To cater for the situations where variability in a parameter will be significant in determining the confidence of meeting performance targets for a process, the model must allow a probability distribution to be entered for the parameter. The probability distribution for a performance parameter shall, as a minimum, be defined by; • the values of the minimum, maximum, mean and mode of the distribution, • the 'shape factor' (i.e. spread of the distribution – e.g. standard deviation), In cases where the variability in the parameter will not be significant in determining the confidence of meeting performance targets the model shall use a mean value only.
