Given that an agile project is underway and a sprint is in progress, what is the most effective action for a team to take if key stakeholders introduce new requirements that might affect the current sprint goals?
Continue with the sprint without acknowledging the new requirements to maintain the sprint's velocity.
Ignore new requirements until the current project phase is complete to avoid disruptions.
Record the new requirements in the product backlog for prioritization and planning in subsequent sprints.
Halt the current sprint and start planning a new sprint to incorporate the new requirements.
