The document discusses the importance of engineering economy in decision making for individuals, businesses, and government agencies. Engineering economy provides quantitative analysis techniques to evaluate and compare the costs and benefits of project alternatives over time. It helps structure the estimates needed to evaluate alternatives and select the most economically favorable option based on metrics like present worth, rate of return, and benefit-cost ratio.
