1. What is user experience (UX) design?

UX design considers the elements that shape a user’s experience with a product or service, how these elements make the user feel, and how easy it is for the user to accomplish their desired tasks.

This could mean anything from how a physical product feels in your hand, to how straightforward the checkout process is when buying something online. The goal of UX design is to create easy, efficient, relevant, and all-around pleasant experiences for the user.

“User experience encompasses all aspects of the end-user’s interaction with the company, its services, and its products.”
— Don Norman, Cognitive Scientist & User Experience Architect

UX designers combine market research, product development, strategy, and design to create seamless user experiences for products, services, and processes.

They build a bridge to the customer, helping the company to better understand—and fulfill—their needs and expectations.

The difference between UX and UI design

When talking about UX, the term user interface (UI) design will inevitably crop up. However, it’s important to recognize that, despite often being used interchangeably, UX and UI are two different things.

It’s important to outline that user interface design is not the same as UX design. UI refers to the actual interface of a product, the visual design of the screens a user navigates through when using a mobile app, or the buttons they click when browsing a website.

UI design is concerned with all the visual and interactive elements of a product interface, covering everything from typography and color palettes to animations and navigational touch points (such as buttons and scrollbars). You can read more about the work of UI designers in our guide.

“UX is focused on the user’s journey to solve a problem; UI is focused on how a product’s surfaces look and function.”
— Ken Norton, Partner at Google Ventures, Ex-Product Manager at Google

UX and UI go hand-in-hand, and the design of the product interface has a huge impact on the overall user experience. Learn more about the difference between UX and UI design in this guide.

UX design is everywhere: the layout of a supermarket, the ergonomics of a vehicle, and the usability of a mobile app.

2. What does a UX designer do?

“How do I explain what I do at a party? The short version is that I say I humanize technology.”
— Fred Beecher, Director of UX, The Nerdery

UX designers seek to make everyday products, services and technology as user-friendly and accessible as possible. They employ design thinking to reconcile the user’s desires with technical feasibility and business viability.

The Design Thinking Process

The following diagram shows the Design Thinking Process, adapted from the d.school. The Design Thinking Process can be broken down into four different stages: inspiration, conceptualization, iteration, and exposition.

During the inspiration stage, the UX designer seeks to understand and observe. To do this, they conduct extensive research and competitor analysis in order to fully grasp the problem or challenge they are setting out to solve. This involves interviewing those who are, or will be, directly engaged with the product.

The user experience designer then uses this feedback to identify the user’s goals, emotions, pain points, and behaviors. All of this information helps to form user personas. The next step is to consider what these personas are trying to accomplish when using a particular product, and the journey they will take to do so. The designer considers information architecture and uses various techniques, such as card sorting, to map out user flows.

Once the user flows have been determined, the designer knows what steps the user needs to take to complete their desired tasks. They will visually brainstorm solutions for each of these steps, creating wireframes and prototypes of what the final product might look like.

With prototypes to hand, the UX designer will then conduct usability tests to see how users interact with the product. This shows whether or not the user is able to complete their desired tasks or if changes need to be made.

UX designers not only come up with solutions to user problems; they also need to present their ideas and designs to key stakeholders as part of their day-to-day work.

Company size determines the scope of what a UX designer does

This is just a broad overview of the UX design process. In reality, tasks will vary depending on both the size and the specific needs of the company.

Larger companies might employ a team of designers, each focusing on a specific aspect of the process, such as research or visual design.

In smaller companies and startups, it’s not unusual for the UX designer to wear many different hats and take on the whole spectrum of tasks.

Key questions UX designers ask themselves

No matter what product or service they are designing or what stage of the process they are at, UX designers will ask themselves the following questions:

  • Is the product usable? Is it logical, self-explanatory, and easy to use?
  • Does the product or service solve an existing user problem?
  • Is it accessible to different categories of users? You can read more about accessibility in design further on.
  • Is the product or service desirable? Does it create a positive experience that the user would be happy to repeat?

What tools do UX designers use?

UX designers rely on a number of different tools as they go about their work. At the research and inspiration stage, they will use survey and polling tools as well as video chat software to interview users and gather as much information as possible.

There are also specific programs for wireframing, prototyping, and usability testing, with Balsamiq, InVision, and UsabilityHub among the most popular in the industry.

In addition to design-specific programs, designers use communication and project management tools to keep track of their work at all times. You can learn more about UX design tools in our beginner’s guide.

What kinds of projects do UX designers work on?

As the tech industry grows, the field of UX design is becoming increasingly varied. UX designers can find themselves working on a wide range of projects within various contexts. The following are just some applications for UX design.

Website, app, and software design

In the age of the internet and smartphones, the usability of a website, mobile app, or piece of software will largely determine its success on the market. Together with UI designers, UX designers are responsible for ensuring a smooth online experience for the user.

From e-commerce websites to dating apps, from CRM software to web-based email clients, each and every online journey you take has been carefully designed by a UX professional.

