PMP Practice: Implement Resolution Strategies

Andrés Maldonado-Blanco is managing an agile mobile gaming project at Rogue Pelican Media.

The team's velocity has remained stable, but three team members have privately complained to Dante that they feel their input is being ignored. The product owner supports faster iteration but has not taken a position on the working agreement breach. What should Dante do to address this conflict?
