User flow is an essential UX deliverable that helps the client visualize the user journey and understand how the user will interact with the application or website. It provides a framework for understanding the user experience and helps identify potential user pain points. User flow diagrams typically include the users’ tasks, the steps they need to take to accomplish those tasks, and the path they follow to complete each task. These diagrams also help to identify areas for improvement and highlight potential issues that may arise. By understanding the user flow, the client can expect to gain valuable insights into the user experience and make informed decisions that will improve the overall user experience.
