Quoted from Vdrums:
What JJP really needs is a second shift of workers. Keep that production line humming 16 hours a day (maybe one with new games and one with older titles - I think I read they have 2 production lines?
No, the have proven night shifts are never as productive as day. You only run night shifts if you need to keep equipment running 24/7 to maximize its output.
What JJP needs is to keep both lines busy everyday so they can keep a senior talented and trained workforce for years, that’s how they improve speed and build quality.
