What Is the Difference Between User Stories and Requirements?

While most new features should be defined from the user’s perspective, in practice, when defining the requirements that development teams need to build, we often overlook the “why” from the user’s angle. The focus of a user story is on experience—what the person using the product wants to achieve. Traditional requirements focus on functionality—what the product should do. The remaining differences lie in the subtle but crucial “who,” “how,” and “when” lists.

User stories should be written in one or two sentences, capturing who the user is, what they want, and why. A simple structure for defining features or user stories is as follows:

As a ______, I want to ______, so that I can ______.

Example:

As a user, I want to reset my password so that I can regain access to the system if I forget it.

Despite different goals, both user stories and requirements ultimately aim to build a product customers love.

What Is a User Story?

User stories are requirements expressed from the end user’s perspective. User stories may also be referred to as epics, themes, or features, but they all follow the same format.

Essentially, a user story is a clearly expressed requirement. For multiple reasons, the user story format has become the most popular way to express requirements in Agile:

  • It focuses on the perspective of the person using or affected by the solution.
  • It defines requirements in language meaningful to that role.
  • It helps clarify the true purpose behind the requirement.
  • It helps define high-level requirements without diving too early into low-level details.

Identify user goals and immediately consider the business value of each requirement within the user story.

User stories are typically considered to contain three elements — the 3C:

User Story Format

The format for a user story is as follows:

These two examples demonstrate user stories at different levels, but using the same format:

At the project level:

As a <Marketing Director>, I want <to improve customer service>, so that <we retain our customers>.
