This document discusses effective product ownership. It emphasizes that product owners must define and translate a vision into value that is delivered incrementally for the business, customers, and team. Product owners deliver value by building a "value team" of stakeholders to understand perspectives and mine for requirements, then ordering and prioritizing requirements through techniques like Kano analysis and MoSCoW. Product owners should "artifact" requirements by documenting the intended audience, source, and discovery method to provide context.
