Great Product Owners are described as 'experimenters' who understand that everything they do is a hypothesis requiring validation.
They establish feedback loops early, actively engage with users and clients, and approach product development with a scientific mindset.
The relationship between Product Owner and team must be a true partnership for success to occur.
A cautionary example is given of a technically knowledgeable Product Owner who had concrete ideas about the technology and solution, but failed to validate user needs and experienced UX issues.
