Information is the basis for every decision taken in an organization. The efficiency of
management depends upon the availability of regular and relevant information. Thus it is
essential that an effective and efficient reporting system be developed as part of accounting
system. The main object of management information is to obtain the required about the
operating results of an organization regularly in order to use them for future planning and
control. The old techniques like intuition, rule of thumb, personal whim and prestige, etc.
are now considered useless in the process of decision taking. Modern management is
constantly on look out for such quantitative and such information, which can help in
analyzing the proposed alternative actions and choosing one as its decision. Thus, modern
management functions are information-oriented more popularly known as ―”management
by information”. And the system through which information is communicated to the
management is known as ―”management information system (MIS)”. The management
needs full information before taking any decision .good decisions can minimize costs and
optimize results. Management information system can be helpful to the management in
undertaking management decisions smoothly and effectively.

Management information system can be analyzed thus:
Information: information, in MIS, means the processed data that helps the management in
planning, controlling and operations. Data means all the facts arising out of the operations
of the concern. Data is processed i.e. recorded, summarized, compared and finally
presented to the management in the form of MIS report.
System: data is processed into information with the help of a system. a system is made up
of inputs, processing, output and feedback or control. Thus MIS means a system for
processing data in order to give proper information to the management for performing its
functions.
II. There are huge amount of information available to today’s manager and this had
therefore meant that managers are increasingly relying on management information
system to access the exploding information.
III. Management information services helps manager to access relevant, accurate, up-
to-date information which is the more sure way of making accurate decisions. It also
helps in automation and incorporation of research and management science
techniques into the overall management information system for example
probability theory.
IV. The management information services are capable of taking advantage of the
computational ability of the company like processing, storage capacity among
others.

Functional aspects
a. The organization that uses MIS is able to record, process, route & tabulate all
important business transactions. As & when need arises the organization is able to
incorporate the needed changes & improvements in the area of concern.
c. The top management ANALYSES whether its resources are being utilized optimally.
e. MIS supports the planning & controlling function of managers in the organization.
Managers use past/historical data as well as the current data to analyze the
performance & hence apply controlling measures.

g. It brings COORDINATION. It facilitates integration of specialized activities by
keeping each department aware of the problems & requirements of other
departments.
ii. In Minimizes information overload: MIS change the larger amount of data in to
summarize form and there by avoids the confusion which may arise when managers
are flooded with detailed facts.
v. It makes control easier: MIS serves as a link between managerial planning and
control. It improves the ability of management to evaluate and improve
performance. The used computers has increased the data processing and storage
capabilities and reduced the cost.
vi. Transaction processing :systems offer enterprises the means to rapidly process
transactions to ensure the smooth flow of data and the progression of processes
throughout the enterprise
vii. Rapid Processing: The rapid processing of transactions is vital to the success of any
enterprise – now more than ever, in the face of advancing technology and customer
demand for immediate action.
viii. Reliability: Similarly, customers will not tolerate mistakes. TPS systems must be
designed to ensure that not only do transactions never slip past the net, but that the
systems themselves remain operational permanently.
ix. MIS assembles, process, stores, Retrieves, evaluates and disseminates the
information.

Classification of MIS
Information systems are made out of components that can be assembled in many different
configurations, resulting in a variety of information systems and applications, much as
construction materials can be assembled to build different homes types. The size and cost
of a home depend on the purpose of the building, the availability of money, and constraints
such as ecological and environmental legal requirements. Just as there are many different
types of houses, so there are many different types of information systems. It is useful to
classify information systems into groups that share similar characteristics. Such a
classification may help in identifying systems, analyzing them, planning new systems,
planning integration of systems, and making decisions such as the possible outsourcing of
systems. This classification can be done in several alternative ways. Information systems
are classified by:
Organizations are made up of components such as divisions, departments, and work units,
organized in hierarchical levels. For example, most organizations have functional
departments, such as production and accounting, which report to plant management,
which report to a division head. The divisions report to the corporate headquarters.
Although some organizations have restructured themselves in innovative ways, such as
those based on cross-functional teams, today the vast majority of organizations still have a
traditional hierarchical structure. Thus, we can find information systems built for
headquarters, for divisions, for the functional departments, for operating units, and even
for individual employees. Such systems can stand alone, but usually they are
interconnected.
Typical information systems that follow the organizational structure are functional
(departmental), enterprise, and inter-organizational. These systems are organized in a
hierarchy in which each higher-level system consists of several (even many) systems from
the level below it. At a higher level, the enterprise system supports the entire company, and
inter-organizational systems connect different companies.

