    Study Notes

    Systems Development Life Cycle

    • The Systems Development Life Cycle includes five stages: Systems Planning, Systems Analysis, Systems Design, Systems Implementation, and Systems Operation, Support, and Security.

    Systems Planning Phase

    • The Systems Planning Phase begins with a system request that describes problems or demand changes in an information system.
    • The phase involves a feasibility study that reviews the anticipated cost and recommends a course of action based on operational, technical, economic, and time factors.

    Systems Analysis Phase

    • The purpose of the Systems Analysis Phase is to build a logical model of the new system, starting with requirement modeling.
    • The phase involves investigating business processes and determining what the new system must do.
    • The end product of the phase is the system requirements document.

    Systems Design Phase

    • The purpose of the Systems Design Phase is to create a blueprint that satisfies all documented requirements for the system.
    • The phase involves designing the user interface and identifying all necessary outputs, inputs, and processes.
    • The result of the phase is documented in the system design specification.

    Systems Implementation Phase

    • The Systems Implementation Phase involves installing the new system, writing and testing programs, and documenting them.
    • The objective of the phase is to deliver a completely functioning and documented information system.

    Systems Operation, Support, and Security

    • The Systems Operation, Support, and Security Phase involves maintaining, enhancing, and protecting the system.
    • IT staff must abide by standards for computer ethics, be discreet about confidential information, and follow the Ten Commandments of Computer Ethics.

    Feasibility Study

    • A feasibility study is a measurement of how beneficial or practical an information system will be to an organization.
    • Feasibility analysis involves estimating the benefits of solving problems and opportunities and estimating the costs of developing the expected system.
    • There are four categories of feasibility tests: technical, economic, operational, and schedule feasibility.

    Operational and Technical Feasibility

    • Operational feasibility involves determining whether the system will be compatible with the organization's existing operating procedures.
    • Technical feasibility involves determining whether the system can be developed using existing technology.

    Input Design

    • Input design involves how data will be captured and entered into the information system.
    • The six main objectives of input design are:
      • Select a suitable input and data entry method.
      • Reduce input volume.
      • Design an attractive data entry screen.
      • Use validation checks to reduce input errors.
      • Design required source documents.
      • Develop effective input controls.

    Input Devices

    • Examples of input devices include biological feedback devices, credit card scanners, and bar code readers.
