User flows is a specialized skill in UX design that involves creating a visual representation or diagram of how users navigate through a product, website, or app. It involves mapping out each step a user takes, from the initial interaction to the final desired goal, to determine what actions they will take, what choices will be presented, and how they will move through the experience. User flows are critical to improving the user experience and ensuring that design decisions are based on user-centered principles. To be proficient in user flows, one must have a deep understanding of user behavior, data analysis, and UX design techniques.
