in when the same data needs to be
updated
- Data inconsistency due
to the duplication of data, it is very common to update data in one file
and not update the other files. This leads to data inconsistency
- Lack of backups if the file get
lost or mishandled, the chances of recovering the data are almost zero.
Computerized information system
Computerized systems were developed to address the challenges of
manual information systems. The major difference between a manual and
computerized information system is a computerized system uses a combination of
software and hardware to record, store, analyze and retrieve information.
Advantages and Disadvantages of a computerized information
system (MIS)
The following are some of the disadvantages of a computerized
information system.
Advantages:
The following are the advantages of computerized information
systems
- Fast
data processing and information retrieval this
is one of the biggest advantages of a computerized information system. It
processes data and retrieves information at a faster rate. This leads to
improved client/customer service
- Improved
data accuracy easy to implement data validation and
verification checks in a computerized system compared to a manual system.
- Improved
security in addition to restricting access to the
database server, the computerized information system can implement other
security controls such as users authentication, biometric authentication
systems, access rights control, etc.
- Reduced
data duplication database systems are
designed in such a way that minimized duplication of data. This means
updating data in one department automatically makes it available to the
other departments
- Improved
backup systems with modern day technology, backups
can be stored in the cloud which makes it easy to recover the data if
something happened to the hardware and software used to store the data
- Easy
access to information most business executives
need to travel and still be able to make a decision based on the
information. The web and Mobile technologies
make accessing data from anywhere possible.
Disadvantages:
- It
is expensive to set up and configure the
organization has to buy hardware and the required software to run the
information system. In addition to that, business procedures will need to
be revised, and the staff will need to be trained on how to use the
computerized information system.
- Heavy
reliance on technology if something happens to
the hardware or software that makes it stop functioning, then the
information cannot be accessed until the required hardware or software has
been replaced.
- Risk
of fraud if proper controls and checks are not in
place, an intruder can post unauthorized transactions such as an invoice
for goods that were never delivered, etc.
Summary
- MIS
is the acronym for Management Information System. It is a collection of people,
procedures, data, and information technology that aids managers to make
informed decisions.
- Computerized
information systems are more efficient compared to manual information
systems. Manual information systems are cheaper compared to computerized information
systems.
- Transaction
processing systems (TPS) are by operational staff to record day to day
business transactions, and they are used to make structured decisions
- Management
Information Systems (MIS) are used by middle-level managers to make semi-structured
decisions
- Decision
Support Systems are used by top level managers, and they help top level
managers to make unstructured decisions.
