Up-to-date personas result in a better UX design process. Data from 156 companies provide a baseline to understand how often to revise personas. Knowing when and how frequently to make updates will help you craft personas that are both accurate and effective.
It addresses a lot about how to create a persona for a “product”. But how about the persona for a public facility for example a train station? “Products” like these have almost a whole range of “users” ,but we are still aimed at designing the “interface” so it’s “universal” enough for literally everyone right? How is that done?
