Input
mu = mean value (expected value) and sigma = standard deviation in days, hours, minutes, seconds (all in the 0000:00:00:00 format)
As duration, a value in line with the logarithmic normal distribution is determined for each process instance.
Example
If you specify one hour as the mean value of a function's processing time and one hour as standard deviation, all processing times of the function will range between one and three hours with a 66% probability. The probability of the function's processing time being greater than three hours is higher than the probability of the function's processing time being less than one hour.
