Question 1

What represents the maximum time an activity can be compressed?

Answer 1

Crash Point

Question 2

Which of equation s is used to compute an activity’s cost slope?

Answer 2

(crash cost-normal cost)/(normal time-crash time)

Question 3

What costs are incurred when completing an activity in its realistically shortest time?

Answer 3

Crash Costs

Question 4

What are the assumptions underlying the Cost-Duration Graph?

Answer 4

1. Slope represents a cost per unit per time
2. All accelerations must occur within normal and crash times
3. Crash time represents a limit - the greatest time reduction possible under realistic conditions
4. Normal time assumes low-cost, efficient methods to complete the activity
5. The cost-time relationship is linear

Question 5

What is fast tracking?

Answer 5

Accelerating project completion, typically by rearranging the network schedule and using start-to-start lags

Question 6

What frees up resources that can be assigned to a critical activity.

Answer 6

Outsourcing (subcontracting)
