![]() Often the proper course is to account for the risk in the project's contingency reserve. There are a variety of quantitative risk analysis and modeling Techniques that can used to produce the probability and cost figures.Īs a project manager, you may apply different techniques to minimize risk. The difficulty here is knowing how to produce reliable risk metrics, and what do do with the output of the EMV formula. ![]() There is a lot more to quantifying and qualifying your risk assessments than computing this formula. Risk #5 opportunity of 1,000 probability = 0.7 | EMV = $700 So the total EMV of the project is now $495,000. Risk #1: Your lead programmer will be poached. In more recent years the Latin Hyper Cube has also seen some use.Īssuming you've quantified your risks lets look at an example of how this would be applied.Īssume the project's total cost (aka cost baseline)is $500,000. In 1981 the Generalised Point Estimation Method was developed by RosenBleuth and can be used to calculate mean and standard deviation. The Monte Carlo method uses random and pseudo-random numbers to obtain the distribution of an unknown probability. This stochastic simulation was developed in 1947 by John Von Newman and Stanislew Ulam to approximate the highly random output of neutron diffusion. It is assumed that any project with a positive EMV is worth doing.Ī note on randomness: Iterative simulations can be performed with a "Monte Carlo" method. It is best to begin by listing them in the risk register with its cause and effect.Ī risk probability and impact matrix can help you gauge their signifigance. These sums are them added to the project cost to calculate total EMV. The formula is expesssed as EMV = (Probability) x (Impact) Multiply the values produced by step 1 and step 2. ![]() Assign monetary value of the impact of the risk when it occurs.ģ. Assign a probability of occurrence for the risk.Ģ. Note: generally the opportunities will be expressed as positive values and threats as negative values.ġ. This is calculated in dollars because we are using probability to determine value, not vice versa. Under the assumptiuon that those values are accurate this formula is used to select options among courses of action aka quantitatively prioritize a risk within a set of known risks. ![]() This is crusial since it is used in risk management.Īs the project manager it's your responsibility to determine and constantly recheck those values. It's only weakness is in having accurate impact and risk values. If that sounds like a simple one step calculation, that's because it is. The Estimated Monetary Value (EMV) formula is probabilty multiplied by impact.
