It was the "traditional" pipeline and to be honest only good for the "publisher" and some big enough studio, but really aren't that good for those job hunting game devs(and part of the churn and burn culture, can't and won't trying to form union if your turn over is high.)

It is how you get broken games every new release cause the guys that sticks around as supervisor didn't actually code the previous games or know the actual workflow/pipeline that makes the last game(their last touching code/software might be like 10+ years ago), the middle leads etc might have burned out during last crunch and go to next company after their vacation because fuck this crunch thing I have a family, then then newbies wearing shiny shipped game under their belt move to next company for a better position/pay. So no one or very few actually knows how last time things were done and may or may not have a voice during decision making. Every game, you build the team almost ground up and thus, make similar and more mistakes with ever increasing pressure from schedule and scale.

It's not an healthy cycle, it is something that creative industry should break away from.
