A product is a bet, and someone has to make sure the team spends its talent on the right problems. That is the product owner's craft, and this guide teaches all of it: understanding customers and stakeholders, setting direction through vision and strategy, experimenting and prioritising under uncertainty, and turning decisions into a product backlog and shipped increments.

Version 2.0 places the role on the ground where it is practised today. When AI makes execution cheap, the bottleneck moves to deciding well what to build: the product owner doesn't lose relevance, it gains it. The guide covers both sides of AI —working with it as a professional tool and owning products that embed it— and, for every technique, distinguishes what a framework prescribes, what named authors recommend, what is common practice, and what is the guide's own judgment.

Written for newcomers and seasoned practitioners alike, it is the reference syllabus for Scrum Manager's core Product Owner certification. Published under a Creative Commons licence (CC BY-NC 4.0).
