WTWD 610 - Usability Testing & Iteration
| Term | Definition | Example |
|---|---|---|
| Usability Testing | The process of evaluating a digital product or prototype by testing it with representative users. Usability testing helps identify usability issues and gather feedback to improve the design. | Conducting a usability test where users complete tasks on a prototype and providing feedback on their experience. |
| Iteration | The process of refining and improving a design through repeated cycles of testing, feedback, and adjustments. Iteration helps create a more user-friendly and effective product. | Making changes to a website layout based on user feedback and retesting the new version. |
| User Feedback | Information and opinions provided by users about their experience with a product or prototype. User feedback is essential for identifying areas of improvement and validating design decisions. | Collecting feedback from users about the ease of navigation on a new app. |
| Test Plan | A detailed document outlining the objectives, methodology, tasks, and participants for a usability test. A test plan ensures that the usability test is structured and comprehensive. | Creating a test plan that includes specific tasks for users to complete, such as finding information on a website. |
| Task Scenario | A realistic scenario given to users during a usability test to simulate how they would interact with the product in real life. Task scenarios help evaluate the usability of specific features or functions. | Asking users to book a flight on a travel website during a usability test. |
| Think-Aloud Protocol | A usability testing technique where users verbalize their thoughts and actions while interacting with a product. This helps researchers understand the user's thought process and identify usability issues. | Asking users to speak their thoughts aloud as they navigate through an app during a usability test. |
| Moderated Usability Testing | A type of usability testing where a facilitator guides users through the test, provides instructions, and observes their interactions in real-time. This allows for immediate clarification and deeper insights. | Conducting a usability test in a lab setting with a facilitator present to assist users. |
| Unmoderated Usability Testing | A type of usability testing where users complete tasks on their own without a facilitator. This method is often conducted remotely and allows for more natural user interactions. | Using online tools to conduct a usability test where users interact with a prototype independently. |
| Heuristic Evaluation | A usability inspection method where experts review a product based on established usability principles (heuristics). This helps identify usability issues without involving end users. | Experts evaluating a website based on Nielsen's 10 usability heuristics. |
| Usability Metrics | Quantitative data collected during usability testing to measure the effectiveness, efficiency, and satisfaction of a product. Common metrics include task completion rate, error rate, and time on task. | Recording the time it takes for users to complete a task on a prototype and calculating the average time. |
| Accessibility | The practice of designing digital products to be usable by people with a wide range of abilities and disabilities. Accessibility ensures that everyone can access and interact with the product. | Creating form input fields in Figma that are compatible with screen readers. |
| A/B Testing | A method of comparing two versions of a design to determine which one performs better based on user interactions and feedback. A/B testing helps make data-driven design decisions. | Testing two different homepage layouts to see which one leads to more user sign-ups. |
