• Scheduling Projects
CHAPTER

3. project
A unique collection of
activities creating a
particular outcome.

4. project
A unique collection of
activities creating a
particular outcome.

5. A unique collection of
activities…

6. WBS
Work Breakdown
Structure, a document
specifying the tasks
required to finish a project.
A unique collection of
activities…

7. immediate
predecessor
A task that must be
completed before
another task can start.

8. Values:
How will the
organization
conduct itself in
its mission?
Example Project
Data
Task Duration Immediate
(days) Pred.
None
None
Start
Finish
Finish

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.

12. CPM
Critical Path Method,
a project management
methodology developed
by DuPont Corporation.

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?

23. Sample View of Spreadsheet Model

24. slack
The degree to which a
task may be delayed from
its early start without
delaying the project.

25. slack
The degree to which a
task may be delayed from
its early start without
delaying the project.
LS - ES = slack
or
LF- EF = slack

26. critical path
The longest path through
a project network;
determines the length of
the entire project.

27. critical path
The longest path through
a project network;
determines the length of
the entire project.
Tasks with Zero Slack

28. Gantt chart
A scheduling diagram
that illustrates activities
across a horizontal time
line.

29. Gantt Chart with Early Start/Early Finish Timings

30. Gantt Charts Displayed by Project Management Software

31. crashing
Expediting the
completion of a task or
group of tasks, to finish a
project sooner.

32. PERT
Program Evaluation and
Review Technique, a
project management
methodology developed
by the US Navy.

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.
