What is User Experience (UX) Design?

User experience (UX) design is the process design teams use to create products that provide meaningful and relevant experiences to users. UX design involves the design of the entire process of acquiring and integrating the product, including aspects of branding, design, usability and function.

Designing an experience includes not only making the software easy to use but also designing the other experiences related to the product, for example, the marketing campaign, the packaging and after-sales support. Most importantly, UX design is concerned with delivering solutions that address pain points and needs. After all, no one will use a product that serves no purpose.

UX vs UI: What’s the Difference?

You might see the “UX/UI designer” job title and think UX and UI are interchangeable. But while there is overlap, they are separate disciplines.

“User Experience Design” is often used interchangeably with terms such as “User Interface Design” and “Usability.” However, while usability and user interface (UI) design are important aspects of UX design, they are subsets.

A UX designer is concerned with the entire process of acquiring and integrating a product, including aspects of branding, design, usability and function. The story begins before the device is even in the user’s hands.

“No product is an island. A product is more than the product. It is a cohesive, integrated set of experiences. Think through all of the stages of a product or service – from initial intentions through final reflections, from the first usage to help, service, and maintenance. Make them all work together seamlessly.”

— Don Norman, inventor of the term “User Experience.”

Products that provide a great user experience (e.g., the iPhone) are thus designed with the product’s consumption or use in mind and the entire process of acquiring, owning and even troubleshooting it. Similarly, UX designers don’t just focus on creating usable products but on other aspects of the user experience, such as pleasure, efficiency and fun. Consequently, there is no single definition of a good user experience. Instead, a good user experience meets a particular user’s needs in the specific context where they use the product.

A UX designer attempts to answer the question: "How can we make the experience of interacting with a computer, a smartphone, a product, or a service as intuitive, smooth and pleasant as possible?"

UX Design—A Formal Definition

The International Organization for Standardization (ISO) defines user experience as:

“A person's perceptions and responses that result from the use or anticipated use of a product, system or service.”

— ISO 9241-210, Ergonomics of human-system interaction—Part 210: Human-centered design for interactive systems

We can break this definition into two parts:

  1. A person’s perceptions and responses.

  2. The use of a product, system or service.

In user experience, designers do not have much control over a person’s perceptions and responses—the first part of the definition. For example, they cannot control how someone feels, moves their fingers or controls their eyes as they use a product. However, designers can control how the product, system or service behaves and looks—the second part of the definition.

“One cannot design a user experience, only design for a user experience. In particular, one cannot design a sensual experience, but only create the design features that can evoke it.”

— Jeff Johnson, Assistant Professor in the Computer Science Department of the University of San Francisco

The simplest way to think about user experience design is as a verb and a noun. A UX designer designs (verb)—ideates, plans, changes—the things that affect the user experience (noun)—perceptions and responses to a system or service.

For example, when using a physical device, such as a computer mouse, we can control some aspects of the product that influence whether the user enjoys looking at, feeling and holding it:

  • The way it fits in their hand. Is it snug? Is it too big and cumbersome?

  • The weight. Does it affect their ability to move it as they wish?

  • Its ease of use. Can they use it automatically, or do they have to think hard about it to achieve a goal? 

When a person uses a digital product, such as a computer application, a few aspects that we can influence include:

  • How intuitively they can navigate through the system.

  • The cues that help guide them to their goal.

  • The visibility of the essential aspects of a task at the appropriate time.

UX Designers Consider the Who, Why, What, and How of Product Use

As a UX designer, you should consider the Who, Why, What and How of product use. The Why involves the users’ motivations for adopting a product, whether they relate to a task they wish to perform with it or to values and views that users associate with the ownership and use of the product. The What addresses the things people can do with a product—its functionality. Finally, the How relates to the design of functionality in an accessible and aesthetically pleasant way.

UX designers start with the Why before determining the What and then, finally, How to create products with which users can form meaningful experiences. In software designs, you must ensure the product’s “substance” comes through an existing device and offers a seamless, fluid experience.

