Table 1. Activities of Dragonfly project Dependent Activity Ta . n n..s ..A ...nect naco timp pstimates per activity Table 4. Cost estimates per activity \begin{tabular}{|c|c|} \hline Activity & Estimated Cost (E1000) \\ \hline A1 & 15 \\ A2 & 3 \\ A3 & 8 \\ A4 & 140 \\ A5 & 12 \\ A6 & 10 \\ A7 & 22 \\ A8 & 23 \\ A9 & 90 \\ A10 & 22 \\ \hline \end{tabular} Table 5. Scenarios for time improvement 1. How can the project schedule be formally represented, showing interdependence and parallelism among activities? (5pts) 2. What is the critical path of the project? What completion time and budget does it imply (pretending that activity times are deterministic)? (5pts) 3. How does the project schedule and project budget change when activity time uncertainty for activity A3 (5pts)? How for activity A7 (5pts)? How when uncertainty for both activities is introduced (5pts)? 4. How would you approach question 3 if uncertainty was introduced for all the activities simultaneously? Describe the steps you would take, equivalently, your thought process (5pts). [Assume that the interdependence among activities A4 and A9 does not exist]. 5. Should any of the proposed activities seen in Table 5 be shortened to ensure timely completion and, if so, which ones? Consider first the case without uncertainty ( 5pts). Then, provide an answer if uncertainty is introduced for all the activities seen in Table 5. (5pts)
