Study Notes
User Needs & Interviews
- Understanding user needs is crucial for effective design.
- Methods for user focus include interviews, workshops, low-fidelity prototyping, and evaluations.
- Including users ensures the product meets expectations.
- Interviews are used to gain insights into user needs, operations, and processes.
- Target interviewees are defined (users and stakeholders).
- Questions in interviews should be prepared (what do they do, how do they do it, what information do they need).
- The interview process involves introduction (goals, ethical considerations, consent), warm-up questions, a main session of clear questions, cooling-off questions, and closing with summaries and thanks.
- Tips for effective interviews include avoiding jargon, compound sentences, leading questions and biases.
- Audio/video recordings and notes help capture data.
- Interview data is summarized using patterns and examples.
User Group Analysis
- Purpose is to understand specific user needs by analyzing specific groups.
- Helps create targeted designs by identifying user characteristics and contexts.
- Key components include who (background, age, gender, education, computer knowledge), why (primary goals and motivations), what (tools, equipment), where (physical and social environments), when (frequency and duration of use), and importance (prioritizing user groups in design).
- Steps for group analysis include identifying user characteristics, conducting interviews, creating user stories and outlining tasks needed to reflect the user needs.
- Example project idea: A children's storytelling app using AI to mimic a parent's voice.
UX Goals
- Define and measure the intended user experience.
- Influence design decisions by setting emotional and functional benchmarks.
- Focus on desirable user experience factors like fun, engaging, reward, motivation, and surprise, while avoiding undesirable factors like frustration, boring interactions and annoying features.
- UX goals are used to guide design and measure success in prototypes.
- Examples include security, joy, and competence for specific user groups in an application.
Low-Fidelity Prototyping
- Early-stage design focused on structure and functionality, not aesthetics.
- Used for validating navigation and interaction flows.
- Used for quickly gathering feedback for iterative improvements.
Happy Paths
- The ideal sequence of steps a user takes to complete a task without errors; a smooth system usage.
- Guides the design of user-friendly interfaces.
Defining User Stories
- Use format: "As a [user group], I want to [achieve goal] so that [reason]".
- Example stories include "As a parent, I want to record my voice reading a book so my child can feel connected", or "As a child, I want to choose stories using images so I can read independently."
Intermediate Prototyping and Error Messages
- This involves transitioning from low-fidelity to intermediate prototypes
- Incorporating results from previous testing to refine designs
- Error messages should be polite, precise, and constructive and address user deviations.
- A user should be guided back to the intended workflow and given options for actions, if any are available.
Website Design
- Understand fundamental principles of web and app design.
- Prioritize user tasks over aesthetics
- Use grid-based layouts for consistent and responsive designs
- Use breadcrumbs and clear navigation elements
- Design menus with clear labels, use internal and outbound links (and inbound links) to improve navigation
- Consider mobile device designs to optimize for touch-screen use
- Include guidelines for web usability
- Design functionality and prioritize users' task needs over aesthetic concerns.
Testing Low-Fidelity Prototypes
- Validate design functionality before high-fidelity iterations.
- Identify usability problems and refine tasks for a stronger design.
- Testing ensures better alignment with user needs.
Functional and Non-Functional Requirements
- Establish clear requirements for software design and development.
- Focus on both functional and non-functional aspects.
- Functional requirements define what the system should do.
- Non-functional requirements define how the system should perform (e.g., security, scalability).
- Non-functional requirements focus on the system attributes rather than functionality.
UML (Unified Modeling Language) and Class Diagrams
- UML is a graphical language for specifying, visualizing, and documenting system designs.
- Understand and practice using use case diagrams, class diagrams, and sequence diagrams to document the static structure of a system and to visualize system structure.
- UML elements include classes, attributes, methods, inheritance, associations, and compositions.
Testing Types and Goals
- Understand and differentiate between functional and non-functional testing (e.g., unit testing, integration testing, system testing, acceptance testing, alpha and beta testing).
- Functional tests focus on whether the system meets specified requirements while non-functional testing focuses on performance, security, and usability, etc; of the software.
- Key testing methodologies include think-aloud testing, heuristic evaluation.
- Using both black-box and white-box testing methodologies is required.
UX Testing Techniques
- Understand and apply different UX testing methodologies to evaluate and refine design effectiveness.
- Techniques like think-aloud testing, heuristic evaluation, and usability problem lists are used to evaluate a system's structure, navigation, and responsiveness.
- The think-aloud protocol involves watching users interact with a product or platform to understand their experience. Using a structured problem list helps to prioritize issues based on severity and frequency.
User-Centered Design
- Highlight the importance of involving users throughout the software design process.
- Emphasize iterative design and the integration of user feedback.
- Early Focus on Users: Understanding user needs, behaviors and goals.
- Empirically measure reactions and analyze user performance; metrics like effectiveness (success rate), efficiency (time/effort) and user satisfaction (perception).
- Focus on iteratively testing and refining design based on feedback.
Software Processes and Maintenance
- Software processes and development methods such as Waterfall, Agile (Scrum, Kanban) and Rational Unified Process (RUP) are discussed.
- Understanding different types of software maintenance, including corrective maintenance, adaptive maintenance, perfective maintenance, and preventive maintenance.
- Emphasize iterative development and user feedback to develop effective designs.
