System Analysis and Design Quiz

Systems Development Phases

• Systems analysis phase focuses on collecting and interpreting data, identifying problems, and breaking down a system into its components.
• Planning phase involves creating a new business system or replacing an existing one by defining its components.

Purpose of Systems Analysis

• The purpose of systems analysis is to assess and evaluate current systems in order to determine requirements for new systems or improvements.

Specifications in Systems Development

• The phase that specifies what the system should do is known as the requirements specification phase.

Understanding Systems Design

• Systems design involves creating a detailed plan for how a system will function, including technical specifications, system architecture, and user interfaces.

Data vs. Information

• Data refers to raw facts and figures that have not yet been processed or interpreted.
• Information is processed data that has meaning and can be used for decision-making.

Examples of Data

• Data can include numerical values, text entries, observations, or any other raw input that can be recorded and analyzed.

Using Data to Obtain Information

• Monthly expense on milk can be analyzed to generate information such as spending trends, budgeting needs, or cost comparisons over time.

Examples of Information

• In the given example, information could include insights such as the average monthly expense on milk or identifying whether spending on milk has increased or decreased.

Main Point

• The main point emphasizes the distinction between data and information, underscoring the importance of processing and interpretation in making data meaningful.
