Question
Consider the following work breakdown structure:
Task Immediate Predecessor Duration
A - - - 5
B A 12
C A 7
D C 6
E B, D 8
F D 3
G D 3
H E 4
I F, G, H 6
Which of the following are so-called "critical path" tasks in this situation?
Explanation / Answer
The predecessor diagram as follows :
A
B
C
D
E
F
G
H
I
The possible parallel paths and their corresponding durations as follows :
A-B-E-H-I = 5 + 12 + 8 + 4 + 6 = 35
A-C-D-E-H-I = 5 + 7 +6 + 8 + 4 + 6 = 36
A-C-D-F- I = 5 + 7 + 6 + 3 + 6 = 27
A-C-D-G-I = 5+ 7+ 6+ 3 + 6 = 27
Out of abpve, path A-C-D-E-H-I has the longest duration and hence forms the Critical Path
THE CRITICAL PATH TASKS IN THIS SITUATION ARE : A-C-D-E-H-I
A
B
C
D
E
F
G
H
I
