Who Does What In UX? A detailed look at the roles and their contributions

by | Mar 31, 2024 | UX, Editors choice


Dive into the world of UX design, where it feels like there are more roles than herbs in KFC’s chicken recipe. Each role promises to make the user experience as smooth and enjoyable as possible – a bit like a Michelin-starred chef promising to turn every dish into a masterpiece. But why so many chefs in the UX kitchen? In this blog post, we reveal the secret of the many faces behind great user experience design and show how they work together to create digital products that not only work, but delight.


Why are there so many UX roles

The diversity of roles in the field of user experience design reflects the complexity and iterative nature of the design process. At the centre of this process is design thinking, an approach that is divided into five phases: Empathize, Define, Ideate, Prototype and Test. Each phase aims to develop a deep understanding of users, identify clear problems, generate innovative solutions, create prototypes and test them – a cycle that is often repeated to achieve the best possible results.

The role of specialisation in the design thinking process

The creation of specific UX roles serves to cover different aspects of this process. As the phases are closely linked, they often overlap and are iterative by nature. This iteration and overlap makes it difficult to fully define and separate the roles. However, it is this flexibility and dynamism that makes the UX design process so effective.

  • Empathise: This is where user researchers come into play, using qualitative and quantitative research methods to develop a deep understanding of users and their needs.
  • Define: In this phase, UX strategists and information architects are required to help translate the collected findings into clear, manageable problems or challenges.
  • Ideate: UX designers and interaction designers use creative techniques to develop a wide range of solutions based on the defined challenges.
  • Prototype: UI designers and product designers often work closely together to quickly create tangible prototypes that visualise the ideated solutions.
  • Test: Usability testers then conduct tests with real users to gather feedback and evaluate the effectiveness of the prototypes.</li

Dependence on the company structure

The specific organisation of these roles and how they are positioned in the design process depends heavily on the size, structure and culture of the respective company. In a start-up, some of these roles may be grouped together, with one person wearing several hats. In larger organisations, on the other hand, the roles are often more specialised and more clearly defined.

The emergence of different UX roles is a direct response to the requirements of the design thinking process and its phases. Specialisation within the UX field allows for deeper exploration and expertise in each step of the process. At the same time, the close connection and iteration between the phases requires flexible and adaptive collaboration between the different roles. This enables an effective and holistic design of the user experience that is geared towards the actual needs and behaviour of the user.


The individual roles in detail

Overlaps and collaboration

At the heart of user experience design lies the realisation that close collaboration between the different roles within the UX team is not only valuable, but crucial to the success of a project. The boundaries between roles such as UX designers, UI designers, interaction designers and others are often blurred, leading to significant overlap in areas of responsibility. This overlap creates a dynamic working environment in which innovation and creativity can flourish.

The inclusive nature of this collaboration allows teams to draw from different perspectives, which encourages the development of solutions that are both creative and deeply aligned with user needs. A coherent user experience that is consistent across all aspects of the product is ensured through this interdisciplinary coordination.

The ability to create and utilise synergies between different areas of expertise leads to results that exceed the sum of their parts. By recognising and addressing the challenges that come with this interdisciplinary way of working, teams can create an environment in which exceptional user experiences are created.
