These slides are adapted from a talk I gave at the Welsh Government's Marketing Awards for the LAM sector, in 2017. It offers a primer on UX - User Experience - and how ethnography and design might be used in the library, archive and museum worlds to better understand our users. All good marketing starts with audience insight. The presentation covers the following: 1) An introduction to UX 2) Ethnography, with definitions and examples of 7 ethnographic techniques 3) User-centred design and Design Thinking 4) Examples of UX-led changes made at institutions in the UK and Scandinavia 5) Next Steps - if you'd like to try out UX at your own organisation
