Summary table of risks The table below shows the risks that are included in the MC model, including their estimatedprobabilities, and cost and schedule impacts. A risk identifier (RI-ID)with a prefix RT denotes athreat, RO denotes an opportunity, and RU denotes a risk uncertainty. The cost and scheduleimpactshaveeitherone,twoor(usually)threevaluesdependingonwhetheritisa1-pointestimate(singlevalue),a2-pointestimate(i.e.aflatrangep.d.f.),ora3-pointestimate(i.e.atrianglep.d.f.).
