L'analyse coût-bénéfice (ACB) est un outil puissant utilisé en estimation et contrôle des coûts pour guider la prise de décision. Essentiellement, elle implique de peser les avantages potentiels d'un projet, d'un plan ou d'une action contre ses coûts associés. Le résultat est souvent exprimé sous forme de ratio, comparant la valeur des avantages au coût de leur réalisation.

Scenario:
Your company is considering investing in a new software system to automate a manual process. The software costs $100,000 and is expected to save $20,000 in annual operating costs. The software's lifespan is estimated at 5 years.
Task:
**1. Total Benefits:** * Annual savings: $20,000 * Lifespan: 5 years * Total benefits: $20,000 * 5 = $100,000 **2. CBA:** * Total benefits: $100,000 * Initial Investment: $100,000 * CBA: $100,000 / $100,000 = 1 **3. Recommendation:** * The CBA shows a ratio of 1, indicating that the total benefits equal the initial investment cost. * This suggests that the software system is likely to break even over its lifespan, but it may not offer a significant return on investment. * Further considerations, like potential intangible benefits or alternative solutions, should be analyzed before making a final decision.
