In this great TED Talk, Margaret Gould Stewart of Facebook discusses the challenges of designing on a global scale. While Stewart’s work focuses on design for the giants of the internet, many of the principles she imparts are applicable to any kind of UX designs. She begins by identifying two important qualities that are needed to be effective at UX design on this scale: audacity and humility. UX professional need to try new and bold concepts, while maintaining the humility necessary to remember that UX is about the user and not the designer’s ego, a valuable lesson for anyone working in UX. Another important lesson that Stewart offers is the huge difference that little changes can make. Adding an option to tell your friend why you don’t like a photo they posted of you increased the number of people who messaged their friends asking to take undesirable photos down from 20% to 60%. As the world of UX becomes more advanced and more competitive, smaller changes will start to have a much larger impact. Never overlook the advantage that even the smallest of changes could bring to your UX. Stewart also emphasizes the need to understand your audience and design for them. This means ensuring functionality over a range of different platforms and sometimes even in different languages. This video offers a wealth of great insights for anyone working in UX.
