Final answer:
Efficiency addresses the means by which resources are used, aiming for minimal waste, while effectiveness focuses on the attainment of goals. The correct pairing for the provided fill-in-the-blank question is B) efficiency; effectiveness.
Step-by-step explanation:
Whereas efficiency is concerned with the means of getting things done, effectiveness is concerned with the ends, or attainment of organizational goals. So, the correct answer would be B) efficiency; effectiveness. Efficiency refers to how well resources are used to achieve a certain output, such as producing goods or providing services. It's a measure of the input of energy to do work, with a focus on minimizing waste of resources. Effectiveness, on the other hand, is about achieving the desired or intended result; it is goal-oriented and concentrates on the ability to reach objectives or targets. Both concepts are important in understanding organizational performance and productivity.
