Introduction to Information Systems
- An information system (IS) is a set of interrelated components that collect, manipulate, and disseminate data and provide feedback to meet an objective.
- Businesses can use information systems to increase revenues and reduce costs.
Information Concepts
- Information is one of an organization's most valuable resources and is often confused with the term data.
- Data refers to raw facts, while information is a collection of facts organized in a way that has value beyond the facts themselves.
Data, Information, and Knowledge
- Knowledge refers to the awareness and understanding of a set of information.
- Process refers to a set of logically related tasks.
The Characteristics of Valuable Information

- The importance of different characteristics of information depends on the type of data needed.
What is an Information System?
- An information system is a set of interrelated elements that collect, manipulate, store, disseminate data and information, and provide a corrective reaction (feedback mechanism) to meet an objective.
- The components of an information system include input, processing, output, and feedback.
Input, Processing, Output, Feedback
- Input refers to the activity of gathering and capturing raw data.
- Processing involves converting data into useful outputs.
- Output refers to the production of useful information, usually in the form of documents and reports.
- Feedback is information from the system that is used to make changes to input or processing activities.
Manual and Computerized Information Systems
- Information systems can be manual or computerized.
- Manual information systems involve manual data collection and processing, while computerized information systems use technology to perform these tasks.
Computer-Based Information Systems
- A computer-based information system is a single set of hardware, software, databases, telecommunications, people, and procedures that are configured to collect, manipulate, store, and process data into information.
- The technology infrastructure includes all hardware, software, databases, telecommunications, people, and procedures that are configured to collect, manipulate, store, and process data into information.
Components of Computer-Based Information Systems
- Hardware consists of computer equipment used to perform input, processing, and output activities.
- Software consists of the computer programs that govern the operation of the computer.
- Database is an organized collection of facts and information, typically consisting of two or more related data files.
- Telecommunications, networks, and the Internet refer to the electronic transmission of signals for communication, connecting computers and equipment to enable electronic communication, and the world's largest computer network, respectively.
- People are the most important element in most computer-based information systems, and procedures include strategies, policies, methods, and rules for using the CBIS.
Business Information Systems
- Most common types of information systems are designed for electronic and mobile commerce, transaction processing, management information, and decision support.
- Some organizations employ special-purpose systems, such as virtual reality, that not every organization uses.
Organizations and Information Systems
- An organization is a formal collection of people and other resources established to accomplish a set of goals.
- Value chain refers to a series of activities that includes inbound logistics and warehouse and storage.
- Supply chain management (SCM) determines what supplies are required, what quantities are needed, how supplies should be processed, and how shipment should be scheduled, monitored, and controlled.
Risk
- Managers must consider the risks of designing, developing, and implementing systems, as information systems can sometimes be costly failures.
Careers in Information Systems
- Degree programs in information systems, computer information systems, and management information systems are available.
- Primary responsibilities in information systems include operations, systems development, support, and information service units.
Roles, Functions, and Careers in IS
- Chief information officer (CIO) employs the IS department's equipment and personnel to help the organization attain its goals.
- Other roles include LAN administrators, Internet strategists, Internet systems developers, Internet programmers, and Internet or Web site operators.
Working in Teams
- It is essential for IS professionals to have good communication skills and the ability to work with other people.
- Getting the best team of IS personnel to work on important projects is critical in successfully developing new information systems or modifying existing ones.
