Claim: Quantitative risk assessment software (includes single-loss expectancy which is the monetary value expected from the occurrence of a risk) must be used in isolation and some software can only be used in certain organizations.
Evidence: In financial terms, quantitative risk assessments include a calculation of the single loss expectancy of monetary value of an asset. Single-loss expectancy (SLE) is the monetary value expected from the occurrence of a risk on an asset. Some of the QRA software models described above must be used in isolation: for example the results from a consequence model cannot be used directly in a risk model. Some of the software is proprietary and can only be used within certain organisations.
