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.
