I need help Software Project Management question

Q1. For the following table of information:

       a) Draw a network diagram (Activity on Arrow)

       b) List down all the network paths

       c) Determine the critical path(s)

Activity	Predecessor	Duration
A	Start	5 days
B	A	2 days
C	A	3 days
D	B	4 days
E	C	6 days
F	C	3 days
G	D, E	4 days
H	F	2 days
I	G	3 days
J	H	1 day
K	I, J	2 days

Answer 1

Without earlier/later start and finish

a) Network diagram 4,5 B, 2 I, 3 t, E, 6 20"0 2 x 4, 2 J L o Duration 6) All network paths A - B -> D - G - I - K A - (-) &-) 4-) I -) k д-)(-) (-) и - J-k 2o 23 16 I eritical path A-) (-) E-) 6-) I - K

With earlier/later start and finish

وع Earlier stast latest Start hini latest, finish 6 a) Network diagram 11 14 2 7 5 0,7 A 5 B, 2 1628 11628 1 O 13/18 I, 3 O E,6 6 138 3. 9 4 14 2 x 6 4, 2 Jy h! 18/13 18 1131 14 4 106/20 118/23 118/23 Duration 2o 6) All network paths A - B -> -) h-) I - K A - (-) &-) 6-) I - k A) (-) F-) 1- J -)k 23 16 i esitical path A) (-) {-) G-) I -> K

• network diagram is as shown
• All the paths are shown with their respective duration
• critical path is the path with maximum duration that is 23 in this case
