Whether you’re an in-house designer, a UI/UX design student, or a design enthusiast who plans to run a design agency, this article will explain 45 UX and UI terms you need to know to earn a competitive advantage during all design stages. 

UX glossary and other UI terms are finally on your way!

1. A/B Testing

A/B testing is one of the popular terms to use when describing mobile apps. It is a method also called split testing. It showcases two versions of a product to users to compare them and understand which one performs better. With this tool, you can confirm hypotheses for potential improvements. You can also determine what works better for your audience based on statistical performance analysis.

2. Affinity map

Affinity mapping is a productive user research method that is well suited to teamwork. In simple words, designers write down their thoughts and engage with sticky notes. This UX method is a great way to immerse designers and stakeholders in user research by letting them organize design ideas through sticky notes.

3. Accessibility

UX accessibility is a method that examines a user's accessibility issues. This is particularly essential in terms of users with disabilities. So, designers have to provide the easiest access to the design products/services. They need to be aware of potential accessibility issues, such as seizures, auditory, motor/mobility and color blindness. In the end, many users—whatever their abilities—need to understand and use the design product/service with ease. 

4. API

An application programming interface (API) enables two programs to communicate. Using an API, a developer can request services from an operating system (OS) or other application, and expose data in different contexts and channels.

5. Agile

Another UX design term which combines Agile software development with UX principles. Agile software teams should have at least one UX specialist as well as a culture that recognizes and understands the value of UX. The Agile UX method is helpful because it ensures that useful design products are developed at all stages. Since it is not feasible to get feedback from the end-users at all times, agile can help software teams to address any possible issue quickly. Therefore, they avoid the risks of getting negative reactions/feedbacks at the moment when the product hits the market.

5. Breadcrumbs

Navigation elements such as breadcrumbs tell users where they are on a website. Users can use these elements to navigate between website pages. Usually, they are placed near the top of the page (in most cases, right below the browser's address bar).

7. Back-end(development)

Back-end development refers to developers' work on server-side software, which is hidden from our eyes. Back-end developers focus on maintaining tools to ensure high website performance. They use code and take care of databases, application programming interface (APIs), architecture, and servers.

8. Card Sorting

A UX research technique that helps designers to evaluate the information architecture of the product. Designers use card sorting to categorize and understand information. This technique  creates a foundation for robust information architecture (IA), and strong IA allows for the creation of a navigation system that matches users’ expectations.

9. Competitive audit

A competitive audit is a research method that involves tracking, analyzing, and comparing competitors’ strategies. This method encourages designers to make better decisions and determine what strategies could work for better brand visibility and product/service enhancement. By using a competitive audit process, UX designer scan dig deep into the design industry trends and stay on top of the competitive market.

10. Customer Journey Map

 A journey map in UX design represents a visual depiction of the steps customers take while using a product or service. The map is like a graph showing the client's interaction with the product. It helps identify gaps or pain points in the customer's experience. It also encourages designers to establish a UX flow that will put more value on customers overall experience with a design product.

Design thinking is an insightful process of generating and implementing design ideas through 5 stages.

  1. Stage 1: Empathize—Gain an empathetic understanding of users' needs
  2. Stage 2: Define—Synthesize your findings from the previous phase
  3. Stage 3: Ideate—Generate ideas from the previous two phases and identify innovative solutions
  4. Stage 4: Prototype—Identify solutions for each possible issue
  5. Stage 5: Test—Test your solutions from the prototypes to see if there are more possible issues

15. End Users

UX designers have end users they will be designing for. In simple terms, end users are people who interact with a design. However, end users are not necessarily customers because they don’t need to purchase a product/service. They could be employees, individuals or entrepreneurs who simply use the product.

16. Experience Architecture (EA)

Experience architecture combines interaction design, information architecture (IA), and experience design (XD) to illustrate the user's journey. It provides a comprehensive view of the users' navigation and helps designers to develop a functional design structure.

17. Eye Tracking

An interesting UX method that tracks users’ eye movements while interacting with a design. It allows designers to understand where exactly users are looking, whether it’s a website, app, or other visual data. Eye tracking is excellent for optimizing a design and accentuating visual elements most attractive to the human eye.

21. Fidelity

Designers use the word "fidelity" when they refer to the design details and level of functionality. There is a difference between low, mid and high-level of fidelity. While low fidelity designs look similar to the final design, high fidelity designs are as close to the final design as possible.

22. Focus Group

A focus group in user experience research aims to gather the opinions of a carefully selected group of participants (between 5 and 10). The answers are recorded, analyzed and then reported to enhance further product development and decision-making. With focus groups, you can get quick user insights over a short period of time. This method is typically used during early UX research phase, but it is also useful after the product has been launched.

25. Iterative Design

Iterative design is a design strategy that takes many iterations to move towards a design that suits users in the best possible way. The steps involved in this design method are prototyping, planning, implementing, testing, empathizing and then repeating the process. So, by studying the results of several iteration tests, designers can prepare the changes for the final design more efficiently.

33. Persona

A designer creates personas based on user data in order to understand more about different user types, their perspectives, user characteristics, and goals. Creating these personas will help designers dig deep into the user's needs and develop a more effective design.

34. Pain Points

Pain points are the problems users face while navigating through an app, for example. Once designers identify these pain points, they can create a good user flow and, as a result, user-friendly design.

35. Prototype

A prototype is a model in an early stage of a proposed product solution used to test and improve the design concept. Based on prototypes, a UI/UX designer can identify user pain points and make appropriate adjustments in the design development.

36.  QA (Quality Assurance)
