The document describes an experiment conducted by a software development team where they worked without a dedicated Product Owner for 3 months. In the experiment, the team was directly responsible for interacting with customers and prioritizing work. After the experiment, the team found that they were able to deliver more while being more customer-focused without a Product Owner acting as a proxy between them and customers. The team also realized they did not need the Product Management Expert to be present at all planning meetings to understand customer priorities. After a year of working without a Product Owner, the team was recognized as the "Best Team in Corporate R&D".
