Study Notes
User Stories
- User stories are used to provide high-touch customer experiences by taking ownership of new cases and communicating with customers.
- Each user story should have at least one acceptance criteria that is independently testable and answerable with either true or false.
Importance of Acceptance Criteria
- Acceptance criteria are essential for user stories, specifying the conditions under which a user story is fulfilled.
- They should be expressed clearly, in simple language, without ambiguity about the expected outcome.
- Well-written acceptance criteria benefit multiple stages and stakeholders of a project.
Writing Acceptance Criteria
- Acceptance criteria should state intent, not a solution, focusing on the what, not the how.
- They are added to a user story after the workshopping of the user story statement is finished.
INVEST Checklist
- The INVEST checklist, created by Bill Wake in 2003, is used to assess the quality of a user story.
- A successful user story is one that meets the INVEST criteria.
INVEST Checklist for Evaluating User Stories
Independence
- User stories should be independent of other stories to avoid dependencies and complexities
- Ensure each story can be developed and tested independently
Negotiability
- User stories should be open to negotiation and clarification during development
- Encourage collaboration and communication between teams to refine the story
Value
- User stories should provide value to the end-user or business
- Ensure each story aligns with project goals and objectives
- Prioritize stories based on their value and impact
Estimability
- User stories should be estimable in terms of time and effort required
- Ensure the team can estimate the story's complexity and duration
- Break down large stories into smaller, estimable tasks
Size
- User stories should be small enough to be completed within an iteration
- Ensure each story can be developed and tested within a short timeframe
- Break down large stories into smaller, manageable tasks
Testability
- User stories should be testable and verifiable
- Ensure each story has clear acceptance criteria
- Write automated tests to validate the story's implementation
Common User Story Mistakes
- Mistakes to avoid when writing user stories include not engaging in story writing, having an undefined user, being feature-specific, having vague acceptance criteria, and assigning the story to the implementation team without discussion.
- These mistakes can be avoided by following the user story process properly and trusting the process.
Writing User Stories
- A user story-writing workshop is recommended at the start of a project, involving the project team to brainstorm and generate story ideas.
- Participants should engage their creativity, and the user stories can be refined as many times as needed.
- Avoid making assumptions about how the user stories will be implemented, leaving those decisions to the development/implementation team during their planning meetings.
