A task status workflow has a particular property. It's a workflow that can be applied to the task of another workflow. It provides different statuses for that task, letting users know the progress of that task.
To find out how to link a task status workflow to a task—see Task Setup Options.
In the Basic Task Status workflow (a workflow that comes with Producer) there are seven possible options (Standby, Pending, Need Assistance, In Progress, To Validate, Revise, Approved).
In the Production or Assets > Manage tab, when a user clicks on a task status, a drop-down menu lets them choose or update the status of that task from an option in the list.
