A team member is consistently late to the daily standup. What should the project manager do?

The most effective approach is to speak with the team member directly. This allows the project manager to understand the reason for the tardiness, reiterate the importance of the standup, and reinforce team ground rules in a private, constructive manner. This direct communication respects the individual while addressing the issue. Moving the meeting to the end of the day is a reactive solution that doesn't address the root cause and may inconvenience other team members who are punctual. Reinstating ground rules with the whole team might be perceived as passive-aggressive and doesn't target the specific individual needing the reminder. Ignoring the issue is detrimental to team morale and discipline, as it signals that ground rules are not enforced, potentially leading to further non-compliance from others, even if the individual is meeting deliverables.
