9. AOA
A style of project network
diagram in which arrows
represent tasks and their
connections with nodes
represent precedence
relationships.
Start Finish
10. AON
A style of project network
diagram in which nodes
represent tasks and the
connecting pathways
represent precedence
relationships.
Start Finish
11. path
Any sequence of linked
activities that connect
the beginning with the
end of a project network.
13. Task Timing: Early Start (ES) and
Early Finish (EF)
Example Project
Data
Task Duration
(days)
START
Start = 0
FINISH
Finish = 7
14. Task Timing: Early Start (ES) and
Early Finish (EF)
Example Project
Data
Task Duration
(days)
START
Start = 0
FINISH
Finish = 7
ES: What is the earliest
you could start working
on this task?
15. Example Project
Data
Task Duration
(days)
START
Start = 0
FINISH
Finish = 7
ES: What is the earliest
you could start working
on this task? EF: What is the earliest
you could be finished?
Task Timing: Early Start (ES) and
Early Finish (EF)
16. Determining Early Start (ES) and
Early Finish (EF) TIMES
ES: What is the earliest
you could start working
on this task?
17. Determining Early Start (ES) and
Early Finish (EF) TIMES
ES: What is the earliest
you could start working
on this task?
Early Start Time Rule:
Early Start time of a task = largest of the
Early Finish times of its immediate
predecessors.
18. Determining Early Start (ES) and
Early Finish (EF) TIMES
ES: What is the earliest
you could start working
on this task?
Early Start Time Rule:
Early Start time of a task = largest of the
Early Finish times of its immediate
predecessors.
EF: What is the earliest
you could be finished?
EF = ES + task time
19. Task Timing: Late Start (LS) and
Late Finish (LF)
Example Project
Data
Task Duration
(days)
START
Start = 0
FINISH
Finish = 7
LS: What is the latest
you can delay starting
on this task?
20. Task Timing: Late Start (LS) and
Late Finish (LF)
Example Project
Data
Task Duration
(days)
START
Start = 0
FINISH
Finish = 7
LS: What is the latest
you can delay starting
on this task?
LF: What is the latest
you can delay finishing
this task?
21. Determining Late Start (LS) and Late
Finish (LF) TIMES
LS = LF - task time
LS: What is the latest
you can delay starting
on this task?
22. Determining Late Start (LS) and Late
Finish (LF) TIMES
LS = LF - task time
LS: What is the latest
you can delay starting
on this task?
Late Finish Time Rule: Late Finish
(LF) time of a task = smallest of the
Late Start (LS) times of its immediate
followers.
LF: What is the latest
you can delay finishing
this task?
33. probabilistic
Variable or not well
known in advance;
subject to randomness.
This represents
uncertainty in planning.
34. Central Limit
Theorem
The observation that
sample values approximate
a normal distribution,
regardless of the
underlying distribution of
the population being
sampled.
35. project life cycle
A conceptual model of a
project’s progress through
distinct categories of
activity, namely defining,
planning, executing, and
closing the project.
1st Ed chapter quote: My personal philosophy is not to undertake a project unless it is manifestly important and nearly impossible.
