Development team members work across three time zones, making it hard to schedule a daily standup that suits everyone. What should the project manager do?

The best approach is to encourage frequent, small team meetings with two or three team members. This allows for necessary coordination and information sharing without forcing inconvenient schedules on everyone. Daily standups are valuable for quick synchronization, but their format can be adapted. Replacing the standup with a daily report loses the interactive benefit of direct communication. Letting team members decide if they want to join could lead to inconsistent attendance and a lack of shared understanding. Requiring all team members to join regardless of time zone is impractical and can lead to burnout and decreased morale, undermining the team's effectiveness.
