The most important role of user stories is to represent the needs of the user, replacing the traditional requirements specification. It is true that the specification carries more information, such as system functionality, compliance, vendors and other requirements, but the focus of these stories is on business value and user-centric thinking.

The formulation of user stories is at the heart of agile development, which is why we believe it is important to provide tailored mentoring from them to the members of agile teams as part of our work.
