1. Plot the six risks on a probability/impact matrix, using Figure 11-5 as a guide. Also assign a numeric value for the probability that a risk will occur and the impact of each risk on meeting the main project objectives. Use a scale of 1 to 10 to assign the values, with 1 representing the lowest value. For a simple risk factor calculation, multiply the probability score and the impact score. Add a column called Risk Score to your risk register to the right of the impact column. Enter the new data in the risk register. Write your rationale for how you determined the scores for one of the negative risks and one of the positive risks.
