User Experience Design Flashcards

Question 1

What is user experience design, and how does it differ from user interface design?

Accepted Answer

User experience design shapes everything a person encounters while using a product, including goals, emotions, and effort. User interface design is narrower, covering the screens, controls, and visual elements people touch. A polished interface cannot rescue a product that solves the wrong problem.

Question 2

What does usability mean in the context of user experience?

Accepted Answer

Usability describes how effectively, efficiently, and satisfactorily specific users can complete specific tasks in a given context. Effectiveness asks whether people reach their goal, efficiency asks how much effort it takes, and satisfaction asks how pleasant the experience feels. Usability is one part of user experience, alongside factors such as usefulness and desirability.

Question 3

What is a user persona and why do design teams create one?

Accepted Answer

A persona is a fictional but research-based profile that represents a group of users with shared goals, behaviors, and needs. Teams create personas to keep decisions focused on real people rather than on the assumptions of designers or stakeholders. A good persona rests on interview and observation data and names a clear goal.

Question 4

What is a user journey map, and what does it reveal?

Accepted Answer

A user journey map is a visual representation of the steps a person takes to accomplish a goal, across channels and over time. Each stage records the user's actions, thoughts, emotions, and pain points. Mapping reveals moments of friction and opportunities for improvement that might be invisible when designers look only at individual screens.

Question 5

What is the difference between a goal and a task in user experience work?

Accepted Answer

A goal is the outcome a person wants, such as booking a trip. A task is a sequence of actions a person performs to reach that goal, such as searching for flights, comparing prices, and entering payment details. Designers study goals to understand motivation and study tasks to find where the flow can be simplified.

Question 6

Why does accessibility belong at the center of user experience design?

Accepted Answer

Accessibility means designing so people with a wide range of abilities, including those who rely on assistive technology, can perceive, understand, and operate a product. Treating accessibility as a core requirement improves experiences for everyone, because features such as clear labels, logical focus order, and sufficient color contrast help all users.

Question 7

What is the difference between qualitative and quantitative research in UX?

Accepted Answer

Qualitative research gathers rich, descriptive insight into why people behave as they do, using methods such as interviews, observation, and diary studies. Quantitative research measures how many people do something, using methods such as surveys and analytics. Strong projects combine both, since numbers reveal what is happening while conversations explain the reasons behind it.

Question 8

Why should a designer test ideas with real users rather than rely on personal opinion?

Accepted Answer

Designers are not typical users, and their familiarity with a product makes it hard to notice confusing labels or unnecessary steps. Testing with real people exposes the gap between what the team intended and what users actually understand. A handful of participants often reveals major problems, so teams can correct direction before development begins.

Question 9

What is a usability test, and what does a facilitator typically do during one?

Accepted Answer

A usability test observes participants as they attempt realistic tasks with a product or prototype. The facilitator explains the session, gives tasks without coaching, avoids leading questions, and asks participants to think aloud so that the team can see where confusion arises. Observers record task success, errors, and hesitation, which inform design decisions.

Question 10

What is the difference between a moderated and an unmoderated study?

Accepted Answer

In a moderated study, a facilitator guides participants in real time, either in person or remotely, and can ask follow-up questions when something surprising happens. In an unmoderated study, participants complete tasks on their own, often through online software. Moderated studies yield deeper insight, while unmoderated studies reach more people more quickly.

Question 11

What is a contextual inquiry, and why do researchers conduct one?

Accepted Answer

A contextual inquiry is a field method in which a researcher observes and talks with people while they perform real work in their own environment. Researchers conduct one because context reveals workarounds, interruptions, and unspoken knowledge that people often forget to mention in an interview held in a conference room.

Question 12

What makes an interview question open-ended, and why does that matter?

Accepted Answer

An open-ended question invites a full answer in the participant's own words, such as "Walk me through the last time you booked a trip," rather than a yes or no. This matters because closed questions tend to produce short, agreeable responses, while open questions surface stories, reasoning, and details that the team did not expect.

Question 13

What is a survey's main strength and main weakness in user research?

Accepted Answer

A survey's main strength is reaching many respondents quickly and producing comparable numbers across groups. Its main weakness is that it captures only what people choose to report, so answers can reflect memory errors, social desirability, or question wording rather than actual behavior. Surveys work best alongside observation or interviews that explain their patterns.

