Introduction
In Agile, requirements are organized into Epics, Features, and User Stories. This hierarchy helps teams break large business requirements into smaller, manageable tasks that can be planned, developed, and delivered incrementally.
Epic
An Epic is a large business requirement that cannot be completed within a single Sprint. It is divided into multiple Features or User Stories.
Example
Online Shopping Application
Epic: Online Shopping System
Feature
A Feature is a major functionality within an Epic that provides value to the user. A Feature is usually implemented through multiple User Stories.
Example
Feature: Shopping Cart
User Story
A User Story is a small, specific requirement that describes a feature from the end user’s perspective. It is small enough to be completed within a Sprint.
Standard Format
As a Customer,
I want to add products to my shopping cart,
So that I can purchase multiple items together.
Relationship Between Epic, Feature and User Story
| Level | Description | Example |
|---|---|---|
| Epic | Large business requirement | Online Shopping System |
| Feature | Major functionality within an Epic | Shopping Cart |
| User Story | Small user requirement | Add product to cart |
Real-World Example
