Checklist

Before Writing a User Story

• User need is validated (research/feedback)
• Business value is clear
• Story fits within sprint scope
• Dependencies are identified
• Technical feasibility confirmed with team

Before Sprint Planning

• Backlog is groomed and prioritized
• Top stories have acceptance criteria
• Team has seen stories in advance
• Capacity is calculated
• Sprint goal is defined

Before Accepting a Story

• All acceptance criteria are met
• Edge cases are handled
• Performance is acceptable
• Security review completed (if applicable)
• Documentation is updated
• No critical bugs remain

Anti-Patterns to Avoid

1. Writing solutions, not problems: Focus on user needs, not implementation details
2. Gold plating: Adding unrequested features
3. Scope creep: Expanding stories after commitment
4. No prioritization: Everything is P0
5. Missing acceptance criteria: Ambiguous "done"
6. Ignoring technical debt: Always new features, never maintenance
7. Stakeholder bypass: Not involving stakeholders in decisions
