What is a Product Backlog?

A Product Backlog is best described as a living artifact of product requirements. This means that it is a dynamic and evolving list that reflects all desired work on a product. Unlike a fixed list, the Product Backlog is continually updated based on feedback, changes in understanding, and new information that comes to light, ensuring that it remains relevant and aligned with the needs of stakeholders and the market.

The Product Backlog is prioritized and can change as necessary, allowing the Scrum Team to adapt to shifting priorities and circumstances. This living nature is essential, as it supports the iterative and incremental approach of Scrum, where learning and adaptation play crucial roles in delivering a successful product.

The other options do not capture the essence of the Product Backlog accurately. A fixed list of product requirements implies that the requirements are static and unchanging, which contradicts the agile principle of adaptability. A summary of completed Sprints refers to the outcomes and achievements made during Sprint reviews rather than the ongoing requirements of a product. A tool for tracking team performance suggests a focus on individual or team metrics, which diverges from the core purpose of the Product Backlog as a management and prioritization tool for product development.
