QUESTION: perform the CPM computations to determine (i) early and late start and finish dates for all activities, (ii) free floats and total floats for all activities (iii) critical activities and (iv) critical path.

Draw CPM activity diagram and Summary Table.

FOR BOTH CASES

CASE 1:

Activity	Duration	Predecessor	Lag
A	5	-
B	6	A
C	4	A	3
D	5	A
E	9	B
F	7	B	2
		C
G	6	C
H	8	C
		D	4
I	3	D
J	7	E, G
		F	2
K	4	F, G, H
L	1	H	3
		I
M	2	K, L

CASE 2: (show each and every possiblitiy on CPM activity diagram)

Activity	Duration	Predecessor
A	20	-
B	10	A (SS5, FF6)
C	10	A
D	17	A (SS7, FF3)
E	15	B (SS7, FF0)
F	8	C (FS5)
G	4	C (SS1, FF1)
H	6	D (SS10, FF2)
I	5	E (SS2, FF2), F (FS10)
J	9	G
K	12	G, H
L	12	I, J, K (SS3, FF7)

Thanks in advance.
