Forrester risk-adjusts cost and benefit estimates to better reflect the level of uncertainty that exists in real-life business scenarios but not necessarily captured in traditional business cases. If a risk-adjusted ROI still demonstrates a compelling business case, it raises confidence that the investment is likely to succeed because the risks that threaten the project have been taken into consideration and quantified. In general, risks affect costs by raising the original estimates, and they affect benefits by reducing the original estimates.
