You can make your process diagrams available for collaboration and quick updating by saving them to a process repository in SharePoint 2010. A Visio Process Repository is a site that contains a type of document library that provides check-in and check-out functionality and supports versioning for Visio diagrams. The document library includes columns that display validation status and cross-functional flowchart headings.
Before you can save to a process repository, the repository must be added to the list of SharePoint sites that are recognized on your computer. This might be done for you by an administrator. However, if the option to save a diagram to a process repository is not available, follow these steps.

Use your browser to visit the SharePoint process repository page.
In the Processes document library, click Connect to Office, and then click Add to My Sites.
