What if a task can or needs to be worked on in more than one stage?

Adjust the “When can this task start?” setting to include all stages where the task can be worked on.

In the example above, the drafting of the back translation must be completed in stage three.  If I want to allow the team to work on the back translation in any of the earlier stages, then I change the “When can this task start?” setting to “Any time.”
