Suppose I have 3 scientific projects running at the same time with it's own tasks.
At certain point some lab tests should have been done at the same place alltogether (in order to reduce costs). They don't have a specific order from the start of the project but they do need to be done before reaching that point.

When they are done, that task is finished, for all of them, at the same time...

To me, in this problem, this looks like the most natural way to follow the project flow path.
Maybe I am missing something.

I understand the philosophy behind GTD, and I do believe one must do the best effort to keep that set of mind in order to accomplish. But I don't expect it to be strictly rigid nor perfect...
