Specify dependencies to indicate that certain tasks are required to be completed before other tasks can begin.
If a given task has dependencies, it will appear grayed out and inactive when running the checklist until all of the dependent tasks are completed. With dependencies, you can:
To configure dependent tasks:
Open a checklist from your library
Click Edit
Select a task from the left pane
In the right pane, go to the Dependencies
tab
Select one or more tasks that must be completed before the current task can be started. You will only be able to select tasks that are listed before the current task in the checklist.
