Tutorial Step 12: Assign Resources
You can assign resources to tasks from task view or from resource view.
In task view, you can select the task and then use the Task Assignments inspector to select which resources should be assigned to it.
Or you can just pop open the menu on the Assignment button in the toolbar.
In resource view, you can assign a task by dragging it from the Unassigned timeline into a resource's timeline.
Use the Task Assignments inspector to assign multiple resources to a task and change its duration. For example, unloading boxes gets easier when more people help, so that task should get shorter when more resources are assigned. For these situation, the effort is considered fixed. However, showing an educational video takes the same amount of time no matter how many people attend; for that kind of task the duration is fixed, so you should choose to keep the duration fixed for this kind of work. (Of course, you can also fix both.)
