To improve package delivery, one change UPS made involved improvements in how

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 change implemented is not an example of technological change because it did
not require the use of new machinery or equipment.
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.

number of inputs (trucks and drivers). Therefore, UPS has implemented a positive
technological change.
D) The scenario described is an example of management efficiency and not
technological change. Essentially, the chain changes its way of operating its business.
