Suppose you are deciding on whether to crash a project€™s activities and you have the following information:

1. Construct the project€™s network. What is the project€™s duration? What activities have slack time? What is the critical path?

2. Identify the sequencing of the activities to be crashed in the first four steps. Which critical activities should be crashed first? Why?

3. After four iterations involving crashing project activities, what has the critical path shrunk to?

4. Assume that a project penalty clause kicks in after 19 weeks. The penalty charged is $5,000 per week after 19 weeks. How would this information affect your decision to crash the project?
