To improve package delivery, one change UPS made involved improvements in how packages were routed. The firm started using more detailed maps to plan the routes for packages

As a result, the typical delivery driver could travel several miles less per day while delivering more packages. Which of the following statements best describes this change at UPS? A) The firm is able to produce more output (deliver more packages) using the same number of inputs (trucks and drivers). Therefore, UPS has implemented a positive technological change. B) Technological change refers only to the introduction of new products or improvements to existing products. As such, the scenario described in the question is not technological change. C) The change implemented is not an example of technological change because it did not require the use of new machinery or equipment. D) The scenario described is an example of management efficiency and not technological change. Essentially, the chain changed its way of operating its business.
