P-man,
The flaw...is in the underlying assumption that the fastest and most efficient path to travel a on a given route is always the shortest.
We have drivers who have been instructed to drive out to and back from their delivery area via surface streets instead of taking the freeway or other major arterial roads. They are forced to cut through residential areas and wait at multiple stoplights. Would you agree that it takes less time to drive 20 miles on the freeway nonstop at 55mph than it does to drive 17.2 miles on congested surface streets at 35MPH with 15 stoplights to wade through? Any rational person would, but ORION doesnt. These drivers have seen an increase in idle time and paid day, and a decrease in SPORH, but none of that matters any more; in typical UPS fashion we care nothing about real-world results and everything about chasing a compliance metric.
Another flaw with ORION is the assumptions that it makes about how long it will take the driver to complete a given set of deliveries or pickups when it decides to have him break trace in order to meet some sort of a commit time. Lets say the driver has four Next Day Air stops for an office building that ORION is telling him to break trace for. If each one of the stops is for a different office on a different floor that will involve multiple waits for an elevator, he may need to arrive at that building as early as 10:10 in order to give himself time to find parking and make service on every stop prior to 10:30. If, on the other hand, all four stops are on the ground floor right next to a loading zone, he may very well be able to arrive at 10:25, which will allow him to complete the deliveries in an area instead of obeying ORION, breaking trace, and returning to that area later. Unfortunately.....the driver who uses common sense and area knowledge to make smart decisions will not be rewarded for his actions but will instead be reprimanded for failing to generate the 85% compliance metric.
There are countless other examples of situations where a driver with area knowledge and the ability to make live, firsthand observations of real-world load and traffic conditions will trump a system that is based solely upon GPS coordinates. What I am seeing is that ORION is, at best, a glorified version of EDD that might be of some value to a driver with no area knowledge but no real help at all to a driver like myself with 20 years of area knowledge. And any gains in productivity that might be realized through the intelligent and judicious use of ORION will be completely negated by the stupid and counterproductive choices we will be forced to make in order to chase a meaningless 85% compliance metric.
