what is epic feature and user story in agile
In Agile methodology, Epics, Features, and User Stories are different levels of requirements, with each level providing a different degree of detail and serving a different purpose.
Epic: An epic is a large body of work that could be broken down into a number of smaller tasks. Epics are essentially a summary or an overarching goal that can span multiple iterations or even projects. They provide a high-level overview of what needs to be done. For instance, in the development of a music streaming app, an epic could be “Implement Social Media Integration.”
Feature: A feature is a chunk of functionality that delivers considerable value to users but is smaller in scope than an epic. It typically fits within a single iteration or sprint and represents a shippable component of the software. Each epic can be broken down into multiple features. For instance, within the epic “Implement Social Media Integration,” a feature might be “Share a song to Facebook.”
User Story: A user story is a very granular requirement that describes functionality from the end-user’s perspective. User stories are the smallest units of work and should be achievable within one sprint. They are expressed in a simple format: As a [type of user], I want [some goal] so that [some reason/benefit]. For instance, within the feature “Share a song to Facebook,” a user story could be, “As a user, I want to be able to share the song I am currently listening to on my Facebook feed so that my friends can see what I’m listening to.”
In summary, each level of requirement gives more detail than the last. An epic is broken down into several features, and each feature is broken down into several user stories. Together, they provide a hierarchical structure for managing and developing a software project.
