Backlog
- PO knows what the value should be, and when to do it (how important it is, priorized)
- UI/UX must define how it looks like, behave and it's user impact
- AX analizes the impact in terms of user experience
- SEO must be aware of any new content that has to be ranked
- QA must define acceptance criteria and test plans
- devTeam must help PO to refine tasks in actionable tasks