Question 14

How does a researcher choose a sample of participants for a study?

Accepted Answer

Researchers choose participants who match the target users defined by the project, including relevant behaviors, experience levels, and contexts, rather than whoever is easiest to recruit. Small groups often yield enough insight in qualitative studies, while quantitative work needs larger samples to support comparisons. Screening questions help confirm that each participant fits the criteria.

Question 15

What is affinity mapping, and when is it useful?

Accepted Answer

Affinity mapping is a method for organizing many research observations into groups based on natural relationships. Members write each observation on its own note, group related notes, and name each cluster as a theme. It is useful after interviews or field studies, when a team needs to turn raw data into shared insights.

Question 16

What is a research repository, and why do teams keep one?

Accepted Answer

A research repository is a shared, searchable collection of research findings, notes, recordings, and personas that a team can revisit over time. Teams keep one so that insights are not lost when projects end or members change, and so new designers can learn from earlier studies rather than repeating them.

Question 17

What is information architecture in user experience design?

Accepted Answer

Information architecture is the structure that organizes content and functions so people can find, understand, and manage information. It defines categories, labels, relationships, and hierarchy, and it determines which items sit near each other and how deep a person must go to reach them. It is largely invisible when it works.

Question 18

What is a card sort, and what does it help designers learn?

Accepted Answer

A card sort is a research activity in which participants group content items written on cards and name the groups in their own words. It helps designers learn how people mentally organize information, which labels make sense to them, and where their expectations differ from the current structure.

Question 19

What is a tree test, and how does it differ from a card sort?

Accepted Answer

A tree test checks whether people can find items within a proposed site hierarchy by asking them to locate targets using only text categories. A card sort is generative, helping designers discover a structure, while a tree test is evaluative, helping them judge whether a structure they have already drafted works.

Question 20

Why do navigation labels matter so much in an interface?

Accepted Answer

Navigation labels are the words people use to predict what they will find behind a link or menu item. Vague labels such as "Resources" or "Solutions" force users to click around to learn what they mean, while specific labels that match users' vocabulary help people choose correctly on the first try.

Question 21

What is the purpose of breadcrumbs in a website or app?

Accepted Answer

Breadcrumbs display the path from the homepage to the current page as a row of links, such as Home, then Shoes, then Running. They show users where they are within the hierarchy and let them move up several levels with a single click. They support orientation most on sites with deep structures.

Question 22

What is a faceted search, and when should a product offer one?

Accepted Answer

Faceted search lets people narrow a set of results by applying filters, called facets, such as price range, brand, size, or rating. It suits large collections that users compare, such as products or listings. Facets should show only relevant options and update counts so people can see the effect of each choice.

Question 23

What is the difference between a flat and a deep navigation structure?

Accepted Answer

A flat structure places most destinations only a few clicks from the home screen. A deep structure arranges content in many nested levels, so each destination sits several clicks away. Flat structures reduce steps but can overwhelm people with choices, while deep structures organize content but risk losing users.

Question 24

How should a site handle a search box alongside its navigation menu?

Accepted Answer

A search box works best as a complement to clear navigation, not a replacement for it. Many people type when they know what they want, so the search field should be easy to find and tolerate partial or misspelled terms. Teams should review common searches that return nothing to find content or labeling gaps.

Question 25

What are common usability heuristics, and why do evaluators use them?

Accepted Answer

Usability heuristics are broad rules of thumb that describe qualities of a good interface, such as visibility of system status, consistency, error prevention, and recognition rather than recall. Evaluators use them in heuristic reviews, where experts inspect an interface against these principles to find likely problems quickly and cheaply, before or alongside user testing.

Question 26

What does affordance mean, and how do designers communicate it?

Accepted Answer

An affordance is a property of an object that suggests how it can be used, such as a button that looks raised and invites pressing. Designers communicate affordances through shape, size, contrast, placement, and familiar patterns, so that people can tell what is clickable, draggable, or editable without reading instructions.

Question 27

What is Fitts's law, and how does it guide interface layout?

Accepted Answer

Fitts's law describes how the time to reach a target depends on the distance to it and the target's size, so larger targets placed closer to the pointer are faster to hit. Designers apply it by making common controls large and nearby, and by placing menus at screen edges where pointers stop naturally.

