Correct Answer: D
When faced with a significant testing backlog that is becoming a bottleneck, and the team has identified a tool that could resolve this issue, the project manager should take proactive steps to integrate this tool effectively.
Enrolling team members in training on the tool is a strategic move that equips the team with the necessary skills to use the new tool efficiently, thereby addressing the bottleneck. This approach aligns with the principles of Agile and Lean methodologies, which emphasize continuous improvement and the importance of equipping team members with the skills needed to adapt to changing project demands12.
References: The decision to enroll team members in training is supported by best practices in backlog management as discussed in Agile project management resources and the PMI-PBA guidelines, which advocate for enhancing team capabilities to improve productivity and project outcomes34.
