Predecessors to Summary Tasks

A task can be delayed if any summary task of that task has a predecessor.

Select the summary of the delayed detail task and check for predecessors in the same way as explained above in 'Predecessors' section of this document. This also applies to the summary's summaries ("grandparents") as well, if they exist. Since this kind of task delay can be particularly hard to trace unless you remember to check for it, you might decide you'd rather always set dependencies to detail tasks, and never set dependencies to summary tasks.
