The Product Backlog is an ordered list of what is needed to improve the product, and it is the single source of work undertaken by the Scrum Team. The Product Owner is responsible for ordering the Product Backlog items by value, risk, priority, and dependencies. The Product Backlog should be transparent and accessible to the Scrum Team and the stakeholders, so that everyone can understand the scope and progress of the product development. Therefore, options A and B are true statements about the Product Backlog.
Option C is not true because the Product Backlog items can be expressed in various formats, such as user stories, use cases, scenarios, or any other way that clearly conveys the intent and value of the item. User stories are a common and useful technique, but not a mandatory one.
Option D is not true because the Product Backlog is not a fixed and complete specification of the product, but rather an emergent and dynamic artifact that evolves over time. The Product Backlog items are refined and clarified by the Product Owner and the Developers throughout the product development process, and new items can be added or removed as needed. The Product Backlog does not need to be fully defined before the first Sprint begins, but only enough to support the first Sprint Planning.
Option E is not true because the Product Owner is not the only source of ideas and requirements for the product. The Product Owner collaborates with the Developers and the stakeholders to discover, validate, and prioritize the Product Backlog items. The Product Owner may delegate the authority to add items to the Product Backlog to others, but remains accountable for the ordering and the value of the Product Backlog.
Option F is not true because the Product Backlog does not replace the communication and collaboration between the Developers and the stakeholders. The Product Backlog represents the input of all stakeholders, but it is not a substitute for direct feedback and interaction. The Developers need to engage with the stakeholders to understand their needs, expectations, and feedback, and to deliver a valuable product increment that meets the Sprint Goal and the Definition of Done.
