Consider a project with 6 activities and three time-estimates. X2 X3 X4 Time (Weeks) Cost Immediate Activity Predecessor Normal Crash Normal Crash A 5 X1 $20,000 $40,000 B A 6 $10,000 $15,000 A 5 $6,000 $20,000 D B 6 $8,000 $12,000 E 7 $10,000 $14,000 F E, D 8 X6 $8,000 $9,000 Question 1: Use MS Excel to examine this project. Randomly choose x, through X6 the difference between the normal time and crash time cannot exceed 2 weeks. For example, if the normal time is 7, then you may choose 6 or 5, but not 4. What is the critical path? Question 2: If you must shorten the project by 2 weeks, which task(s) would you shorten? What would the final total project cost be? X5
