Activity	Immediate predecessor
a) Calculate durations along all project paths
b) Calculate Te
c) Define immediate predecessors	h
d) Develop WBS
e) Draw a network diagram
f) Estimate task durations
g) Find the critical paths
h) Generate a complete, detailed task list
i) Identify project objectives
j) Write project scope statement

2. Draw network diagram for the following list of activities and their immediate predecessors. Draw start and end nodes.

5. What is/are the critical path(s) amongst the following paths through a project?

Path 1: A-B-D = 8.5 mos.

Path 2: B-C-I-J = 10 mos.

Path 3: A-B-E = 5.5 mos.

Path 4: B-F-G-J = 12 mos.

6. What is the shortest possible completion time for a project, given the following paths through a project from start to finish?

A-B-D-F = 14 weeks

A-G = 22 weeks

A-C-H-I-J = 19 weeks

7. Identify all non-critical activities in the project with the following paths:

A-B-C = 22 weeks

B-J-K = 18 weeks

A-B-D-E = 22 weeks

A-B-I = 14 weeks

B-L = 20 weeks

8. Identify all non-critical activities for a project with the following paths

A-B-C = 10 days

A-B-D = 8 days

A-B-E-F = 8 days

A-B-G = 9 days
