To access apps for your board click the hamburger menu on your board and go the App Store.
The defined workflow app allows you to apply a set of rules per column on a board in Favro. Once enabled, it gives on a per column basis the ability to define:
Whether cards can be created or committed in the column.
Which cards columns can be moved into on this board.
Which users can move cards from the column.
A Defined workflow is a powerful App that fits a wide range of scenarios for many different types of teams - from developers to office administrators.
For example, an office administration team might need to formally approve all vacation requests.
By allowing all members of staff to add vacation requests to the first column in the board and then locking down the Approvals column, they can ensure that all vacation requests are approved by those with the authority.
