Introduction
• Information system (IS)– Set of interrelated components: collect, manipulate,
disseminate data and information– Provide feedback to meet an objective– Examples: ATMs, airline reservation systems, course
reservation systems
What is Information, really? Why have it?

Information Concepts: Data Versus Information
• Data: raw facts– Alphanumeric, image, audio, and video
• Information– Organized collection of facts– Have value beyond the facts themselves
data or other informationcomponents themselves
Recordings of machines’ experiences
Information is “information” only to the extent that it informs a user or consumer. That
means that the informationness of an experience depends on the observer and what
the observer has to do (intention)!

What Is an Information System?
Figure 1.3: The Components of an Information System
This is only one view. A system is much more complex. A behavioral view will
keep in mind intentions, skills, judgments, and prior knowledge (theory)
MIS 300 Chapter 1 19
Computer-Based Information Systems
• Manual versus computerized information systems• Computers are NOT necessary in information
systems, but they have certain efficiencies • Computer-based information system (CBIS)
– Hardware, software, databases, telecommunications, people, and procedures
– Collect, manipulate, store, and process data into information

Business Information Systems
• Most common types of information systems used in business organizations:– Electronic and mobile commerce systems – Transaction processing systems – Management information systems – Decision support systems – Specialized business information systems These are detailed next.
MIS 300 Chapter 1 22
Electronic and Mobile Commerce
• E-commerce: any business transaction executed electronically between parties such as:– Companies (B2B)– Companies and consumers (B2C)– Consumers and other consumers (C2C)– Business and the public sector– Consumers and the public sector
MIS 300 Chapter 1 23
Transaction Processing Systems
• Transaction: business-related exchange– Payments to employees– Sales to customers– Payments to suppliers
• Transaction processing system (TPS)– A collection of people, procedures, software,
databases, devices– Records completed business transactions
MIS 300 Chapter 1 24
Transaction Processing Systems (continued)
Figure 1.7: A Payroll Transaction Processing SystemThe inputs (numbers of employee hours worked and pay rates)
go through a transformation process to produce outputs (paychecks)
MIS 300 Chapter 1 25
Enterprise Resource Planning
• Integrated programs that manage all business operations
• Coordinate planning, inventory control, production, and ordering among others
• Historically based in production systems• Hard to translate to other types of business• Necessarily complex
MIS 300 Chapter 1 26
Management Information Systems
• Management information system (MIS)– A collection of people, procedures, software,
databases, devices– Provides information to managers/decision makers
• Primary focus is operational efficiency• MIS outputs
– Scheduled reports– Demand reports– Exception reports
MIS 300 Chapter 1 27
Management Information Systems (continued)
Figure 1.8: Functional management information systems draw data from the organization’s transaction processing system
MIS 300 Chapter 1 28
Decision Support Systems
• Decision support system (DSS)– A collection of people, procedures, software,
databases, devices– Supports problem-specific decision making
• Focus is on decision-making effectiveness
MIS 300 Chapter 1 29
Decision Support Systems (continued)
Figure 1.9: Essential DSS Elements
MIS 300 Chapter 1 30
Systems Development
• Systems development– Creating or modifying existing business systems
• Systems investigation: gain an understanding • of the problem to be solved or opportunity to be
addressed• Systems analysis: define problems and
opportunities of the existing system
MIS 300 Chapter 1 31
Systems Development (continued)
• Systems design: determine how the new system will work to meet the business needs defined during systems analysis
• Systems implementation: create or acquire the various system components defined in the design step, assembling them, and putting the new system into operation
• Systems maintenance and review: check and modify the system so that it continues to meet changing business needs
MIS 300 Chapter 1 32
Organizations and Information Systems
• Organization: a collection of people and other resources established to accomplish a set of goals
• An organization is a system– Inputs: resources (materials, people, money)– Outputs: goods or services
MIS 300 Chapter 1 33
Organizations and Information Systems (continued)

MIS 300 Chapter 1 34
Organizations and Information Systems (continued)
• Value chain: a series (chain) of activities that includes inbound logistics, warehouse and storage, production, finished product storage, outbound logistics, marketing and sales, and customer service
• Upstream management: management of raw materials, inbound logistics, and warehouse and storage facilities
• Downstream management: management of finished product storage, outbound logistics, marketing and sales, and customer service

Organizations in a Global Society
• As companies rely on virtual structures and outsourcing to a greater extent, businesses can operate around the world
• Challenges to operating in a global society– Every country has a set of customs, cultures,
standards, politics, and laws– Language barriers– Difficulty in managing and controlling operations in
different countries
