Quoted from MrMikeman:
If they were able to pre-build certain parts (like cabs, PF, etc) they may be able to produce more than 50/week.
You can stock pile assemblies but only so much due to space - so any 'head start' would be pretty limited. And while prebuilding more stuff than before would allow them to shift work, it can't change your throughput in other areas. Simple example... if they can only QA 20 games a day, it doesn't matter how many assemblies are on the shelf or how much is in the queue.. they are only going to finish 20 games a day.
Production like this is highly scheduled because of the differences in times each stage may take so you don't get these backups or droughts. Things that take longer you stage ahead (Playfields, cabinets, etc). You don't overproduce what you can't advance to the next stage, etc. So the funnel of parts being on hand, sub-assemblies ready, the throughput of each stage etc is highly orchestrated to keep the line moving steadily. And usually there are stages that are difficult bottlenecks that are hard to scale. It can be as simple as how many loading docks you have and how quickly you can turn trucks around.
CGC has never shown the posture of 'now lets speed up' for temporary anything - Let's just hope for a steady reliable stream of quality games.
