A project manager in one country reports to a lead project manager in another country. The lead PM repeatedly demands updates and uses multiple communication channels if the project manager does not respond within minutes. Both are equal in seniority and report to the same functional manager. How should the project manager proceed?

The best approach is to negotiate directly with the lead project manager. This proactive communication addresses the issue at its source, fostering collaboration and finding a solution that respects both parties' needs and working styles. Since they are of equal seniority, a direct negotiation is appropriate before escalation. Referring the lead PM to the communications management plan might be perceived as confrontational and doesn't address the underlying behavioral issue. Updating the plans unilaterally won't solve the immediate communication problem with the lead PM. Escalating to the functional manager should be a last resort, as it bypasses direct problem-solving and could damage the working relationship.
