UX design involves a wide range of different practices from coding to experience prototyping and physical making. It also involves working with people from many different disciplines. Interdisciplinarity means working with processes and methods from adjacent fields, such as physical computing or ethnography. It also means producing work that can take various forms such as a service proposition, a physical artefact, and a visual representation. UX designers should be comfortable collaborating across disciplines i.e. with partners from very different backgrounds. Often design is the discipline that provides the vocabulary and methods that make interdisciplinary collaboration possible. UX designers should therefore explicitly develop the competency to lead or guide interdisciplinary work from the perspective of shared aims and understandings. Careful use of materials can be an important part of this, along with a considerate and generous approach.
