Step 1: Identify a minimum of eight risks to the Aviation Technology project. Step 2: Use the Impact Scale in Figure 7.5 (or create your own scale) and plot the risks on a Risk Severity Matrix (like Figure 7.7). Step 3: Develop a Risk Response Matrix (like Figure 7.8). Step 4: Create a simple Change Request Form (like Figure 7.10). Time and Activity Estimates Charlie wants to use mathematical modeling to improve his schedule and to make it more realistic. He seeks input from the experts who will be working on the project because he wants to better understand the work and get their input into the activity duration. Charlie recognizes that sometimes the work is fast and there are no problems. Other times, activities have risk associated, which has an impact on the duration. Charlie chooses to use the weighted average approach to get more realistic estimates for the activity durations. He meets with the experts and records each activity's most likely duration, optimistic duration, and pessimistic duration. Given the activity's three-point estimations, calculate the weighted average activity duration. Use the formula in Appendix 7.1 and calculate the weighted average (te) for each activity.
