Great and Small:

So, Vader takes an Agile approach.  He prioritizes the features list (“Look, we really need the big laser thing; our customers will just have to come to us at first.”), and he works in vertical slices.  At the end of the movie, it seems to have paid off.  There are still huge pieces missing and construction is nowhere near complete, but “Those weapon systems are operational!”

Funny. And somewhat true.
