Question

The following is a table of activities associated with

a project at Rafay Ishfaq’s software firm in Chicago, their durations,
and what activities each must precede:
ACTIVITY DURATION (WEEKS) PRECEDES
A (start) 1 B, C
B 1 E
C 4 F
E 2 F
F (end) 2 —
a) Draw an AON diagram of the project, including activity durations.
b) Define the critical path, listing all critical activities in chronological
order.
c) What is the project duration (in weeks)?
d) What is the slack (in weeks) associated with any and all noncritical
paths through the project?

Answer 1

For letter C:

A (1) + C (4) + F (2) = 7 weeks

For letter D:

Slack = Critical Path - (non-critical path)

Slack= 7 - ([1+2+2+2] = 6) = 1

Slack = 1 week

I hope my answer has come to your help. God bless and have a nice day ahead!
