The FOLIO project is following a deliberate "user experience first" design process. Librarians and technologists are working with a user experience (UX) designer to create a prototype of the user interface. That prototype, along with a description of the functional requirements, becomes the specifications for the software development.
The current version of the prototype can be reached at: https://bit.ly/folioproject
In August 2016, Filip Jakobsen of Samhæng described the user-experience-first design process in a FOLIO Forum webinar. During that same webinar, Filip also walked through the first prototype. The recording of that webinar is at: https://www.openlibraryenvironment.org/archives/184. In January 2017 Filip returned in another FOLIO Forum to describe the technical process for creating the prototype and invited others to create their own prototype user interfaces; the recording of that webinar is at: https://www.openlibraryenvironment.org/archives/286.
Discussion about the user interface and user experience design process happens in the UI/UX category on Discuss.folio.org.
