What Is Management

Management the process of coordinating work activities

so that they are completed efficiently and effectively with and through other peopleProcess - represents ongoing functions or

primary activities engaged in by managersCoordinating - distinguishes a managerial

position from a non-managerial one

Page 3: Management information system-MIS

What is Management

Management (cont.) Efficiency - getting the most output from the least

amount of inputs “doing things right” (not wasting resources) concerned with means Examples: cutting inventory levels Decreasing the amount of time to manufacture

products Effectiveness - completing activities so that

organizational goals are attained “doing the right things” concerned with ends

Key Resources of MIS Information

DataAre raw facts that describe a particular phenomenone.g Current Temperature, Price of property, Age of a person etc.

A message which source wants to communicate to the receivere.g Text, Voice, Image, movies, Music etc

Information: Data that is organized, meaningful, and useful

data with context processed data value-added to data

summarized organized analyzed

Data and InformationData and Information

Page 7: Management information system-MIS

Changing Data into Information

• Data – Raw facts stored in databases– Need additional processing to become useful

• Information– Required by decision maker – Data processed and presented in a meaningful form– Transformation (any process that changes data into information).

4. Organized.

5. Meaningful.

6. Cost effective.

Page 11: Management information system-MIS

1.Accuracy

• The information a user receives has been processed correctly

• Correct information

• Free from errors

• Inaccurate information can lead to incorrect decisions

Page 12: Management information system-MIS

2. Verifiable

User can confirm and verify the information.

Identify source of information

Page 13: Management information system-MIS

Having information when users need it.

Right information must be produced to users at right time.

3.Timely Information

Page 14: Management information system-MIS

4. Organized

Information is arranged to suit the needs and

requirements of the users.

Page 15: Management information system-MIS

5. Meaningful Relevant to the user who

receives or uses it.

Unnecessary information must be eliminated.

Page 16: Management information system-MIS

6.Cost-effective

The cost to produce the information should be less than the

actual cost of the information.

Page 17: Management information system-MIS

What is a System? A system is…

A set of interrelated components With a clearly defined boundary Working together To achieve a common set of objectives By accepting inputs and producing

outputs In an organized transformation process

Page 18: Management information system-MIS

Basic Functions of a System

Input: Capturing and assembling elements that enter the system to be

processed

Processing:

Transformation process that converts input into output

Output:

Transferring transformed elements to their ultimate destination

Page 19: Management information system-MIS

IT and IS• What is Information Technology?

Any form of technology used by people to handle information.

• What are Information Systems?“A collection of hardware, software, data, people, and procedures that are designed to generate information that support day-to-day

activities of users in an organization”

Page 20: Management information system-MIS

The branch of Engineering that deals with the use of Computers and Telecommunications to retrieve, store and transmit information

Any computer based tool that people use to work with information & support the information & information processing needs of an organization

Information Technology (IT)

Page 21: Management information system-MIS

Definition of Information Systems

“A collection of hardware, software, data, people, and procedures that

are designed to generate information that support day-to-

day activities of users in an organization”

Page 22: Management information system-MIS

Components of Information Systems

• Data

• Software

• Hardware

• People

• Procedures

Page 23: Management information system-MIS

Information System Activities

Input of data resources Data entry activities

Processing of data into information Calculations, comparisons, sorting, and so on

Output of information products Messages, reports, forms, graphic images

Storage of data resources Data elements and databases

Control of system performance Monitoring and evaluating feedback

Page 24: Management information system-MIS

Types of Information Systems

Operations Support Systems: TPS( Sales, Inventory, and accounting systems) PCS( Monitor and control industrial processes ( Petroleum refining,

power generation and steel production systems. Enterprise collaboration systems, such as e-mail, chat and

videoconferencing systems.

Management Support Systems: MIS( Provide information as reports and displays) DSS(such as products pricing, profitability forecasting, and risk

analysis. EIS( Provides critical information from MIS, DSS such as system for

easy access to analysis of business performance, action of competitors, and strategic planning

Page 25: Management information system-MIS

Types of Operations Support Systems

Transaction Processing Systems Record and process business transactions Examples: sales processing, inventory systems,

accounting systems Process Control Systems

Monitor and control physical processes Example: using sensors to monitor chemical processes

in a petroleum refinery Enterprise Collaboration Systems

Enhance team and workgroup communication Examples: email, video conferencing

Page 26: Management information system-MIS

Transaction Processing Systems

TPS is the important examples of Operations support systems that record and process data resulting from business transactions.

Computerized systems that perform and record the daily routine transactions necessary to conduct the business; they serve the organization’s operational level

Examples Accounting information systems TCS, DHL, all have systems that are TPS

Page 27: Management information system-MIS

Two Ways to Process Transactions

Batch Processing:

Accumulate transactions over time and process periodically

Example: a bank processes all checks received in a batch at night

Online Processing:

Process transactions immediately Example: a bank processes an ATM withdrawal

immediately

Page 28: Management information system-MIS

Example of TPS

1. An inventory control system keeps a file of records about the stock of goods that a business has on hand (the inventory) which is one aspect of the state of the business.

2. When items are shipped or received, the state of the business

is affected, and the inventory control system makes changes about the inventory in the stored records.

 

 

 

 

 

 

 

 

 

Page 29: Management information system-MIS

4. It also prints a report giving the quantity on hand for each item in inventory, which is a characteristic of the state of the business.

Finally, when inventory is low, the system produces output that causes more inventory to be ordered, which is another type of business transaction.

Example of TPS

Transaction Processing System Functions

Input function

• Capture input data• Enter input data• Validate input data

Processing function:

• perform computation• make decision

Output function:

• produce screen output• print output

Storage function:

• stored data• Access data• Update data

Page 32: Management information system-MIS

Transaction processing systems perform input, output, storage, and processing functions.

Input functions include capturing data on a source document, entering the input data into the system, and checking input data for errors, a process called data validation

Output functions include producing screen or paper reports, such as detail reports, summary reports, and exception reports.

Transaction Processing System

Page 33: Management information system-MIS

Storage functions include storing data in files and databases, accessing stored data, sorting stored data, and updating stored data.

Processing functions involve the manipulation of data, including computation and decision making

Management Information Systems

• MIS provides information in the form of reports and displays to managers and many business professionals. Such as sales analysis, production performance.

• Provides information to business professionals in a variety of easy-to-use formats.

• Examples– Systems that provide managers with reports and online real-

time access to company performance and historical records.

Page 37: Management information system-MIS

Decision Support Systems

Decision Support Systems are concerned with providing useful information to support the decision process.

A Production Manager may use a DSS to decides how much product to manufacture based on the expected sales associated with a future promotion and the location and availability of the raw materials necessary to manufacture the product.

• Examples– May take data from both internal sources (TPS, MIS) but also from external

sources (Stock prices or product prices of competitors)

– Shipping companies use voyage-estimating systems that take various shipping information into account and give advice on costs, freight rates for various types of cargo and port expenses etc
