To ensure effective document control, business leaders should adhere to the following best practices: 1. Version Control: Maintain a clear system for tracking document versions to prevent confusion and ensure that the most current information is used. 2. Access Control: Implement role-based access to restrict document access to authorized personnel only. 3. Backup and Recovery: Regularly back up documents and have a recovery plan in place to prevent data loss. 4. Metadata and Tagging: Use metadata and tagging to organize documents and facilitate easy retrieval.
