The Assignment Board is a simple yet effective way to manage your resources by task. This feature allows you to view all of your resources on a project and to move task tiles to any available resource shown. As it is a very simplified view, you are able to easily move any of the tasks to any available resource. However in being such a simple feature, it only allows you to move the task tile to the task owner, and not other resources to a single task. To edit non-Task owner resources on the task you have to open and edit the task itself.
Don't See the Assignment Board Option?
The Assignent Board, also referred to as a Kanban, is defaulted to be visible under the Resources view of a project. If you don't see the Assignment Board, check to see if it's been installed with Project Methodologies under Your Add-ons in the Administration section. When installed, you can configure the option to enable the Assignment Board to be visible or not to appear when unchecked.
