Workflow Approval is a Desygner Enterprise feature that allows administrators to approve designs before they are downloaded, shared or printed by members. It allows administrators to check content before it goes out and also for files to travel back & forth within the company.
To have a workflow approval, the admin has to define permissions for the templates on his end first. When a member wants to use their design, the admin is notified and is able to check the design and approve it or not. If they don't approve, they can send a message to the member telling them what needs to be fixed. The admin can also get into the member's design and make the changes themselves.
Under Workflow Approval is another feature called Task Manager, which allows for creatives to manage tasks within the Desygner system. It also allows for non-creative to make requests such as new templates, assets and to ask for help with their design.
