The Tagging feature can be used to categorise and restrict access to groups of SOPs.
The Approval Process feature enables you to prevent documents from going live until they have been approved by the appropriate personnel. When set up, approvers receive notifications and emails advising them that a document requires assessment for approval / rejection. This feature is essential for organisations operating a formal Quality System.
Tags are useful by themselves but are almost essential when the approval process is enabled, as they enable custom approval workflows to be set up for different types of tagged documents.
CONGRATULATIONS - THAT'S YOU ALL SET UP!
