What is the main purpose of the Product Backlog?

The main purpose of the Product Backlog is to prioritize and manage all the work that needs to be completed for the product. This living artifact is essential for guiding the development team on what needs to be addressed next, ensuring that the most valuable work is completed first. It is dynamic, allowing items to be added, modified, or reprioritized as new insights and feedback emerge throughout the development process.

The Product Backlog encompasses various items such as user stories, enhancements, bug fixes, and technical work, all of which contribute to delivering a successful product. By maintaining an orderly and prioritized backlog, the Scrum team ensures that they are always focused on delivering value to stakeholders and can adapt to changes efficiently.

In contrast to the other choices, collecting feedback after the product is released doesn't capture the ongoing nature of backlog management. While documenting technical debts can be useful, it is only a portion of what the backlog includes and does not encapsulate its broader purpose. Furthermore, treating the Product Backlog as a static document contradicts the agile principles of adaptability and responsiveness to change. The backlog must evolve as new information and requirements surface, allowing the team to iterate effectively.
