A project manager in one country is reporting to a lead project manager for a new software development project in another country. The lead project manager constantly requests updates from the project manager, often demanding information via multiple communication channels if the project manager does not respond within a few minutes of a request. Both of them are equal in seniority and both report to the same functional manager. How should the project manager proceed? Refer the lead project manager to the communications management plan. Escalate the issue to the functional manager and explain the situation to them. Negotiate a mutually agreeable feedback cycle with acceptable timelines. Update the communications management plan and the stakeholder engagement plan
