Yes we did, but most often you could just look at the delivery map and see what deliveries would go together. Optimization won't tell you which orders were not complete (waiting on an item that needed to be remade or was made wrong, etc.) and many times just eyeing the map and knowing the delivery area was all that was needed. Drivers also knew which shortcuts would be beneficial to use that the optimization would not know. The software at the time also would not be able to factor current traffic in the equation. It's been a while, maybe they do now, I don't know, I've left for greener pastures.
