User stories are a crucial aspect of modern software development, with over 70% of companies employing Agile methodologies now using them to manage their projects. In this glossary, we will cover various aspects of user stories, including their definition, how they work, benefits, use cases, best practices, and a selection of top books on the subject.
“The goal of a user story is to deliver a product increment that is of immediate business value to the user or customer.” – Mike Cohn
What is a user story? Definition of User narrative
A user story is an informal, natural language description of one or more features of a software system written from the perspective of an end user or stakeholder. User stories are a key component of Agile development frameworks, such as Scrum and Extreme Programming (XP), where they help to capture and communicate user requirements in a human-readable and easily understandable manner.
ℹ️ Synonyms: Agile story, Development story, Story, User case, User story card.
How it Works
Developers use user stories to break down software projects into manageable chunks that focus on delivering valuable increments of functionality to end-users. Each story is a high-level description of a specific feature, often starting with the phrase “As a [type of user], I want [some specific functionality] so that [some benefit is achieved].” For example: “As a customer, I want to be able to view my order history so that I can keep track of my purchases.”
To prioritize user stories, developers often use the “MoSCoW” method, which divides them into “Must-Have,” “Should-Have,” “Could-Have,” and “Won’t Have” categories. During development, a user story may go through various stages, such as design, coding, testing, and documentation, before being deemed complete.
Benefits of Using User Story
- Improves communication: User stories foster collaboration and communication among developers, stakeholders, and end-users, ensuring that everyone understands the end goal and the reasons behind specific requirements.
- Helps prioritize development: By focusing on the needs of the end-users, user stories enable developers to prioritize features that deliver the most value to the customers, thus increasing the chances of project success.
- Facilitates change: Agile development frameworks that use user stories are often more adaptable to change, as they involve frequent feedback loops and prioritize incremental development.
- Increases flexibility: User stories can be easily reprioritized or changed based on new information or shifting business requirements, offering more flexibility in project management.
- Simplifies estimating work: User stories often provide a consistent format for measuring the size, complexity, and time required for each task, making it easier to estimate resources and plan development activities.
User Story Use Cases
User stories are applicable in various scenarios in software development:
- Project planning: User stories help development teams understand the scope of a project and plan out the features that need to be built by determining their order of importance based on the user’s needs.
- User requirements: User stories help in translating a user’s requirements into a format that is easily understandable by the development team and testable by quality assurance teams.
- Feature prioritization: They help in prioritizing software features by ensuring that the most valuable functionality is built first.
- Change management: When there are changes in project requirements or scope, user stories offer a flexible approach to adapt and reallocate resources accordingly.
- Documentation: Finally, user stories can serve as lightweight requirements documentation that is easy to maintain and update throughout the project lifecycle.
While there is no one-size-fits-all approach to using user stories, certain best practices can help development teams make the most of this technique. These practices include reinforcing collaboration among team members, investing time in creating clearly defined and testable user stories, making sure they are focused on delivering tangible value to the end-users, involving the entire team in planning and estimation, using frameworks and tools that promote iterative development (such as Scrum and Jira), and encouraging regular feedback and communication among the team, stakeholders, and end-users alike.
