They capture requirements from the perspective of the end user, following the template: As a [type of user], I want [goal] so that [benefit]. This format helps teams understand who needs the functionality, what they need, and why it matters to them.
User stories emphasize conversation over documentation. They serve as placeholders for discussions between the Product Owner, Development Team, and stakeholders. The real value comes from the collaborative dialogue that occurs when refining these items.
Good user stories follow the INVEST criteria: Independent (can be developed separately), Negotiable (details can be discussed), Valuable (provides value to users), Estimable (team can estimate effort), Small (fits within a Sprint), and Testable (acceptance criteria can be defined).
However, user stories are not mandatory in Scrum. The Scrum Guide does not prescribe any specific format for Product Backlog Items. Teams may choose alternative formats based on their context:
1. Job Stories: Focus on situations and motivations using the format "When [situation], I want to [motivation] so I can [outcome]."
2. Use Cases: More detailed descriptions of system interactions, useful for complex technical requirements.
3. Feature Descriptions: Simple statements describing functionality needed.
4. Technical Tasks: Descriptions of technical work required for system maintenance or infrastructure.
5. Bug Reports: Documented defects requiring resolution.
6. Hypotheses: Statements framed as experiments to validate assumptions about user behavior or market needs.
The Product Owner should choose formats that best communicate requirements to the Development Team and stakeholders. What matters most is that Product Backlog Items are clear, understood by everyone, and provide sufficient detail for the team to plan and execute work effectively. The format should serve communication, not constrain it.

Why User Stories and Other Formats Matter
Understanding user stories and alternative formats is essential for Product Owners because they serve as the primary mechanism for communicating requirements and value to the development team. Effective use of these formats ensures clear communication, reduces misunderstandings, and helps teams deliver products that truly meet customer needs. For the PSPO-I exam, this topic tests your ability to understand how to express and manage Product Backlog items effectively.
What Are User Stories?
User stories are short, simple descriptions of a feature told from the perspective of the person who desires the capability. They typically follow the format:
As a [type of user], I want [some goal] so that [some reason].
For example: As a registered customer, I want to save items to my wishlist so that I can purchase them later.
User stories are not the only format for Product Backlog items. They are simply one popular technique. The Scrum Guide does not mandate any specific format for expressing requirements.
Key Characteristics of User Stories
• Independent: Stories should be self-contained and not dependent on other stories • Negotiable: They are not contracts but invitations for conversation • Valuable: Each story must deliver value to stakeholders • Estimable: Teams must be able to estimate the effort required • Small: Stories should be completable within a Sprint • Testable: Clear acceptance criteria must be definable
These characteristics are often remembered using the acronym INVEST.
Other Formats for Product Backlog Items
Use Cases: More detailed descriptions of user interactions with the system, often including preconditions, postconditions, and alternative flows.
Job Stories: Focus on the situation and motivation rather than the user role. Format: When [situation], I want to [motivation], so I can [outcome].
Feature Descriptions: Simple statements describing functionality that needs to be built.
Free-form Text: Any clear description that the team understands.
Technical Items: Tasks like refactoring, infrastructure work, or technical debt that may not fit traditional user story format.
How User Stories Work in Practice
1. Creation: The Product Owner creates user stories based on stakeholder input and product vision
2. Refinement: The Scrum Team collaborates to add detail, estimates, and acceptance criteria during Product Backlog refinement
3. Conversation: User stories are placeholders for conversations between the Product Owner and Developers
4. Confirmation: Acceptance criteria define when a story is complete
5. Splitting: Large stories (epics) are broken down into smaller, manageable pieces
The Three Cs of User Stories
• Card: The written description of the story • Conversation: Discussion between team members to understand the details • Confirmation: Acceptance criteria that verify the story is complete
Common Mistakes to Avoid
• Treating user stories as complete specifications • Skipping conversations and relying solely on written documentation • Making stories too large or too detailed • Forcing all Product Backlog items into user story format • Writing stories that lack clear value statements
Exam Tips: Answering Questions on User Stories and Other Formats
1. Remember flexibility: Scrum does not prescribe any specific format for Product Backlog items. Questions suggesting user stories are mandatory are typically incorrect.
2. Focus on value: The primary purpose of any format is to communicate value and enable understanding. Choose answers emphasizing this.
3. Collaboration is key: User stories facilitate conversation. Answers suggesting they replace communication are wrong.
4. Product Owner accountability: The Product Owner is accountable for the Product Backlog content and ordering, regardless of format used.
5. Refinement context: Details are added during refinement. Stories do not need to be fully detailed when first created.
6. Beware of absolutes: Questions stating that all items must be in user story format are incorrect.
7. Value over format: When in doubt, choose answers that prioritize delivering value and clear communication over strict adherence to any format.
8. Acceptance criteria: Understand that acceptance criteria help define when an item is Done, supporting transparency and quality.
