According to the PBA Guide, one of the key activities of the project manager is to ensure that all project information is captured, stored, and shared appropriately throughout the project life cycle1. This includes creating and maintaining a project repository or a document management system that can store all project deliverables, such as test reports, in a secure and accessible way2. By doing so, the project manager can prevent the loss of valuable information and facilitate knowledge transfer among the project team and stakeholders. The other options are not relevant or effective for this issue, as they do not address the root cause of the missing test reports. References:
