Final answer:
False. The product backlog does not need to contain everything that will be developed for the product before the first sprint.
Step-by-step explanation:
False.
Before the first sprint, the product backlog does not need to contain everything that will be developed for the product. The product backlog is a dynamic and evolving list of features, enhancements, and bug fixes that represent the requirements and priorities of the product owner and stakeholders. It is continuously refined and updated throughout the development process.
During sprint planning, the product owner and development team select a subset of items from the product backlog that are top priority for the upcoming sprint. This ensures that each sprint is focused on delivering valuable and potentially shippable increments of the product.
