During kickoff, a stakeholder responsible for key information shows low participation and believes the project offers no benefit. The project manager sees this as a major project risk. What should the project manager do?

The project manager should facilitate a supportive level of engagement for this stakeholder. This directly addresses the root cause of the problem: the stakeholder's low participation and lack of perceived benefit. By actively engaging them, understanding their concerns, and demonstrating the project's value to their interests, the project manager can transform a potential obstacle into an ally, thereby mitigating the risk. Asking the project sponsor for advice might be a later step if engagement fails, but the initial focus should be on direct stakeholder management. Considering a different stakeholder is not ideal if this person holds key information. Performing a qualitative risk analysis is a good general practice, but it doesn't resolve the underlying stakeholder issue. Simply ensuring accuracy and monitoring doesn't proactively address the lack of engagement or perceived benefit.
