A documentation audit found the latest project schedule was a month old, even though the project manager knew it had been updated recently. How should the project manager have maintained project documentation?

The correct answer is keeping documentation in the Project Management Information System (PMIS) and sharing it with appropriate stakeholders. A PMIS is a centralized system designed to store, manage, and retrieve project documents, ensuring that all stakeholders have access to the most current versions. This prevents discrepancies like an outdated schedule being found during an audit. Regularly updating the project management plan is good practice, but without a centralized system like a PMIS, it doesn't guarantee that the latest version is accessible to everyone. Assigning a team member to keep documentation current is a task delegation, but it doesn't address the system for storage and access. Reviewing the risk register is a reactive measure for an identified issue, not a proactive method for maintaining documentation.
