32: Measuring UI Quality with Sara, Aaron and Patrik
Play • 42 min

For the third and final episode focusing on UI quality, Pascal is joined by Sara, Patrik and Aaron to discuss how design reviews happen at Facebook. Instead of looking at static screenshots alongside the code, reviews now include a dynamic representation of the view hierarchy that not only allows for inspection of properties but also directly highlights violations of Facebook's design standards for accessibility and usability. Learn how all of this grew out of a tool suite originally built for the web and much more in episode 32 of Inside Facebook Mobile.
