    Study Notes

    Usability Key Components

    • Effectiveness measures the percentage of users successfully completing a given task, and tracks errors made.
    • Efficiency records the time needed for users to complete tasks; shorter times indicate higher efficiency. Resource utilization, like clicks and keystrokes, is also considered.
    • Satisfaction is gauged via user surveys, often employing Likert scales to quantify feedback. The Net Promoter Score (NPS) measures the likelihood of users recommending the product.
    • Learnability evaluates the time new users take to become proficient with the system. Retention assesses how well users maintain knowledge and skills over time.
    • Accessibility ensures the system is usable by people with varied abilities, adhering to accessibility guidelines.

    Methods for Assessing Usability

    • Usability Testing (Moderated): A facilitator observes users interacting with the system, asking questions, and noting challenges.
    • Usability Testing (Unmoderated): Users complete tasks independently using remote tools, recording their interactions for analysis.
    • Heuristic Evaluation: Usability experts evaluate the system against established usability principles (heuristics) to spot potential problems.
    • Surveys and Questionnaires (Post-Task): Immediate surveys gather feedback on user experience after completing tasks. The System Usability Scale (SUS) is a standardized questionnaire used to measure perceived usability.
    • Analytics and Metrics (Web Analytics): Analyze user behavior data like page views, bounce rates to identify patterns and areas for improvement.

    Designing Forms

    • Purpose and Clarity: Each form should have a clear purpose and goal, stating what it aims to gather (information, transactions, feedback). Users must understand the expectations.
    • Logical Layout: Form fields should be logically organized to follow the natural flow of information. Related fields are grouped together, with headings or sections improving readability, making form completion easier.
    • Field Design: Input controls (text fields, dropdowns, checkboxes) should match the data type. Fields need clear labels and examples (or placeholders).
    • Validation and Feedback: Implement real-time validation to provide immediate feedback on user input. Highlight errors and offer clear correction instructions to enhance the user experience.
    • Accessibility: Ensure forms are accessible to all users, including those with disabilities. Label clearly, provide alternative text for images, and assure keyboard navigation.
    • Minimize User Input: Reduce the amount of required user input by using defaults, auto-fill options, and pre-populated fields whenever possible.

    Designing Reports

    • Purpose and Audience: Define the report's purpose and target audience. Tailor report content to satisfy the audience's needs and provide relevant information.
    • Structure and Organization: Use a logical structure with headings, subheadings, and bullet points to highlight key information. This layout aids in locating needed details quickly.
    • Visual Elements: Use charts, graphs, and tables that effectively present data in digestible formats, enhancing user comprehension of complex information.
    • Clarity and Conciseness: Use clear and concise language, avoiding jargon and overly technical terms. Summarize key findings and recommendations prominently and concisely.
    • Consistency: Maintain consistent formatting, fonts, and colors throughout the report for a professional look and enhanced readability.
    • Interactivity: Incorporate interactive elements (if applicable) to increase engagement and user exploration of data.

    Integration Testing

    • Definition: Verifies interactions between different software modules or components, ensuring they function as intended.
    • Purpose: Identifies issues like interface mismatches or data flow problems when combining different software units.
    • Types: Top-Down Integration, Bottom-Up Integration, Big Bang Integration.
    • Tools: Postman (API testing), Selenium (web application testing).
    • Benefits: Early detection of interface defects, ensures combined components function correctly, and validates data exchange between modules.

    System Testing

    • Definition: Evaluates the full integrated software system against its specified requirements.
    • Purpose: Validates end-to-end functionality and ensures the software meets business needs and user expectations in a production-like environment.
    • Types: Functional testing verifies system functions; non-functional testing evaluates performance, security, usability, and reliability; regression testing ensures recent changes don't adversely affect existing functionality.
    • Tools: QTP, LoadRunner, JMeter.
    • Benefits: Comprehensive system evaluation, defect identification before deployment, ensures software readiness.

    Installation Strategies

    • Direct Installation ("Big Bang"): Replaces the old system with the new one instantaneously.
    • Advantages: Quick transition
    • Disadvantages: High risk of failure with no fallback option.
    • Parallel Installation: Runs both the old and new systems concurrently for a period.
    • Advantages: Lower risk, safety net for users, gradual familiarity with the new system.
    • Disadvantages: Higher operational costs.
    • Phased Installation: Deploys the new system in stages or modules.
    • Advantages: Reduces risk, allows for testing and adjustments within smaller increments.
    • Disadvantages: Longer overall implementation time.
