Q1. What is the difference between UI and UX?

UI is composed of elements that enable interaction between machines and humans. UI is the focus of visual elements such as colours, typography and UX is about the experience. UX and UI cannot be compared since they serve completely different purposes.  

Q2. What are the important skills for UX design professionals? 

Ans. UX designers require several technical skills such as methods of prototyping products, wireframing, agile, information architecture and using visual design software such as Figma and Sketch. They should also have the capability to conduct user and usability research. 

Q3. What is a wireframe?

Ans. A wireframe is used for layout content and page functionality. It provides a visual understanding of the page at the initial stages to allow scope for modifications in the page. It demonstrates what interface elements will exist on key web pages. These are used in the development process for establishing the basic structure of a web page before the addition of visual design or content.

Q4. What are the different types of wireframes?

Ans. There are three different types of wireframes. These include low fidelity wireframes, mid-fidelity and high fidelity wireframes. 

1. Low fidelity wireframes are the first stage in the wireframe process that is concerned with user flow to define the page’s hierarchy and structure. These are hand-drawn sketches for depicting initial layout ideas. These include menus, images and text blocks. 
2. Mid-fidelity wireframes follow on from the low-fidelity sketches for adding detail, refinement and focus primarily on the functionality. They also define various UI elements with a focus on functionality. They are present as either black/white digital or as hand-drawn sketches. The overall structure and content layout are more clearly defined. 
3. High fidelity wireframes are built upon the mid-fidelity wireframe with a focus on design and useability. These are post-iterative drawings that include behavioural characteristic elements. These drawings are detailed and high-level rendering of every component. Content is the biggest focus in this type of wireframe. Over here, designers add UI elements, text hierarchy and hover states. The purpose is to incorporate ideas and elements in this design from the previous phase. The high fidelity wireframes resemble the final product. These are created digitally. 

Q5. What do you mean by usability testing?

Ans. Usability testing is a method to assess the ease of use of a product by testing it with real users. Users are observed by researchers while they work on a task. The testing is conducted to identify usability problems, collect quantitative and qualitative data. Due to this methodology, issues are identified before coding.

Q6. What is user-centred design?

Ans. User-centred design is the set of tools that are used to design services that focus on the user requirements from beginning till the launch of the service. In this framework, usability goals, environment, tasks, product workflow, user characteristics are given attention at each stage of the design process. The user-centred design process helps software designers in accomplishing the goals of products that are engineered for the users. 

Q7. What is a website prototype?

Ans. A website prototype is the draft of the web design of the website. It allows customers to view how the website will appear in practice. Website prototyping has the following advantages:

1. Getting the idea of the final appearance of the website at the initial stage.
2. Ability to plan a realistic time frame for the project.
3. Identifying problems in the website structure.

There are three types of prototyping: paper prototyping, prototyping with professional apps and online tools. Paper prototyping is the traditional method that involves designing on paper. This type of prototyping is performed via professional apps that allow editing in a particular section of the overall prototype. When prototyping is done with online tools then developers have remote access to the prototype. 

Q8. What is user requirements capture?

Ans. User requirements capture is a research exercise in the project lifecycle to establish the project scope. This is an exercise to understand the product from the perspective of the user and to establish users’ expectations. This prevents the risk of failures in achieving project objectives.

Q9. What is card sorting?

Ans. Card sorting is a UX research method in which users organise topics into groups and use it for creating IA to suit user experience. Study participants group individual labels that are written on notecards according to the criteria that seem sensible to them. This method is meant to find how the domain knowledge of the target audience is structured. This helps in designing the information architecture of a website as per the expectations of the users. 

Q10. What is tree testing?

Ans. Tree testing is a method of evaluation of the proposed website structure. This is done by asking users to find items using the site structure that are based on the website’s terminology. The online test removes anything else other than the navigation links. The testing shows the most basic menu structure without layout and design. Users are then asked to complete 15-20 tasks per session to look for items through the site structure. This testing method is conducted at the initial stage of the design process. 

Q11. What is the difference between service design and UX design?

Ans. The fundamental difference between the two is the nature of the design problem that they are solving. UX focuses on what the end-user has encountered whereas service design focuses on how the user experience is created internally. UX includes all aspects of user interaction whereas service design refers to the planning and organisation of business resources. 

Q12. What is the difference between remote and traditional usability testing?

Ans. Remote usability testing is a remote research method where an insight platform is used for recording test participants’ screens (also voice, if needed) whenever the user interacts with the software at their own location. On the other hand, traditional usability testing requires users to be present at a different location while the test is being conducted.

Q13. What is wireflows?

Ans. Wireflows are UX deliverables that document user workflows and complex interactions for web applications and mobile. These are used for representing dynamic changes on pages within an application. It documents interactions including layouts changes, confirmation and popups. Wireflows present the full flow in front of the UX designers and allow easy visualisation to cover every use case. These are useful in projects that have complex interactions and that have few unique pages or website sections that contain many interactions. They are not useful on static websites or on the apps where clicking on a button/link navigates to another static page.

Q14. What is a task flow?

Ans. Task flow is a diagram that represents the user’s journey through a specific task. It provides a perspective on how the pieces of content connect with each other. The connection creates a path that the user travels to reach the endpoint. Task flow helps in figuring out what the user is trying to accomplish before creating the content. Content strategists can balance brand goals with customer requirements through task flow. It allows high-level concepts in the pre-layout stages of the project’s life cycle.

Q15. What is a UX sitemap?

Ans. UX sitemap is a hierarchical diagram of a website that represents how pages are linked, labelled and prioritised. Sitemaps are used in the UX design process after the discovery phase. Sitemaps are typically after personas, card sorting and user journey. It provides a complete overview that simplifies and trim off unnecessary pages. The UX sitemap helps to check whether the linked pages are SEO and user friendly.
