Using the figure below, answer the following:

1. Calculate the ES, EF, LS, and LF times and the slack time for each activity.

2. Identify the critical path for the project.

3. Can the project be completed in 30 weeks?

4. Assume that "Systems Analysis" actually finished at 8 weeks, "Design Input & Output" actually finished at 13 weeks, and "Design Database" actually finished at 18 weeks. Recalculate the expected project completion time.

5. Which activities would you focus on to get the project back on schedule?
