A key stakeholder on a construction project is spending excessive time on site and interrupting the team's work. What should the project manager do?

The most effective approach is to understand the stakeholder's concerns and integrate feedback into regular reports. This addresses the root cause of their behavior (likely anxiety or a need for information) proactively and through established communication channels, minimizing disruption. Scheduling an ad hoc meeting might be seen as reactive and could further disrupt the team. Reassuring the stakeholder without understanding their concerns is a temporary fix and doesn't address the underlying issue. Escalating to the sponsor should be a last resort, as it bypasses direct communication and can damage the relationship with the stakeholder.
