I have seen ORION work extremely well, but it has one critical flaw. The loops have to be set up and traced well. The map data has to be pristine and each route must have parameters set correctly. The problem is none of this is static. It cannot be one and done. Won't work. To be successful, the data must be monitored, corrected and improved every day. No exceptions. If you have a good DMS who knows his or her job, ORION works great. The problem is that good DMS's are few and very far between. In retrospect, ORION was a huge waste of money because UPS failed to properly train key people and then hold them accountable. Drivers and customers end up paying the price.
