    Study Notes

    Alpha Testing

    • Performed early in the development process, before beta testing
    • Simulates real user scenarios using black box and white box testing techniques

    Beta Testing

    • Performed by real users in real environments
    • Considered a form of external User Acceptance Testing
    • Final test before product release
    • Beta versions are released to a limited number of users for feedback
    • Helps reduce product failure risks and improve quality through customer validation

    Debugging

    • The process of identifying and fixing remaining bugs in a program.
    • Performed by developers during the development process
    • Often uses both white-box and black-box testing techniques.

    User Documentation

    Printed Manuals

    • Provide detailed guidance on using the system
    • Can be difficult and expensive to produce and distribute
    • Updates and edits are challenging due to the physical format
    • Advantages include: always available, no internet required, resistant to damage

    Online Help Files

    • Convenient and cost-effective to create
    • Require internet connection and a device to access
    • Easy to update and edit
    • Disadvantages include: reliance on internet access, potential device failures

    User Training

    Formal Classroom Training

    • Involves a teacher and students in a structured learning environment
    • Allows for question answering and addressing complex topics
    • Can be expensive and inflexible, not personalized

    User Involvement

    • Essential for system development.
    • Prevents mismatch between system features and user needs.
    • Contributes to user acceptance and reduces training time.

    Data Collection Techniques

    Interviews

    • One-on-one meetings with users.
    • Allows for clarification, observation of verbal and non-verbal behavior, and insight into user emotions
    • Time consuming to conduct, unstructured interviews can be difficult to analyze, users might not be comfortable.

    Direct Observation

    • Observing users as they interact with the system
    • Allows for collection of various data types independent of user bias
    • Time consuming, users may change behavior if aware of being observed, the "Hawthorne Effect" can occur.

    Usability and Accessibility

    • Usability - a measure of how effectively, efficiently, and satisfactorily users can interact with a product
    • Key usability aspects: Effectiveness, Efficiency, Learnability, Memorability, Error Handling, and Satisfaction.

    Digital Systems

    • Accessibility - Ensuring that everyone can use and benefit from digital systems, incluing those with disabilities.
    • Methods to improve accessibility:
      • Alternative Text for Images: Descriptive text to make images accessible for those with visual impairments.
      • Captioning and Transcripts: Providing captions and transcripts for audio and video content for users with hearing impairments.
      • Color Contrast: Using sufficient contrast so that users with color vision deficiencies can read easily.
      • Usability Issues in Cellphone Applications:
      • Small screens
      • Battery Dependency
      • Limited storage
      • Network connectivity issues
      • Complex user interface
      • Inconsistent visual display
      • Readability concerns
      • Poor efficiency
      • Usability and Accessibility for Websites:
      • Usability Issues:
        • Complex design
        • Non-logical or inefficient workflows
        • Inconsistent visual display
        • Poorly designed user interface
        • Lack of accessibility for users with disabilities

    System Flowcharts

    • Illustrate the sequence of steps involved in solving a problem
    • Show processes, inputs, outputs, and decision points
    • Use specific symbols to represent different components
