Final answer:
True, companies should assess the sensitivity of results to assumptions when making a business case for an IT investment, employing sensitivity analysis to manage uncertainties.
Step-by-step explanation:
True, in making the business case for an IT investment, companies should definitely assess the sensitivity of results to the assumptions. This is because the benefits and costs projected in a business case depend on assumptions that can vary. For example, assumptions may include expected lifespan of the technology, maintenance costs, potential downtime, or productivity gains. Since there is an inherent uncertainty in projecting future outcomes, it is important to understand how small changes in these assumptions could impact the overall benefit of the investment. Sensitivity analysis can help in determining whether an investment is robust despite uncertainties, and is a critical practice in business decision-making processes. By performing sensitivity analysis, companies can anticipate possible changes in outcomes and prepare strategies to mitigate risk.
