CBA, or Cost-Benefit Analysis, is a systematic approach used to evaluate the strengths and weaknesses of alternatives in decision-making. It involves comparing the total expected costs of a project or decision against the total expected benefits. This analysis helps individuals and organizations determine whether a particular course of action is worthwhile and aids in prioritizing projects based on their potential return on investment. In practice, CBA is commonly used in various fields, including economics, business, and public policy. By quantifying both costs and benefits, stakeholders can make informed choices that maximize positive outcomes while minimizing negative impacts.
