When should new work or further decomposition of work be added to the Sprint Backlog?

The correct approach is to add new work or further decomposition of work to the Sprint Backlog as soon as they are identified. This practice aligns with the core principle of agility, which emphasizes flexibility and responsiveness to change within a Sprint.

When new insights or requirements are discovered during the Sprint, it's crucial for the Scrum Team to adapt and incorporate that information without unnecessary delay. Adding items to the Sprint Backlog promptly allows the team to address the evolving needs of the project, enabling them to maintain focus and deliver the most valuable outcomes by the end of the Sprint. This fosters continuous improvement and the ability to respond to stakeholder feedback effectively.

Moreover, the Scrum framework encourages collaboration and communication among team members and with the Product Owner. Immediate incorporation of new work helps in refining understanding and priorities, ensuring that the team remains aligned with the overall goals of the Sprint. This approach also enhances transparency in the work being done, as it keeps the Sprint Backlog up to date and reflective of the team's actual workload.
