The users have to learn the various formulas, such as =Rand(), Vlookup, COUNTIF, NORMINV(rand(),mu,sigma) for normal random variable, NORMINV(p, mu, sigma) for normal random varianve with a mean and a standard deviation. Finally, they have to learn the usage of the confidence interval for mean profit by using the formula listed below:
Mean Profit +- 1.96 * profitstd.dev / number iterations
To learn all the steps and apply the formulas require the existing and new staff to be enrolled in training sessions to be able to utilize the product appropriately.
