When a project manager identifies that the response action for an issue is insufficient, it is crucial to take immediate action to prevent further complications. The best course of action in this scenario is to meet with the project team to find another solution1. This approach ensures that all team members are aware of the issue and can contribute their expertise and ideas to resolving it. It also promotes transparency and collaboration within the team1. The other options (A, B, C) are also important steps in issue management, but they are not the immediate next steps when a response action has proven to be insufficient2. References: 12
