What Are the Key Tasks and Responsibilities of a UI/UX Designer?

While UI/UX designer responsibilities may vary from company to company, the end goal is always the same: the responsibility of a UI/UX designer is to achieve overall user satisfaction with a product.

UI/UX designers continually look for ways to improve the product experience, even for bestselling products that have been on the market for years. They may do this by making the product faster, easier to use, or more fun. Video game patches are a great example because they’re iterative and are often launched in response to user feedback: while the initial product may be perfectly functional, patches are necessary to fix bugs and deal with unforeseen edge cases. Sometimes patches are rolled out together with additional content in order to placate longtime users and increase the chances of in-game purchases, thereby increasing customer lifetime value.

7 Key Responsibilities of UI/UX Designers

At its core, UI/UX design encompasses the entire user experience. For a physical product, this includes packaging, the ease of transporting the product to your car, and assembling it. Swedish furniture brand IKEA, which positions itself as a low-cost provider, packages furniture in flat-packed boxes so customers can transport the items in their own vehicles, thereby eliminating delivery fees. The installation instructions contain large diagrams that make it easy for users to self-assemble items without paying for extra help.

When it comes to a digital product, UI/UX design includes the purchasing process, technical troubleshooting, and the process of obtaining updates or patches.

This means UI/UX designers have several key responsibilities.

  • Conducting user research. A big part of a UI/UX designer’s key duties is learning about users and their behavior, goals, motivations, and needs. UI/UX design teams may collect data via various methods, such as interviews with users/stakeholders, competitive analysis, online surveys, and focus groups. The data is analyzed and converted into qualitative and quantitative information that guides decision-making.
  • Creating user personas. Another important UI/UX designer responsibility is identifying key user groups and creating representative personas of their behaviors and demographics. Personas can be used to make in-depth scenarios, a day-in-the-life of a persona, which shows how the product fits into the user’s everyday routine.
  • Determining the information architecture of a digital product. UI/UX designers need to organize content within an app or website to guide the user to accomplish tasks or educate them about the product. An effective information architecture tells users where they are and how to find the information they need. A chatbot with quick-answer prompts is a good example of this.

  • Designing user flows and wireframes. One of the key duties of a UI/UX designer is creating a low fidelity representation of a design. Wireframes represent a user’s journey as they interact with a website or app, including UI elements such as buttons or images. These are represented in a simplified version using placeholders.
  • Creating prototypes. UI/UX designers need to generate an interactive final version of the product pre-development, which is either clickable or tangible. It should enable the user to test the main interactions of the product. Modern prototyping tools even allow designers to record prototypes as videos to guide users through the product’s design functions.
  • Testing the product on real users. A key responsibility of a UI/UX designer is gathering feedback from users based on a minimum viable product (MVP). An MVP is the first iteration of a product with the minimum qualifications required for go-to-market. Product testing can be structured (designers gather user feedback by asking specific questions) or unstructured (the user is left to their own devices to figure out how to use the product. Feedback is gathered based on users’ natural responses, rather than explicit questioning.

  • Presenting insights to key stakeholders. UI/UX designers spend a lot of time sharing their research with upper management and product teams to ensure design insights are implemented and acted upon. An effective presentation paints a picture of what the product will be like, how it will improve the user’s life, and offer concrete examples of how it made users feel. A UI/UX designer must be able to sell their ideas by understanding business objectives while also advocating for the user.
