Project progress meetings are held via conference call. One team member repeatedly interrupts others, preventing them from finishing their points. What should the project manager do?

Reviewing ground rules, meeting objectives, and the agenda at the start of a meeting sets clear expectations for behavior and participation. This proactive approach reinforces professional conduct and can prevent disruptive behaviors, like interruptions, by reminding everyone of established norms for respectful communication. Speaking privately with the team member is a reactive measure that addresses the symptom but doesn't reinforce overall meeting etiquette for the group. Enforcing the agenda and time limits is good practice but doesn't directly address the interruption issue as effectively as a ground rules reminder. Speaking privately with non-participating team members addresses a different problem entirely.
