Reconfigure the Gantt chart in Problem 10.13 to include some different predecessor relationships. Optional: Solve this problem with Microsoft Project.

a. Assume that activities B and C are linked with a “Finish to Finish” relationship. Does that change the expected completion date for the project?

b. For activity F, add a lag of 3 days to its predecessor relationship with activity D. By adding the 3-day lag to F, what is the new expected duration for the project?

c. Suppose you now added a start-to-start relationship between activities F and G to the new Gantt chart. How does this additional relationship change the expected completion date for the project?

Problem 10.13

Develop a Gantt chart for the following activities. Identify all paths through the network. What is the critical path?

Optional: Solve this problem with Microsoft Project. How does clicking on “Tracking Gantt” view demonstrate the critical path?
