User story mapping is a visual framework that helps product teams to better understand and plan the development of a product. It was introduced by Jeff Patton, a software engineer and product designer.
The framework consists of two main components: user stories and a map. User stories describe the needs, goals, and motivations of users or customers, and are typically written in a simple, user-focused language. The map is a visual representation of the product, showing how user stories fit together to form a cohesive product experience.
The process of user story mapping involves identifying user goals and needs, and breaking them down into smaller, more manageable stories. These stories are then grouped together into "epics," or larger features, which are arranged on the map according to their priority and relationship to one another.
User story mapping allows product teams to get a big-picture view of the product and the user experience, while also providing a framework for planning and prioritizing development work. It can be used in a variety of contexts, from software development to physical product design, and is especially useful for teams working on complex or highly user-centered projects
