After constructing the project network, she now is ready for the following steps.

(a) Find all the paths and path lengths through this project network. Which of these paths is a critical path?

(b) Find the earliest times, latest times, and slack for each activity. Use this information to determine which of the paths is a critical path.

(c) It is now one week later, and Christine is ahead of schedule.

She has already selected a location for the sales meeting, and all the other activities are right on schedule. Will this shorten the length of the project? Why or why not?
