First off, I think the idea is good. Like someone else said, a modern version of a sign in the window, that no driver that i know of has ever been fired for stop completing a stop where they see a sign and don't walk into office. Second, with the new technology, there's a lot of things we are able to do. Every district used to have a tracing dept. In my old district they had about 30 clerks working tracing a relatively small handful of pkgs. Now, people can do it themselves, Every district approx 60*30 clks = 1800 people saved. By using technology, we used to have a data dept with about 40 clrks keyentering billing records. Now none, savings 60*40 - 2400 people. Also, with the DWS machines we are able to bill customers for OS without a clrk measuring each pkg. Huge savings and huge revenue. Next year we are going to Dim Wt on grd pkgs too, which should increase revenue. Dell computer gets notices within minutes sent to them when a pkg is refused, nss, ns# etc. They contact customer before us returning pkg to them so they can save the sale. This technology lets us have the Dell volume. Again, what I have mentioned is just the tip of the iceberg when it comes to what technology has done for us.
I like the original posters idea of text messaging. Sounds like a great idea. It's really something UPS should have via worldship to send msg to pickup driver.
