…we had to load the vans ourselves and put together our own delivery list. If there was an app which could sort all that out I’d happily pay for it out of my wages…
That ^^
My workplace spent a small fortune on a programme, with support, that would optimise our routes according to time windows, traffic patterns and even weather forecasts. It was an unmitigated disaster! We were getting 25-30% less work done using the system as it didn’t know where the actual drop-off point was and would randomly send you on a detour to a customer in the sticks then back to where you were half an hour ago.
No computer programme can account for local knowledge, personal ways of working and the fact that the delivery entrance might not be at the front of the building.
