What is a System?

• A system comprises interrelated components functioning together to achieve common objectives.
• Systems possess clearly defined boundaries.

Information Concepts

• An information system (IS) collects, manipulates, stores, and disseminates data/information to meet objectives.
• Information systems are used extensively by diverse professionals, including sales representatives, managers, and financial advisors.
• Information systems are pivotal tools for career success, empowering businesses to boost revenue and curtail costs.
• Information is considered one of an organization's most valuable resources, often mistaken with data.

Data, Information, and Knowledge

• Data is the raw facts, comprising fundamental building blocks of information.
• Information organizes data in a way that offers value beyond its constituent facts.
• A process represents a set of logically linked tasks, transforming data into information.
• Knowledge embodies the awareness and comprehension of an information set.
  • Data is transformed into information through applying knowledge to organize and manipulate it (Figure 1.2).

Characteristics of Valuable Information

• Accurate & complete information are crucial for sound decision-making, preventing possible financial losses.
• Some characteristics take precedence over others depending on the specific needs and context.

The Value of Information

• Information's value is directly linked to its contribution in supporting decision-makers in achieving organizational goals.
• Robust information assists individuals and organizations in more efficient and effective task execution.

What is an Information System?

• A collective, interrelated group of components including inputs, processes, and outputs, capable of gathering, manipulating, storing, and delivering data/information, whilst providing a feedback mechanism for refining system operations.

Input, Processing, Output, and Feedback

• Input involves gathering and capturing data.
• Processing converts raw data into meaningful outputs.
• Output entails the generation of useful information, usually in the form of reports or documents.
• Feedback represents the information the system provides for correcting inputs or processes.

Three Fundamental Types of Information Systems

• Personal IS enhances productivity for individuals.
• Group IS facilitates collaboration among team members.
• Enterprise IS enables and sustains structured interactions within and outside of organizations (e.g., employees, customers, suppliers, government agencies).

Manual and Computerized Information Systems

• Information systems can be either manual or computerized.
• Manual systems, for instance, involve investment analysts manually creating graphs and trend lines.
• Computerized systems often track stock indexes and market trends to predict opportune times for purchasing or selling stocks.

Computer-Based Information Systems (CBIS)

• A CBIS constitutes a collection of hardware, software, telecommunications technology, people, and procedures, aimed at gathering, manipulating, storing, and processing data into pertinent information.

Computer-Based Information Systems (CBIS): Elements

• Hardware encompasses physical computer equipment.
• Software encompasses the computer programs directing operations.
• Databases collate facts and pertinent data into organized files (often consisting of two or more interconnected data files).
• People is the most significant element, representing active users of technology and utilizing the system.
• Procedures refer to the rules, policies, methods guiding system usage.
• Telecommunications describes networks and the Internet for enabling electronic communication.
• Intra/Extranet functionalities aid in data exchange inside and outside an organization to access authorized system resources.

Business Information Systems

• Common business information systems often include or are used concurrently with e-commerce, transactions, & mobile commerce, and management & decision-support functions.
• Other, more niche systems, such as VR technology, serve particular needs.

Electronic and Mobile Commerce

• E-commerce encompasses a wide variety of online business transactions, including business-to-business (B2B), business-to-consumer (B2C), consumer-to-consumer (C2C), and business-government (B2G) transactions.
• Mobile commerce (m-commerce) specifically refers to transactions conducted via handheld devices.
• E-business utilizes information systems to support all activities within a company.

Enterprise Systems: Transaction Processing Systems and Enterprise Resource Planning

• TPS systems record and process business-related exchanges (e.g., payments, sales).
• Enterprise resource planning (ERP) systems manage various aspects of a company's operations (e.g., production, finance, human resources).

Information and Decision Support Systems

• Management information systems (MIS) generate summaries of routine information.
• Decision support systems (DSS) facilitate problem-specific decision-making.

Specialized Business Information Systems

• Knowledge management systems (KMSs) facilitate the storage and use of an organisation's knowledge.
• Artificial intelligence (AI) involves creating systems that function similarly to human intelligence – like vision systems, robotics, learning systems, specialist AI tools like expert systems and neural networks which use the concept of AI; and Natural language processing enabling text & speech understanding and processing by systems.
• Virtual reality and multimedia create immersive experiences.
• Expert systems simulate the capabilities of human experts.

Systems Development

• The processes of establishing and modifying existing business systems.
• Outsourcing involves delegating portions of systems development to external specialists.

Systems Investigation and Analysis

• System investigation involves gaining a clear understanding of issues or opportunities.
• System analysis defines the existing system and its associated problems and possibilities.

Systems Design, Implementation, and Maintenance and Review

• System design blueprints the system to accommodate business demands.
• System implementation consists of establishing and integrating systems.
• Systems maintenance and review continuously evaluates and adjusts systems based on evolving needs/requirements.

Test your knowledge on the basics of Information Systems, including types, components, and their organizational value. This quiz is based on the course outline and the textbook 'Principles of Information Systems' by Ralph Stair & George Reynolds.
