Our solution expects to mitigate 80% of the issues, so we can set the Estimated Risk Mitigation to 0.8. Given 100 the above mentioned costs (Cost of the Solution) per year, and 60 the cost of each manual review dataloss (SLE) occurring 5 times a year (ARO) with an Estimated Potential Loss (ALE)= (ARO*SLE) = (5 * 60), the ROSI can be calculated as follows:
