As we approach the publication of the book, this site will be updated with 30 videos of interviews conducted with UX and other practitioners about getting stakeholder buy-in for UX research. Interviewees come from 7 countries and are organized in 5 different categories
All of the interviewees are world renown experts, 18 of them are authors of UX books. Definitely something to look for.
