When a new project manager encounters conflicting data on the product value, it’s crucial to consult the project reports from the previous project manager12. These reports provide a historical context and may shed light on the source of the conflict12. The new project manager should review these documents to understand the project’s history, including any issues that may have arisen and how they were addressed12. This will help the new project manager identify potential areas of concern and develop strategies to address them12. References:
