Study Notes
Introduction to Information Systems
- An information system (IS) is a collection of interconnected components designed to gather, process, and distribute data and information to achieve a specific objective.
- Information systems help organizations achieve their goals, increase revenue, and reduce costs by providing valuable feedback.
Information Concepts
- Information is one of the most valuable assets an organization possesses.
- It's often confused with data, but information is derived from data.
Data, Information, and Knowledge
- Data represents raw facts, while information is organized data with value beyond the facts themselves.
- Processes are sets of logical tasks designed to achieve a specific outcome.
- Knowledge is the understanding of information and its effective application to support tasks.
Characteristics of Valuable Information
- Accuracy and completeness are crucial as inaccurate or incomplete information leads to poor decisions and financial losses.
- The importance of different characteristics, such as timeliness, relevance, and accessibility, varies depending on the specific data needs.
System Concepts
- A system is a collection of interacting elements or components working towards a common goal.
- Systems consist of inputs, processing mechanisms, outputs, and feedback loops.
System Performance and Standards
- Efficiency measures the ratio of what is produced to what is consumed.
- Effectiveness measures how well a system achieves its goals.
- System performance standards are specific objectives for the system, such as achieving a certain level of accuracy or speed.
Information Systems & Their Core Components
- Information System (IS): A system that collects, manipulates, stores, disseminates data, and provides feedback to meet objectives.
- Input: Involves gathering and capturing raw data.
- Processing: Transforming data into useful outputs.
- Output: Producing information, often in the form of documents and reports.
- Feedback: Information from the system used to modify input or processing activities.
Computer-Based Information Systems (CBIS)
- CBIS: A single set of hardware, software, databases, telecommunications, people, and procedures that collect, manipulate, store, and process data into information.
- Technology Infrastructure: Hardware, software, databases, telecommunications, people, and procedures - forms the foundation of each CBIS.
- Hardware: Consists of computer equipment: input, processing, storage, output.
- Software: Computer programs controlling the operation of the computer.
- Database: An organized collection of facts and information (typically two or more related data files).
- Telecommunications: The electronic transmission of signals for communication.
- Networks: Connect computers and equipment for electronic communication.
- Internet: The world's largest computer network connecting thousands of interconnected networks.
- Web: A network of links on the Internet containing text, graphics, video, and sound.
- Intranet: An internal network for information exchange and project collaboration within an organization.
- Extranet: A network using Web technologies to allow authorized outsiders (business partners, customers) to access authorized resources of a company’s intranet.
- People: Consider the most important element in most CBIS.
- Procedures: Strategies, policies, methods, and rules for using the CBIS.
Common Business Information Systems
- Electronic and Mobile Commerce (E-commerce) covers business transactions executed electronically between companies, individuals, and public entities.
- Mobile commerce (m-commerce): Transactions conducted using mobile, wireless devices.
- E-procurement: Acquiring parts and supplies through information systems and the internet.
- Electronic business (e-business): Uses information systems and the Internet for all business-related tasks and functions.
- Enterprise Systems: Transaction Processing Systems (TPS) and Enterprise Resource Planning (ERP).
- Transaction: Any business-related exchange (like payments to employees, sales to customers).
- TPS: A system that records and performs completed business transactions using people, procedures, software, databases, and devices.
- ERP: A set of integrated programs that manage vital business operations for a multi-site, global organization.
- Management Information System (MIS): Provides routine information for managers and decision-makers, with a focus on operational efficiency.
- Decision Support System (DSS): Assists problem-specific decision making, focusing on effectiveness. Used when information is complex and hard to obtain.
Specialized Business Information Systems
- Knowledge Management Systems (KMSs): Create, store, share, and use organizational knowledge and experience.
- Artificial Intelligence (AI): Computer systems exhibiting characteristics of human intelligence. Includes:
- Robotics: Machines handle complex, dangerous or routine tasks.
- Vision Systems: Allow devices to see, store, and process images.
- Natural Language Processing: Computers understanding and acting on verbal or written commands.
- Learning Systems: Learning from past mistakes or experiences.
- Neural Networks: Recognizing and acting on patterns or trends.
- Expert Systems: Provide computer-based expert advice in specific fields, using a knowledge base of data, rules, procedures, and relationships.
Systems Development:
- Systems development: Creating or modifying business systems.
- Outsourcing: Companies focus on core areas by delegating other functions, including systems development, to specialized companies.
Systems Development Stages:
- Systems Investigation: Understanding the problem or opportunity to be addressed.
- Systems Analysis: Defines problems and opportunities of the existing system.
- Systems Design: Determines how the new system will function to meet business needs defined during analysis.
- Systems Implementation: Creating, acquiring, assembling system components defined in design, and activating the new system.
- Systems Maintenance and Review: Checking and modifying the system to meet evolving business needs.
Information Systems in Society, Business, and Industry
- Information systems are developed to meet the needs of various organizations and individuals.
- The speed and widespread use of information systems pose security and ethical threats.
- Security, Privacy, and Ethical Issues: Individuals' privacy is a significant concern with the potential for personal data disclosure, loss or theft. Social networks can impact workplace dynamics.
Computer and Information Systems Literacy
- Computer Literacy: Knowledge about hardware, software, databases, and telecommunication functions.
- Information Systems Literacy: Understanding how data and information are used by individuals, groups, and organizations. Includes understanding why and how this technology is applied.
Information Systems in Functional Areas of Business:
- Functional areas of business: Finance and accounting, sales and marketing, manufacturing, human resource management, legal information systems.
Information Systems in Industry:
- Industries utilizing information systems: Airline & Transportation, Investment & Banking, Publishing, Healthcare, Retail, Power Management, Professional Services & Management Consulting.
Global Challenges in Information Systems:
- Global challenges: Cultural and language differences, time and distance, infrastructure, currency, product and service variations, technology transfer issues, national and regional laws, and trade agreements.
