The project manager should first try to understand why the key stakeholder is not attending the meetings and providing false information. The project manager should discuss the communication needs and preferences of the key stakeholder and tailor the communication accordingly. This will help to build trust and rapport with the key stakeholder and ensure that they receive accurate and timely information about the project progress. Creating a new communication artifact, emailing the latest status report, or sharing the meeting recordings may not address the root cause of the problem and may not be effective in engaging the key stakeholder. References: PMBOK Guide, 6th edition, page 524; PMP Exam Content Outline, 2021, page 10.
