Cue to Cue makes sense to me in productions where the settlement must be handed over to others after the run. In particular, the new features that make it possible to work on the same document, in this way changes in both manuscript and cue can be updated all around. It also opens up a more common understanding of the individual elements of a performance. Bonus must also be that from the beginning you make a complete production documentation for next year's reenactment of the show.
