Any Shopfloor Editor users?

I've been using SFE for about 2 years but only ever used to to edit individual modules/routines. I've noticed there's an option in it to configure a 'Factory', i've looked in the manual but i can't really get my head round what configuring a factory actually does and if it would be advantageous to me?? Can anyone enlighten me??

Cheers.
