The project has an issue with a vendor known for poor quality. The project manager must ensure the quality problem is addressed. What should the project manager do first to begin resolving the issue?

The project manager should first review the risk register and follow the response strategy because this is the proactive and structured approach to issue resolution. A known vendor quality issue should ideally have been identified as a risk during planning, with a corresponding response strategy documented. This strategy would outline the pre-defined steps to mitigate or address the risk, ensuring a consistent and effective approach. Meeting with the vendor (A) is a potential action, but it should be guided by the established risk response. Engaging the test team (B) might be part of a solution, but it doesn't address the root cause or follow a structured process. Updating the risk register (D) is important, but it comes after reviewing the existing strategy and initiating actions, not as the first step to begin resolving the issue.