Question 28

What is feedback in interaction design, and why is it important?

Accepted Answer

Feedback is the system's response to a person's action, such as a button changing appearance when pressed, a progress indicator during loading, or a message confirming that a form was saved. It is important because people need to know whether their input was received, what is happening now, and whether they need to act next.

Question 29

How should a designer handle errors so that people can recover from them?

Accepted Answer

Good error handling explains what went wrong in plain language, points to the exact field or step involved, and suggests a specific way to fix it. Designers also prevent errors where possible, for example through sensible defaults and format hints. Error messages should never blame the user, and they should keep entered data.

Question 30

What is consistency in interface design, and what kinds of consistency matter?

Accepted Answer

Consistency means that similar elements look and behave the same way across a product, so people can transfer what they have learned to new situations. Internal consistency applies within one product, such as one icon for one action throughout. External consistency follows conventions users already know from other products, such as a familiar cart icon.

Question 31

What is cognitive load, and how can designers reduce it?

Accepted Answer

Cognitive load is the amount of mental effort that working memory must spend to understand and use something. Designers reduce it by removing unnecessary elements, grouping related items, using familiar terms, breaking long forms into steps, and showing only the choices a person needs at that moment.

Question 32

What is progressive disclosure, and when is it useful?

Accepted Answer

Progressive disclosure shows key options first and reveals advanced features on request. It is useful when a product has many capabilities, because it keeps the first screen calm while keeping deeper functions findable. Designers must decide what stays visible, since hiding a common feature forces extra clicks.

Question 33

What is a prototype, and what purposes can it serve?

Accepted Answer

A prototype is a simplified, testable representation of a design, ranging from a paper sketch to an interactive model that behaves like the final product. Prototypes serve to explore ideas quickly, communicate design intent to teammates and stakeholders, and gather feedback from users before engineers commit to building anything.

Question 34

What is the difference between low-fidelity and high-fidelity prototypes?

Accepted Answer

Low-fidelity prototypes are rough, quick versions, such as sketches or wireframes, that focus attention on structure and flow rather than visual detail. High-fidelity prototypes look and behave like the finished product, with accurate typography, color, and interactions. Low-fidelity work is cheap to change and invites candid feedback, while high-fidelity work tests visual and interaction details.

Question 35

What is a wireframe, and how does it differ from a mockup?

Accepted Answer

A wireframe is a skeletal layout that shows the placement of content, controls, and navigation without final colors, images, or brand styling. A mockup adds visual design to the layout, showing how the screen will look, including typography, color, and imagery. Wireframes help teams settle structure before visual decisions distract from the layout.

Question 36

What is a clickable prototype and what should it include?

Accepted Answer

A clickable prototype is an interactive model that lets testers move between screens by clicking, tapping, or typing as they would in the real product. It should include the flows needed for the tasks being tested, realistic content, and clear transitions between states, but it does not need every feature or edge case.

Question 37

Why should teams plan for iteration instead of treating a design as final?

Accepted Answer

Iteration means repeating cycles of design, testing, and revision, so each round is informed by evidence about what users actually do. Teams that treat a design as final tend to discover problems after launch, when fixes are costly and users have already formed negative impressions. Planning for iteration builds learning time into schedules.

Question 38

What are the core measures typically recorded in a usability test?

Accepted Answer

Common usability test measures include task success rate, time on task, number of errors, number of assists needed from a facilitator, and participant satisfaction ratings. Success rate shows whether people reach the goal, while errors reveal where the design causes trouble. Teams should define measures before testing so results compare fairly across rounds.

Question 39

What is A/B testing, and what must a team control to trust its results?

Accepted Answer

A/B testing compares two design versions by showing each to a different user group and measuring which performs better on a defined goal. To trust the results, a team must randomly assign users, change only the compared element, and collect data before deciding. Without these controls, chance or unrelated factors may explain the difference.

Question 40

How can a team decide whether a usability issue is severe enough to fix first?

Accepted Answer

Teams often rate severity by considering how frequently the issue occurs, how badly it affects the person's goal, and whether the problem can be worked around. An issue that blocks checkout ranks higher than a cosmetic misalignment nobody notices. Several team members should rate severity so one person's judgment does not dominate.
