The product owner, representing the product's stakeholders and the voice of the customer (or may represent the desires of a committee), is responsible for delivering good business results. Hence, the product owner is accountable for the product backlog and for maximizing the value that the team delivers. The product owner defines the product in terms of customer-centric outcomes (typically - but not limited to - user stories), adds them to the product backlog, and prioritizes them based on importance and dependencies. A scrum team should have only one product owner (although a product owner could support more than one team) and it is strongly advised against combining this role this role with of the scrum master. The product owner should focus on the business side of product development and spend the majority of time liaising with stakeholders and the team. The product owner does not dictate how the team reaches a technical solution, but seeks consensus among team members. This role is crucial and requires a deep understanding of both sides: the business and the engineers (developers) in the scrum team. Therefore, a good product owner should be able to communicate what the business needs, ask why they need it (because there may be better ways to achieve that), and convey the message to all stakeholders including the developers using technical language, as required. The product owner uses Scrum’s empirical tools to manage highly complex work while controlling risk and achieving value.
