Risk Impact calculates the quantitative cost and schedule impact of a risk. A risk value method is used to determine the risk impact for both cost and schedule.

The risk methods are:

  • Expected Value

  • Project Evaluation and Review Technique (PERT)

  • Triangular PDF

Expected Value

This method determines the value that a risk will contribute to the overall Portfolio Risk value based on the impact value and the probability of occurrence.

PERT

This is an industry standard method to determine the normalized value that a risk will contribute to the overall Portfolio Risk value based on the weighted values (inputs for low, high, and likely) and the probability of occurrence.

Triangular PDF

This is an industry standard method to determine the value that a risk will contribute to the overall Portfolio Risk value. This method uses the value for a specific confidence level on the probability density function for a triangular distribution (inputs for low, high, and likely) and the probability of occurrence.

The risk impact value is positive for threats and negative for opportunities. The user input fields are set to mandatory based on the method selected.

Based on the selected Quantitative Analysis Method the Risk allocation varies.

For Risk Level Quantitative Analysis Method, the Risk is allocated only for the Portfolio level item.

For Detail Level Quantitative Analysis Method, the Risk can be allocated to all the Projects under selected Portfolio.
