How do you determine the size of a task's contribution when determining a risk factor?
What impact does a small-step function D from a task typically have on determining the risk factor for its task stream?
What impact does a large step-function D from a task generally have on determining the risk factor for its task stream?
How does a task leader keep track of the possible ways of mitigating or reducing risks that he or she uncovers while doing risk analysis?
How much smaller than the total of adding all the critical path Ds together would you expect the risk factor to typically be? Why?
