Efficiency
Efficiency is often referred to as "doing things right" In this chapter, we define efficiency in general terms as the ratio of output to input. In other words, a firm is more efficient when it produces more with the same amount of resources, produces the same amount of output with a lesser investment of resource, or - even better - produces more output with less input. The firm achieves efficiency improvements by reducing resource waste while maximizing productivity.