Voice design

Voice user interfaces are revolutionizing the way we interact with technology. In the U.S., around 50% of adults use voice search on a daily basis, and ComScore estimates that, in the early 2020s, 50% of all searches will be voice-based.

UX designers have a huge role to play in the rise of voice, as products like Amazon Alexa can only be successful if they are user-friendly and accessible to the masses. Designing for voice requires a slightly different approach to that of websites and apps: learn more in this beginner’s guide to VUI design.

Virtual reality (VR) and augmented reality (AR)

With the global VR market expected to be worth around $44.7 billion by 2024, UX designers will increasingly be required to design immersive experiences. Likewise, since the Pokemon Go craze hit, augmented reality has also been working its way into the mainstream. More and more, UX designers will have to adapt their approach to ensure the latest technologies are accessible and user-friendly.

Service design

UX design doesn’t only apply to tangible objects and digital products; experiences need to be designed, too. This is where service design comes in.

As explained on its Wikipedia page: “Service design is the activity of planning and organizing people, infrastructure, communication and material components of a service in order to improve its quality and the interaction between the service provider and its customers. Service design may function as a way to inform changes to an existing service or create a new service entirely.”

Whenever you buy a coffee, stay in a hotel or use public transport, your experience is the result of service design, and service design methodology is very similar to that of classic UX design.

3. UX design disciplines: The quadrant model

UX is a broad umbrella term that can be divided up into four main disciplines: Experience Strategy (ExS), Interaction Design (IxD), User Research (UR), and Information Architecture (IA).

Diagram depicting the 4 quadrants of UX design

UX Design Disciplines: The Quadrant Model

Experience Strategy (ExS)

UX design is not just about the end user; it also brings huge value to the business providing the product or service. Experience strategy is all about devising a holistic business strategy, incorporating both the customer’s needs and those of the company.

Interaction Design (IxD)

Interaction design looks at how the user interacts with a system, considering all interactive elements such as buttons, page transitions, and animations. Interaction designers seek to create intuitive designs that allow users to effortlessly complete core tasks and actions.

If you want to learn more about this discipline and how it relates to the other two main design areas, read our guide to UX, UI, and Interaction Design.

User Research (UR)

UX design is all about identifying a problem and designing the solution. This requires extensive research and feedback from existing or potential customers.

During the research phase, UX designers will launch surveys, conduct interviews, and usability testing, and create user personas in order to understand the end user’s needs and objectives. They gather both qualitative and quantitative data and use this to make good design decisions. Learn how to conduct user experience research in our article on it.

Information Architecture (IA)

The short answer is that information architecture is the practice of organizing information and content in a meaningful and accessible way. This is crucial in helping the user to navigate their way around a product. To determine the IA of any given product, information architects consider the relationship between different sets of content.

They also pay close attention to the language used and ensure that it is both convincing and consistent. We’ve created an in-depth guide to Information Architecture if you want to learn more about it.

Within these four areas, there is a whole host of sub-disciplines. As you can see in the following graphic, user experience design is so much more than just a case of sketching and wireframing. It’s a multidisciplinary field, drawing upon elements of cognitive science and psychology, computer science, communication design, usability engineering and more.

5. The value of UX design

Among the many UX myths and misconceptions is the erroneous assumption that UX design is “just a fad.” But in reality, the value of UX design is immense, not only for the end user but also for the business or brand behind the user experience.

To understand the lasting value of UX design, it helps to explore its vast historical impact. There is evidence to suggest that, as early as the 5th century BC, Ancient Greek civilizations designed their tools and workplaces based on ergonomic principles.

A definitive timeline of the history of UX design

Today, the definition of a UX designer’s role will vary depending on which industry or company you talk to. There’s a growing tendency for companies to hire for very specific roles, such as UX researcher or interaction designer, to cover all of the different aspects of user experience.

But one thing remains constant: From a user perspective, good UX design ultimately enables us to go about our daily lives as effortlessly as possible. From setting an alarm to chatting with friends online, listening to music, or using a calendar app, the ease with which we complete these actions is the result of good design.

When designing these experiences, UX designers must consider how they can bring value to all kinds of users. They do this by practicing inclusive design—otherwise known as universal or accessible design.

Universal design (UD)

As motivational speaker Molly Burke explains, universal design is the practice of “designing and building everything to be accessed, enjoyed and understood to its fullest extent, by everyone, regardless of their size, their age, their ability, or their perceived ability.”

Universal design follows seven key principles:

  1. Equitable use: The design is useful and marketable to people with diverse abilities.
  2. Flexibility in use: The design accommodates a wide range of individual preferences and abilities.
  3. Simple and intuitive use: The use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
  4. Perceptible information: The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
  5. Tolerance for error: The design minimizes hazards and the adverse consequences of accidental or unintended actions.
  6. Low physical effort: The design can be used efficiently and comfortably and with a minimum of fatigue.
  7. Size and space for approach and use: Appropriate size and space is provided for approach, reach, manipulation, and use regardless of the user’s body size, posture, or mobility.
