Study Notes

Information Systems

  • Information systems (IS) are sets of interrelated components that gather, manipulate, and distribute data and information, providing feedback to achieve objectives.

  • IS helps businesses achieve goals, boost revenue, and cut costs.

Information Concepts

  • Information is one of the most valuable assets an organization has.

  • Information is often mistakenly used interchangeably with the term "data."

Data, Information, and Knowledge

  • Data is unprocessed facts.

  • Information is organized data that holds a value beyond the facts themselves.

  • A process is a series of logically related tasks performed to achieve a specific outcome.

  • Knowledge is an understanding of information and its application to support tasks.

  • Information system (IS) is a set of interrelated components that collect, process, and disseminate data and information to achieve a specific goal.

  • The components of an IS include hardware, software, data, people, and processes.

  • The transformation of data into information occurs through processing.

  • People use their knowledge to interpret information and make decisions.

  • Businesses utilize IS to provide information needed for:

    • Decision-making: This involves analysis of past trends, and forecasting future possibilities.
    • Problem-solving: IS assists in finding solutions to specific problems.
    • Control and monitoring: IS provides information for evaluating and monitoring operations and performance.

The Characteristics of Valuable Information

  • If the information in an organization is inaccurate or incomplete, it can lead to poor decisions, resulting in significant financial losses.

  • The importance of specific information characteristics depends on the type of data required.

  • Key characteristics of valuable information:*

  • Accurate: Information should be free from errors and reflect the actual conditions.

  • Complete: All information should be available, including all relevant details.

  • Relevant: Information should pertain to the specific task or decision at hand.

  • Timely: Information should be available when needed for effective decision-making.

  • Understandable: Information should be presented in a way that is easily understood by the intended audience.

  • Economical: The cost of gathering and distributing information should be justifiable.

System Concepts

  • A system is a set of components that work together to achieve a goal.

  • System components include:

    • Inputs: Data and instructions that are processed by the system.
    • Processing mechanisms: The processes that transform inputs into outputs.
    • Outputs: The results of the processing mechanisms.
    • Feedback: Information about the system's performance that is used to improve it.

System Performance and Standards

  • Efficiency assesses the ratio of output to input.

  • Effectiveness measures how well a system achieves its goals.

  • System performance standard is a specific objective for the system.

What is an Information System?

  • An information system (IS) is a collection of elements that gather, manipulate, store, disseminate data and information, and provide feedback to achieve a goal.

The Elements of an Information System

  • Input: The activity of gathering raw data.
  • Processing: Converting data into useful outputs.
  • Output: Production of useful information, often in documents and reports.
  • Feedback: Information from the system used to make changes to input or processing activities.

Computer-Based Information Systems (CBIS)

  • Comprised of hardware, software, databases, telecommunications, people, and procedures.
