How is the Product Backlog best described?

The Product Backlog is best described as a dynamic list that evolves over time as new insights are gained about the product and its customers. This characteristic is essential to Agile and Scrum practices, where the focus is on adaptability and responsiveness to change.

In Scrum, the Product Backlog is a living artifact that reflects the current understanding of the product requirements, which can change based on feedback, new opportunities, learning, and changing market conditions. This allows the team to prioritize the highest value work and ensures that the development process is aligned with the needs of the stakeholders and users.

By embracing the changing nature of the Product Backlog, Scrum teams can ensure they are continuously delivering value and refining their approach based on new information, rather than being restricted by an unchanging set of requirements. This flexibility is what supports the Agile principle of welcoming changing requirements, even late in development.
