The following is a table of activities associated with a project at Bill Figg Enterprises, their durations and what activities each must precede

Problem 3.15 The following is a table of activities associated with a project at Bill Figg Enterprises, 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.
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?
