Cost-benefit analysis

Welcome, everyone. Today we will be exploring cost benefit analysis or CBA, a key tool in business, economics, engineering, public policy, and risk management. CBA systematically compares the advantages or benefits and disadvantages or costs of any proposed action, project, or policy. It creates a logical framework for decision making, helping organizations and governments determine if an initiative is worthwhile, or if resources could be used more effectively. In the United Kingdom and United States of America, CBA is central to business cases, infrastructure planning and regulatory evaluation. The first step in CBA is to clearly define the project, policy, or change under consideration. Next, all relevant costs and benefits must be identified, including direct costs like materials and labor and indirect or intangible costs such as reputational risks or environmental impacts. On the benefits side, all advantages are estimated, financial gains, productivity improvements, safety enhancements, and social or environmental impacts. These elements are quantified, often converted to monetary values to enable comparison. The process should always be transparent and evidence based. Although cost benefit analysis is powerful, it faces notable challenges. Valuing intangible or long term benefits such as improved safety culture or reduced environmental harm is complex and sometimes contentious, especially when assigning monetary value to human life,
