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
