We went from a pod and rail to a cnc router. Just material jockeying, is amazing, the $ saved, wow ! But, and big but---- we were cutting on a slider and no, the ptp was not downloadable. and with no beam saw we could never stack cut and gain the speed.
The cnc router is screen to machine. Honestly, the software is the king and the solution.
As per the 1k a kitchen savings ? Ya, just for the fact, it all comes off the cnc, we draw it, it cuts it. The guides are not figured out yet, but jigs make it fly on face frame jobs.
Commercial casework stands up daily. We finally bought an auto dowel machine to punch the holes and load the dowels to keep up.
As per methods for the OP. I would expect with a good shop lay out and well trained guys, manual cut, a medium sized kitchen four guys- cabinets standing and all door blanks ready to glue up- day 1. Doors built and sanded day 2. Casework stained and completely ready to ship on day 4.
All considering cut lists, guides, hinges, etc all in and lists all worked out, period.
Profiles decided, all of it. No questions asked. Able to work uninhibited. Dedicated machines, jigs in place. Spray booth clean and ready.

We work it all out on paper now, even the complicated crap and it flies out the doors.
Can you time and expect excellent results in manual shops, yes.
