PMP Practice: Communicate project information and updates effectively

Diego Villanueva-Cruz is leading an agile team at Ikigai Automation developing a mobile meditation app. The team includes three developers, one UX designer, and a product owner who travels internationally for work. During the first sprint planning session, team members express confusion about when and how they should communicate with each other and with stakeholders.
