A user story is the smallest unit of work in an agile framework. It is an informal, general explanation of a software feature written from the perspective of the end user or customer. User stories are written in non-technical language to provide context for the development team and their efforts. They are used to articulate how a software feature will provide value to the customer. User stories are composed of three aspects: a written description of the story, used for planning and as a reminder (card), conversations about the story that serve to flesh out the details of the story (conversation), and tests that convey and document details that can be used to determine when a story is complete (confirmation). User stories are one of the core components of an agile program and are used to provide a user-focused framework for daily work, which drives collaboration, creativity, and a better product overall.
