solution

Given the information in Table 1, construct a network diagram of the project under normal conditions.

Then answer the questions in the Table 2 (next page).

Next, assume that the project manager will receive a bonus of $600 per day for each day that the project duration is reduced. However, the project manager is also responsible for the expediting costs associated with crashing the project. Based on this information, indicate which tasks should be expedited & in which order. Record your answers in Table 3 (next page).

Activity	Predecessor	Normal Duration	Days Available to Crash	Crash Cost (per day)
A	None	6	2	$ 625
B	A	3	3	$ 125
C	A	2	2	$ 300
D	A	9	4	$ 60
E	B & C	5	1	$ 300
F	D & E	8	2	$ 700
