The Product Owner maximizes the value of the product by constantly collaborating with stakeholders.
He/She is responsible for maintaining the product backlog order by sequencing the items to best achieve company goals.
Product backlog items are constantly updated by the Product Owner who looks for the latest insights and market needs.
The Product Owner also ensures that the product backlog is visible, transparent and clear to everyone, inside and outside the Scrum team.
Keep in mind: transparency is important to understand what product features are completed and which are the ones the development team will work on.
