In a great video Agile Product Ownership in a Nutshell Hendrik Kniberg shows all aspects of the product owner role.
It comes down to:
- Vision of your product
- Communication with stakeholders and DEV team
- Capacity planning
- Burn-up charts (see Hybrid Project Management)
- Backlog grooming with stakeholders and DEV team
- Estimate size and business value of user stories
- Split up stories
- Define acceptance criteria
- Gradual insight
Thanks Hendrik for the enjoyable video!
