What is a project risk mitigation step a test manager might take?

The correct choice focuses on the proactive approach of arranging a back-up test environment in case the current one fails. This step directly addresses potential risks related to the testing environment, which is critical for executing tests reliably. By establishing a back-up test environment, the test manager ensures that testing can continue uninterrupted, even if the primary environment encounters issues. This kind of risk mitigation strategy helps avoid delays in the testing schedule, protects the project timeline, and supports overall project success.

In the context of risk management, this approach emphasizes the importance of planning for unforeseen circumstances that could impact testing activities. By having a contingency plan in place, the team can respond swiftly to disruptions, maintaining the integrity and reliability of the testing process.

The other options, while relevant to various aspects of testing and project management, do not specifically represent steps taken to mitigate risks associated with the continuity of testing activities. Testing for performance problems is more about identifying issues rather than preemptively managing risks; hiring a contractor addresses a staffing gap but does not specifically mitigate risks associated with the test environment; and performing a project retrospective meeting focuses on reflection and learning rather than directly managing project risks in a proactive manner.