Classification by Mode of Data Processing
i. Batch Processing Systems: The transactions are collected as they occur, but
processed periodically, say, once a day or week.
ii. On-line Real-time Systems: The transaction data capture as well as their
processing in order to update records (and generate reports) is carried out in
real-time as the transaction is taking place.
ii. Process Control System (PCS): These systems are designed to make routine decision
that control operational processes.

iii. Decision Support Systems (DSS): Their objective is to support the managerial
decisions. Usually, these systems are based on a model of the decision-making domain,
and utilize techniques from management science, finance or other functional areas of
business in order to build such models. These systems are also used often for attention-
directing purposes, i.e., for directing the attention of managers to a problematic aspect
of operations.
iv. Expert Systems (ES): These systems incorporate expertise in order to aid managers in
diagnosing problems or in problem solving.
v. Executive Information System (EIS): These are MIS tailored to the strategic
information needs of the top managers.
vi. Business Information Systems (BIS): As a future managerial end user, it is very
important to realize that information systems directly support both operations and
management activities in business functions of accounting, finance, human resource
management, marketing, and operations management. Such business information
systems are needed by all business functions.

Classification based on type of support provided
Another way to classify information systems is according to the type of support they
provide, regardless of the functional area. For example, an information system can support
office workers in almost any functional area. Likewise, managers working from various
geographical locations can be supported by a computerized decision-making system.
Clerical workers, who support managers at all levels of the organization, include
bookkeepers, secretaries, electronic file clerks, and insurance claim processors. Lower-
level managers handle the day-to-day operations of the organization, making routine
decisions such as assigning tasks to employees and placing purchase orders. Middle
managers make tactical decisions, which deal with activities such as short-term planning,
organizing, and control.
10 Abhishek Chakraborty

Knowledge workers are professional employees such as financial and marketing
analysts, engineers, lawyers, and accountants. All knowledge workers are experts in a
particular subject area. They create information and knowledge, which they integrate into
the business. Knowledge workers act as advisors to middle managers and executives.
Finally, executives make decisions that deal with situations that can significantly
change the manner in which business is done. Examples of executive decisions are
introducing a new product line, acquiring other businesses, and relocating operations to a
foreign country.
Office automation systems (OAS's) typically support the clerical staff, lower and
middle managers, and knowledge workers. These employees use OAS to develop
documents (word processing and desktop publishing software), schedule resources
(electronic calendars), and communicate (e-mail, voice mail, videoconferencing, and
groupware).

Batch processing
There are a number of differences between real-time and batch processing. These are
outlined below:
Each transaction in real-time processing is unique. It is not part of a group of
transactions, even though those transactions are processed in the same manner.
Transactions in real-time processing are stand-alone both in the entry to the system
and also in the handling of output.
Real-time processing requires the master file to be available more often for updating
and reference than batch processing. The database is not accessible all of the time
for batch processing.
Real-time processing has fewer errors than batch processing, as transaction data is
validated and entered immediately. With batch processing, the data is organized and
stored before the master file is updated. Errors can occur during these steps.
Infrequent errors may occur in real-time processing; however, they are often
tolerated. It is not practical to shut down the system for infrequent errors. More
computer operators are required in real-time processing, as the operations are not
centralized. It is more difficult to maintain a real-time processing system than a
batch processing system.
Example
• Reservation systems: set aside service/product for future use
• Motels
• Point-of-sale (POS) terminals: sells goods/services
• Library loan systems: keeps track of items borrowed from library.
Features

Rapid response - Fast performance with a rapid response time is critical.
Businesses cannot afford to have customers waiting for a TPS to respond, the
turnaround time from the input of the transaction to the production for the output
must be a few seconds or less. Reliability- Many organizations rely heavily on their
TPS; a breakdown will disrupt operations or even stop the business. For a TPS to be
effective its failure rate must be very low. If a TPS does fail, then quick and accurate
recovery must be possible. This makes well–designed backup and recovery
procedures essential.

