Question

In the following table the activities with their precedence sequence and expected time​ (days) are listed for a project on which Carl​ Betterton's construction company is​ working:

                                                                                      

Activity	Immediate​ Predecessor(s)	Time​ (days)
A	minus−	5
B	A	4
C	A	6
D	B	6
E	B	4
F	C	4
G	D	6
H	​E, F	7

​Carl's team should be able to complete the project in

nothing

days.

Critical path activities for​ Carl's project are

.

Answer 1

The various paths and their expected completion time of the project are

• A-B-D-G = 5+4+6+6 = 21 days
• A-B-E-H = 5+4+4+7= 20 days
• A-C-F-H = 5+6+4+7 = 22 days

So the critical path is A-C-F-H as it has the longest expected completion time of 22 days

Expected completion time of the project = expected completion time of the critical path = 22 days. So Carl's team should be able to complete the project in 22 days
