It's a very high-level view of how manufacturing works to just blindly say "Modern production doesn't allow for mistakes". Trust me, it does. Coordinating multiple teams from multiple plants causes colossal errors.
Even Airbus isn't immune. Germany and France were using different service packs of their solid modelling software which used different K-factors for cable routing. Guess what happened when they put the first A380 together?
As I have said multiple times (I'm tired.), the changes are being made soon, and it takes time to bring these other facilities online with this project. These changes were just recently decided and they can't just INSTANTLY start totally reworking their production schedules, get jigs ready, order material etc... It is a 6 month rolling wave.
