PMP Practice: Verify performance improvements

Bo-Wen Fang is leading a government infrastructure project to upgrade a city's water treatment facility using a traditional waterfall approach. The project has strict regulatory milestones that must be met sequentially, and all design documents require formal approval before construction can begin. During a performance review meeting, Bo-Wen notices that Joaquín Herrera-Bautista, a civil engineer on the team, has been completing his technical drawings ahead of schedule but rarely participates in team discussions. Two other engineers have privately mentioned they find Dante's solo work style frustrating because they need to coordinate their designs with his, but Dante submits everything at the last possible moment before formal reviews. The project is currently on track for its next regulatory checkpoint in six weeks. What approach should Bo-Wen take to provide feedback to Dante?
