While managing a project with a hybrid approach, the project manager notices excessive rework from quality issues, causing features to take longer than estimated. What should the project manager do to address this?

In a hybrid project, especially with quality issues causing rework and delays, the most effective immediate action is to address these problems within the agile framework. Raising and addressing quality and rework during the next sprint planning meeting allows the team to collaboratively identify root causes, adjust priorities, refine definitions of done, and incorporate quality improvements into upcoming work. This proactive approach leverages agile principles to solve problems quickly and iteratively. Extending milestones or submitting a change request to extend the project finish date are reactive measures that don't address the underlying quality problem. Escalating to the sponsor is premature; the project manager should first attempt to resolve operational issues within the team's control.
