A product owner is a role in a product development TEAM or a Scrum team who is responsible for the product backlog, making sure that it is up-to-date in TERMS of priorities and has the ITEMS which translate back to the vision. The Product Owner represents the business or user and is accountable for collaborating with the consumer to define what features will be in the product release. 

The Product Owner works with the stakeholders to get the right requirements, right in the sense, help the USERS to devise the requirements which they might not see or comprehend at that point. This not only improves the relationship with our customers but also helps to build up the trust. And at the other end, the Product Owner helps the delivery team/development team understand the vision and the requirements. Hence, this role is kind of a bridge between the two ends, holding tight the two corners and EFFECTIVELY enhancing the smooth communication. This role is really critical as it handshakes at both the ends – the development team and the stakeholders.
