Tony,
This is what I do:
I try to structure my delivery area so that my furthest run is 8 minutes from the store. Of course, each delivery area is a little different and you might have some spots that are a little further. You’ve got to make a decision on whether or not it’s worth it to pick those areas up. In my case, I’ve got a row of barracks that are 14 minutes away from the store but those barracks make up about 25% of my total business so, of course I’ll make that sacrifice.
Avg. out the door times will differ based on your call volume and number of drivers you keep on staff. Drivers are scheduled to average 3 runs per hour at my store. Most stores, however, can have drivers comfortably average 4 deliveries per hour. If you stay within ideal scheduling standards on an average shift and have pizzas consistently out the oven in 12-15 minutes, there should be no reason your drivers can’t average 30 minute deliveries the majority of the time. Hope this helps. -J_r0kk
