At what point does the development team freeze new additions to code to a module/update? It seems like it would be easy to continuously add to code scope and thus push live dates back. You have to come to a point where you say enough is enough. How do you get to that point? Is it predetermined before patch coding begins? Is it floating until someone arbitrarily says "That's it. . . no more?" Really curious about this (and for no hidden reasons--this is not bait).
