User stories are short descriptions of a feature or functionality from the perspective of an end user. They follow the format "As a <who>, I want <what>, so that <why>". The who is the user role or persona who will benefit from the feature or functionality. The what is the feature or functionality that the user wants or needs.
The why is the benefit or value that the user will get from the feature or functionality. User stories help translate requirements in a way that shows a product's value to the end user and helps prioritize and validate them. User stories do not provide specific details about a product early in the development lifecycle because they are usually high-level and flexible. User stories do not decrease the need for collaboration within a product team throughout the project because they require constant communication and feedback among stakeholders, developers, and testers.
