The way the delivery allowance works is you get a per stop allowance (based on the delivery area number, like 5213) for the stop, with the biggest impact on this number being the walks observed in that area. That's why when drivers would tell me their allowance should change because it's 5 years old, I would ask facetiously if the houses got any further away from the street. I thought I was being witty but I stopped doing that because the guy who just did 160 stops while I sat in the A/C usually didn't think it was funny.
Then, added to this, is a per piece allowance which originally was .00512 hours / pkg, (meaning you could record about 200 packages per hour. NOT deliver them, just record them). This was the allowance back when everyone was on paper. Now consider the true pace of the change to where we are now. In UPS terms, it was glacial. First we got DIAD I, which really only did away with the paper. Back then, there were only tracking labels on airs and the occasional Groundtrac, so scanning wasn't so common. When we did scan, it was a 10 digit barcode where we still had to record the shipper number manually after we scanned the package.
Through the 90's, little by little packages with barcodes became more and more common, and the 1Z was introduced with the shipper number imbedded in the track number. It wasn't until '98 or so that I saw corp numbers showing that 98.5% of packages had readable barcodes on them. This process took 10 years. ALL this time, as 1Z labels became more and more common, we technically should have been sampling the volume and decreasing the per piece recording allowance little by little. But we didn't. Finally, we found ourselves in 2003 or 2004 with 90% or better of our packages having 1Z's that require no shipper number recording, just the OCA packages still have the 10-digit numbers. And recording the address now usually just entails the street number and the first four letters of the street name more than 99% of the time.
In a strictly engineering sense, we've come a long way in package recording from the paper sheets, but had never addressed the per piece allowance. The new allowance of .00344 hours / pc (I might be off by a couple of 10-thousandths, I don't have CRS at home) now means the average driver should be able to record about 280 packages per hour. The average driver with ~280 delivery packages loses about 25 minutes of planned time all in one change, but really, the allowance should have been changing little by little all along. The fictional driver with 100 stops, should have increased to 101 2 years later, then 104 3 years after that, etc. based on the delivery allowance alone. But as I said, this change was very slow. How much did all the other factors affect the driving job in the meantime? The increase in QVC and HSN as internet shopping exploded. Those enormous Dell packages in the late 90's. Against this backdrop the slow, steady change in average delivery recording time would have hardly been noticeable, like a tide rising, but it was there.
As engineers, it's our job to study the activity and come up with the right number. In a strict engineering sense, the right number is the right number no matter what the consequences of that adjustment are. Our function as engineers is to have the correct standard, no more, no less.
JustTired, I can't promise you that when that number was discussed in the hallowed halls of Glenlake Pkwy, some finance guy didn't do the Mr. Burns finger thing in his office and figure out we'd save cost in bonus centers. I'm sure they did. That's THEIR job.
But the allowance is based on actual drivers studied recording actual packages in thousands of instances and was changed based on the results of that study, which was honest. That's a whole lot different then a bunch of guys getting together in a smoke filled backroom, plotting to reduce that number by x percent, and then inventing the justification. I can't prove it, but I don't believe we do things that way. I understand how it can feel that way, even, but that's just not the way I believe it is.
