    Study Notes

    What is a System?

    • A system is a set of elements or components that work together to achieve a goal.
    • Systems take inputs, transform them, and produce outputs.
    • They exist within an environment but are separate from it.
    • Systems are made up of sub-systems.
    • They use feedback from their environment for control.

    Information Systems

    • An information system is a set of components that collect, process, and disseminate data and information.
    • They provide a feedback mechanism to meet a specific objective.
    • Information Systems are often referred to as IS, short for Information Systems or Information Services.
    • In many companies, IS is the name of the department responsible for computers, networking, and data management.
    • Other companies may refer to the department as IT (Information Technology) or MIS (Management Information Services).

    Schematic Model of an Information System

    • Input: The activity of gathering and capturing data.
    • Processing: Converting or transforming data into useful outputs.
    • Output: Useful information, usually in the form of documents and/or reports.
    • Feedback: Information that helps to improve the system.

    Components of Information Systems

    • The six key components are:
      • Hardware: Devices like monitors, processors, printers, and keyboards that accept, process, show data and information.
      • Software: Computer programs and their supporting manuals. They provide machine-readable instructions that direct hardware to produce information.
      • Data: Facts used by programs to create useful information.
      • Telecommunications/Networks: Electronic transmission of signals for communication. Used to connect computers and equipment locally, nationally, and globally, enabling electronic communication.
      • People: The most important element. They manage, run, program, and maintain the system. Examples include IT professionals.
      • Procedures: Strategies, policies, methods, and rules for using the information system. They guide people in using the system effectively.

    Types of Information Systems

    • There are four main types:
      • Transaction Processing Systems (TPS): Collect, store, modify, and retrieve data transactions for an enterprise. Examples include sales order entry, payroll, and shipping. Ideal for routine, repetitive tasks.
      • Management Information Systems (MIS): Use TPS data to create reports that managers can utilize for making routine business decisions. Serve Middle Management.
      • Decision Support Systems (DSS): Interactive computer-based systems that help decision makers use various forms of data, knowledge, and models to solve problems.
      • Executive Support Systems (ESS): Used by senior management for strategic decision-making. Address non-routine decisions that require judgment and evaluation.

    Relationship of Systems

    • The different types of systems in an organization are interconnected.
    • TPS are major producers of information needed by other systems, which then generate information for other systems.
    • It is advantageous to integrate these systems to enable smoother information flow and provide a comprehensive view of organizational performance.

    Other classifications of Information Systems

    • Expert Systems (ES): Knowledge-based systems offering expert advice and acting as expert consultants. Examples include credit application advisors and diagnostic maintenance systems.
    • Knowledge Management Systems: Support the creation, organization, and dissemination of business knowledge within an enterprise. Examples include intranet access to best practices, sales proposal strategies, and customer problem resolution systems.
    • Strategic Information Systems: Support operations or management processes that provide a firm with strategic products, services, and capabilities for competitive advantage. Examples include online stock trading, shipment tracking, and e-commerce systems.
    • Functional Business Systems: Support operations and managerial applications of basic business functions. Examples include information systems for accounting, finance, marketing, operations management, and human resource management.

    Benefits of Information Systems

    • Businesses can:
      • Quickly, easily, and reliably collect and gather large amounts of data.
      • Store and organize large amounts of data.
      • Quickly, accurately, and consistently manipulate data.
      • Retrieve and communicate information in various useful forms.
      • Enforce business rules.

    What is Information Management?

    • IM is the collection and management of information from multiple sources.
    • The goal is to distribute this information to various audiences.
    • It aims to capture, store, and deliver the right information to the right people at the right time.
    • The objective is to help organizations and individuals access and utilize information effectively and efficiently to add value.
    • IM involves people, policies/processes, technology, and data/information.
