In CPM, the cost slope is determined by
A
$$\frac{{{\text{Crash cost}}}}{{{\text{Normal cost}}}}$$
B
$$\frac{{{\text{Crash cost}} - {\text{Normal cost}}}}{{{\text{Normal time}} - {\text{Crash time}}}}$$
C
$$\frac{{{\text{Normal cost}}}}{{{\text{Crash cost}}}}$$
D
$$\frac{{{\text{Normal cost}} - {\text{Crash cost}}}}{{{\text{Normal time}} - {\text{Crash time}}}}$$
Correct Answer: $$\frac{{{\text{Crash cost}} - {\text{Normal cost}}}}{{{\text{Normal time}} - {\text{Crash time}}}}$$
The term 'cost-slope' is defined as the “increase in the cost of the activity per unit decrease in the time”.Cost slope = $$\frac{{{\text{Crash cost}} - {\text{Normal cost}}}}{{{\text{Normal time}} - {\text{Crash time}}}}$$
