Question

1. Calculate total time required to complete each path. Determine the Critical Path(s). Complete the table by indicating the Critical

Path (CP), the amount of slack and whether the task is a milestone.

Task       Predecessors     Duration              CP (Yes/No)?        Slack (Amount)?   Milestone?

PROJECT 2

A2 - 1   

B2 A2    2

C2 A2 2

D2 B2, C2 3

E2 D2 2

F2 D2 3

G2 E2,F2 2

2. Draw a PERT (Network) chart for PROJECT 2.

3. Draw a GANTT chart for PROJECT 2.

4. Schedule PROJECT 2 on a 5-day work week, indicating the tasks and slack available.

Answer 1

Data		Immediate Predecessors (1 per column)
Activity	Time	Pred 1	Pred 2
A2	1
B2	2	A2
C2	2	A2
D2	3	B2	C2
E2	2	D2
F2	3	D2
G2	2	E2	F2

Results
Activity	Early Start	Early Finish	Late Start	Late Finish	Slack
A2	0	1	0	1	0
B2	1	3	1	3	0
C2	1	3	1	3	0
D2	3	6	3	6	0
E2	6	8	7	9	1
F2	6	9	6	9	0
G2	9	11	9	11	0
	Project	11
