In Agile methodologies, the principle of maintaining the integrity of the sprint backlog is crucial. Once a sprint has started, the scope is typically fixed to provide a stable environment for the development team to work and deliver on their commitments. Therefore, the project manager should conduct an impact analysis to assess the consequences of introducing the compliance requirement into the current sprint.
This analysis should consider factors such as the team's capacity, the potential impact on existing commitments, and the likelihood of meeting the sprint goals. If the impact analysis suggests that adding the compliance requirement is feasible without significantly disrupting the sprint, the team may choose to incorporate it. However, this decision should be made collaboratively with the team, and the product owner should be involved in prioritizing the work within the sprint backlog.
