1. Fast-tracking can be an option to get your project back on schedule.
1) Please explain what fast tracking is by giving me a tiny example from your field project (I think you have already been familiar with this style: Define the term and then give me an example.).
2) Explain why fast tracking is of high risk (Usually).

(a) Draw the AOA diagram.
(b) Find the critical path.
(c) Find the completion time.
The nomenclature AB means the activity between nodes A and B.

Using the critical path, find:
(a) The probability of completing this project in 12 weeks (or less), as the client desires.
(b) The probability of completing this project in 13 weeks (or less).
(c) The probability of completing this project in 16 weeks (or less), the client's drop-dead date.

Find:
1. The network
2. All expected activity times, stances, and slacks.
3. The critical path and expected completion time.
4. The probability the project will be done in 23 days.
5. The completion time corresponding to 95% probability.
