Cost-Benefit Analysis

Cost-benefit analysis is a data analysis technique that compares the expected costs of an action or decision against its anticipated benefits to determine its financial viability and value.

Explanation

Cost-benefit analysis (CBA) is a systematic process for calculating and comparing the benefits and costs of a project, decision, or initiative. The goal is to determine whether the benefits outweigh the costs and by how much, providing a financial basis for decision-making. Common metrics used in CBA include net present value (NPV), return on investment (ROI), internal rate of return (IRR), and payback period.

In project management, CBA is frequently used during project selection, when evaluating change requests, and in quality management to determine whether the cost of quality improvement initiatives is justified by the expected benefits. It helps stakeholders understand the financial implications of decisions and prioritize investments that deliver the greatest value.

A thorough CBA considers both tangible and intangible benefits, as well as direct and indirect costs. It should also account for the time value of money and the risk associated with uncertain benefits or costs.

Key Points

  • Compares total expected costs against total expected benefits
  • Uses metrics like NPV, ROI, IRR, and payback period
  • Applied in project selection, change control, and quality planning
  • Should consider tangible and intangible factors, and the time value of money

Exam Tip

Cost-benefit analysis is the go-to technique when a question asks about justifying a project or quality improvement financially. Know the basic metrics: NPV, ROI, IRR, and payback period.
