Definition

User Stories (or stories) in Agile form the building blocks of Software Development. It is a simple description of a feature, that’s told from the perspective of the user of the system, aka the person who desires/requires the feature. The focus is overall to move away from writing about requirements, and instead talk about them. All User Stories are usually 1-2 written sentences in form.
