Using the Visio Process Repository
There is also a Visio Process Repository, which is a site template that is included with Microsoft SharePoint 2013. It provides a place to share and collaborate on process diagrams, and for reviewers to add comments. The repository has built-in file access control and version control — users can view the process diagram simultaneously and edit the diagram without corrupting the original.
This repository can therefore ensure that a user is editing the most recent version of a process diagram, and enable a user to find out about updates that have been made to processes of interest to them.
In addition, administrators can monitor whether diagrams comply with a business's internal standards, or not, or discover, for example, which processes apply to a specified department. The Validation status of the diagram is automatically updated in the Process Repository when the diagram is saved back to SharePoint.
