Cost—benefit analysis CBA , sometimes also called benefit—cost analysis , is a systematic approach to estimating the strengths and weaknesses of alternatives used to determine options which provide the best approach to achieving benefits while preserving savings for example, in transactions, activities, and functional business requirements.

These projects may be dams and highways or can be training programs and health care systems. The idea of this economic accounting originated with Jules Dupuit, a French engineer whose article is still worth reading. This act required that the U.

Formally defined, economic analysis is the monetary evaluation of alternatives for meeting a given objective. For example, to meet the need for additional office space a decision maker might consider new construction, renovating an existing facility, or leasing another building. The evaluation is based on a comparison of discounted costs and benefits over a fixed time period of time. Alternatives can be summarized in terms of the ratio of total benefits to total cost benefit-cost ratio or equivalently, the total net benefits net present value. Economic analysis has been integrated into the decision making process of most if not all U. Building owners use economic analysis to determine the most economically efficient or cost-effective choice among building alternatives. The steps to estimate the economic consequences of a decision, as listed in Ruegg's and Marshall's Building Economics—Theory and Practice , are summarized below:.

It is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components. System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives. It is a problem solving technique that improves the system and ensures that all the components of the system work efficiently to accomplish their purpose.

Organizations rely on cost benefit analysis to support decision making because it provides an agnostic, evidence-based view of the issue being evaluated—without the influences of opinion, politics, or bias. By providing an unclouded view of the consequences of a decision, cost benefit analysis is an invaluable tool in developing business strategy, evaluating a new hire, or making resource allocation or purchase decisions. Origins of Cost Benefit Analysis The earliest evidence of the use of cost benefit analysis in business is associated with a French engineer, Jules Dupuit, who was also a self-taught economist.
