Thank you

13. Calculate the ES, EF, LS, and LF times and the slack for each activity in the figure below, and identify the critical path for the project. Can the project be completed in 40 weeks? Assume that activity A actually finished at 3 weeks, activity B actually finished at 12 weeks, and activity C actually finished at 13 weeks. Recalculate the expected project completion time. Which activities would you focus on to get the project back on schedule? Activity B Activity E 10 5 7 Activity A Activity D Activity G 1 2 4 15 12 Activity H Activity C 8 5 Activity F 3 8 6 20 14. Calculate the ES, EF. LS, and LF times and the slack for each activity in the figure below, and identify the critical path for the project. Can the project be completed in 30 weeks? Assume that "Systems Analysis" actually finished at 8 weeks, "Design Input & Output" actually finished at 15 weeks, and "Design Database" actually finished at 19 weeks.
