In a software project, the product owner and development team agreed on a sprint backlog where the top priority is a payment module. The team worked on it during the first half of the sprint, but two developers now want to spend the remainder refactoring another feature that may cause future issues. What should the project manager do?

The correct approach is to remind the developers of the importance of focusing on and meeting the sprint goal. In Scrum, the sprint backlog is a commitment to deliver specific functionality that contributes to the sprint goal. Deviating from this agreed-upon work mid-sprint undermines the team's commitment and predictability. While refactoring is valuable, it should be prioritized and planned during sprint planning or as a backlog item for a future sprint, not spontaneously introduced. Allowing the refactoring would compromise the sprint goal. Escalating to functional managers is an overreaction and bypasses the team's self-organizing principles. Praising them for being proactive is inappropriate as it encourages deviation from the sprint commitment.