UX Design is User-Centered

Since UX design encompasses the entire user journey, it’s a multidisciplinary field–UX designers come from various backgrounds, such as visual design, programming, psychology and interaction design. To design for human users also means working with a heightened scope regarding accessibility and accommodating many potential users’ physical limitations, such as reading small text.

A UX designer’s typical tasks vary but often include user research, creating personas, designing wireframes and interactive prototypes, and testing designs. These tasks can vary significantly from one organization to the next. Still, they always demand designers to be the users’ advocates and keep their needs at the center of all design and development efforts. That’s also why most UX designers work in some form of user-centered work process and keep channeling their best-informed efforts until they optimally address all of the relevant issues and user needs.

User-centered design is an iterative process where you take an understanding of the users and their context as a starting point for all design and development.

Will AI replace UX Design?

While AI can help automate tasks and help UX designers, it will not completely replace them. AI lacks the creativity and empathy that human designers bring to the table.

Human designers are better at understanding the nuances of human behavior and emotions. They can also think outside the box and develop creative solutions that AI cannot. So, while AI can help designers be more efficient and effective through data analysis, smart suggestions and automation, it cannot replace them.

Most UX designers don’t have a degree in UX or a related field. Many are self-taught and have learned through practice. While some employers may prefer candidates with at least a bachelor's degree, they may not insist on one related to design, particularly if you have a strong portfolio. Many soft skills required to succeed in the field are transferable from other professions.

Ultimately, what matters most is your ability to demonstrate important UX design skills, mastery of the design process, proficiency in industry tools, and an understanding of core UX design principles.

There are several online and offline resources to learn UX design, many for free. However, that also means a lot of misinformation is present on the internet. One credible and free resource is the Interaction Design Foundation.

We offer the world's largest open-source library of expert and peer-reviewed UX design resources. See the latest free articles here.

What tools are used in UX design?

The most basic tools in a UX designer’s arsenal are the humble paper and pen (or whiteboard and sticky notes). UX designers use different tools for different tasks in the design process. For example:

  • Survey tools such as Typeform and Google Forms help with user research.

  • Whiteboarding applications such as Miro and Whimsical are useful for affinity diagramming, brainstorming and defining user flows.

  • Interface design and prototyping tools like Figma, Adobe XD, Sketch and Marvel help designers communicate their ideas to stakeholders and developers and conduct usability testing.

There isn’t any standard UX design process. However, most teams tend to follow a variation of the 5-step design thinking process:

  1. Empathize (through user research)

  2. Define (through data analysis and synthesis)

  3. Ideate (through brainstorming)

  4. Prototype (using analog and digital tools)

  5. Test (with real users)

UX design is a highly collaborative and iterative process. Designers plug back their findings from research and testing to improve the end user's experience.

Take a deep dive into User Experience (UX) Design with our course User Experience: The Beginner’s Guide .

If you’ve heard the term user experience design and been overwhelmed by all the jargon, then you’re not alone. In fact, most practicing UX designers struggle to explain what they do!

“[User experience] is used by people to say, ‘I’m a user experience designer, I design websites,’ or ‘I design apps.’ […] and they think the experience is that simple device, the website, or the app, or who knows what. No! It’s everything — it’s the way you experience the world, it’s the way you experience your life, it’s the way you experience the service. Or, yeah, an app or a computer system. But it’s a system that’s everything.”

— Don Norman, pioneer and inventor of the term “user experience,” in an interview with NNGroup

As indicated by Don Norman, User Experience is an umbrella term that covers several areas. When you work with user experience, it’s crucial to understand what those areas are so that you know how best to apply the tools available to you.

In this course, you will gain an introduction to the breadth of UX design and understand why it matters. You’ll also learn the roles and responsibilities of a UX designer, how to confidently talk about UX and practical methods that you can apply to your work immediately.