The term office automation refers to all tools and methods that are applied to office
activities which make it possible to process written, visual, and sound data in a computer-
aided manner. Office automation is intended to provide elements which make it possible to
simplify, improve, and automate the organisation of the activities of a company or a group
of people (management of administrative data, synchronization of meetings, etc.).
Considering that company organizations require increased communication, today, office
automation is no longer limited to simply capturing handwritten notes. In particular, it also
includes the following activities:
exchange of information
management of administrative documents
handling of numerical data
meeting planning and management of work schedules

At the heart of these systems is often a local area network (LAN). The LAN allows users to
transmit data, voice, mail, and images across the network to any destination, whether that
destination is in the local office on the LAN, or in another country or continent, through a
connecting network. An OAS makes office work more efficient and increases productivity.
Electronic Mail- E-mail is software that allows users, via their computer keyboards,
to create, send, and receive messages and files to or from anywhere in the world.
Most email systems let the user do other sophisticated tasks such as filter, prioritize,
or file messages; forward copies of messages to other users; create and save drafts
of messages; send "carbon copies"; and request automatic confirmation of the
delivery of a message. E-mail is very popular because it is easy to use, offers fast
delivery, and is inexpensive. Examples of e-mail software are Eudora, Lotus Notes,
and Microsoft Outlook.

of microcomputers to share information, update schedules and plans, and cooperate
on projects regardless of geographic distance. Special software called groupware is
needed to allow two or more people to edit or otherwise work on the same files
simultaneously.

Telecommuters perform some or all of their work at home instead of traveling to an
office each day, usually with the aid of office automation systems, including those
that allow collaborative work or meetings. A microcomputer, a modem, software
that allows the sending and receiving of work, and an ordinary telephone line are
the tools that make this possible.
At some conference halls, like this one at the Chinzan-so Four Seasons Hotel in
Toyko, small video screens are built into the table tops.
Studies have found that telecommuting programs can boost employee morale and
productivity among those who work from home. It is necessary to maintain a
collaborative work environment, however, through the use of technology and
general employee management practices, so that neither on-site employees nor
telecommuters find their productivity is compromised by such arrangements. The
technologies used in electronic communication and teleconferencing can be useful
in maintaining a successful telecommuting program.

Image Processing- Image processing systems include electronic document
management, presentation graphics, and multimedia systems. Imaging systems
convert text, drawings, and photographs into digital form that can be stored in a
computer system. This digital form can be manipulated, stored, printed, or sent via a
modem to another computer.
Imaging systems may use scanners, digital cameras, video capture cards, or
advanced graphic computers. Companies use imaging systems for a variety of
documents such as insurance forms, medical records, dental records, and mortgage
applications.
Presentation graphics software uses graphics and data from other software tools
to create and display presentations. The graphics include charts, bullet lists, text,
sound, photos, animation, and video clips. Examples of such software are Microsoft
Power Point, Lotus Freelance Graphics, and SPC Harvard Graphics.
Multimedia systems are technologies that integrate two or more types of media
such as text, graphic, sound, voice, full-motion video, or animation into a computer-
based application. Multimedia is used for electronic books and newspapers, video
conferencing, imaging, presentations, and web sites.

The exact reporting tools and outcome of an Executive Support System completely depends
on the ESS developer and it's intended industry use. For example, Cambridge Systematics
has ESS to support the investment planning process for the Ministry of Transportation. The
features and functions of this Executive Support System are entirely different from the
Executive Support System developed by Meditech, which is useful to health care
organizations.
Several companies offer pre-designed Executive Support System packages (usually suited
to one particular industry), while others offer packages which can be customized your
organization's needs.
For most businesses, there are a variety of requirements for information. Senior managers
need information to help with their business planning. Middle management need more
detailed information to help them monitor and control business activities. Employees with
operational roles need information to help them carry out their duties. As a result,
businesses tend to have several "information systems" operating at the same time. This
revision note highlights the main categories of information system and provides some
examples to help you distinguish between them.
The main kinds of information systems in business are described briefly below:

Transaction Processing Systems: As the name implies, Transaction Processing
Systems ("TPS") are designed to process routine transactions efficiently and
accurately. A business will have several (sometimes many) TPS; for example:
- Billing systems to send invoices to customers - Systems to calculate the weekly and
monthly payroll and tax payments
- Production and purchasing systems to calculate raw material requirements
- Stock control systems to process all movements into, within and out of the
business.
Office Automation Systems: Office Automation Systems are systems that try to
improve the productivity of employees who need to process data and information.
Perhaps the best example is the wide range of software systems that exist to
improve the productivity of employees working in an office (e.g. Microsoft Office XP)
or systems that allow employees to work from home or whilst on the move.

Artificial intelligence (AI) is the effort to develop computer-based systems (both hardware
and software) that behave as humans, with the ability to learn languages, accomplish
physical tasks, use a perceptual apparatus, and emulate human expertise and decision
making .
Intelligent agents: Are software programs that work in the background without direct
human intervention Carry out specific, repetitive, and predictable tasks. Use a limited built-
in or learned knowledge base to accomplish tasks or make decisions on the user's behalf
are used in agent-based modeling applications used to model or simulate the behavior of
consumers, stock markets, and supply chains.
