Check out this fascinating radio piece on the efforts of UPS to manage driver productivity. Sensors throughout the vehicle produce information that's "about as important as the package for us," says Jack Levis, who's in charge of onboard data collection and analysis.
The piece has the usual Big Brother tropes, but it also delves into the company's ROI for investing in technology that can save time for the driver. A driver who says he used to deliver 90 packages a day now handles roughly 120. Levis says, "Just one minute per driver per day over the course of a year adds up to $14.5 million."
