b) statistical variances
c) costs
d) contingency plans

Ans: c
Response: Refer to section 9.1, critical path method crashing a project.
Level: intermediate

2. If deterministic time estimates are used and if project ________ are firm, there is a high
likelihood that it will be necessary to crash the last few activities of most projects.
a) Deliverables
b) Cost objectives
d) Budgets

Ans: c
Response: Refer to section 9.1, critical path method crashing a project.
Level: easy

3. This schedule compression technique expedites a project.
a) Crashing
c) Fast-tracking
d) Blitzing

Ans: c
Response: Refer to section 9.1, fast-tracking.
Level: easy

4. The ________ approach to constrained resource scheduling problems is the only feasible
method of attacking the large, nonlinear, complex problems that tend to occur in the real world of
project management.
a) Goal programming
b) Heuristic
c) Optimization modeling
d) Linear programming

Ans: b
Response: Refer to section 9.5, heuristic methods.
Level: easy

5. The ________ heuristic provides a general solution for critical path and time. It is usually the
default rule for a schedule.
a) as soon as possible
b) as late as possible
c) Minimum slack first

Ans: a
Response: Refer to section 9.5, heuristic methods.
Level: easy

6. The standard practice with PERT/CPM is to estimate activity times under the assumption of

Ans: normal.
Response: Refer to section 9.1, critical path method crashing a project.
Level: easy

7. When using heuristic solutions to schedule, ___________ will always take precedence.

Ans: technological necessities.
Response: Refer to section 9.5, heuristic methods.
Level: easy

8. The usual purpose of the ________ scheduling heuristic is to delay cash outflows as long as
possible.

Ans: as late as possible
Response: Refer to section 9.5, heuristic methods.
Level: intermediate
9. A project task is said to be system constrained if it requires a fixed amount of ________ and
known quantities of resources.

Ans: time
Response: Refer to section 9.2, the resource allocation problem.
Level: intermediate

10. Resource leveling aims to minimize the period-by-period variations in resource loading by

Ans: slack allowances
Response: Refer to section 9.4, resource leveling.
Level: intermediate

True/False

11. The formula for computing the cost/time slope for each activity that can be crashed is (Crash
cost - normal cost) / (crash time - normal time).

Ans: True
Response: Refer to section 9.1, critical path method crashing a project.
Level: intermediate

12. Most heuristic solution methods start with the master schedule and analyze resource usage
period by period, resource by resource.

Ans: False
Response: Refer to section 9.5, heuristic methods.
Level: intermediate

13. One of the most common priority rules is the longest task first.

Ans: False
Response: Refer to section 9.5, heuristic methods.
Level: intermediate

14. A project is said to be overdetermined if all three variables --- time, cost, and specifications --
- have been fixed by the project sponsor.
Ans: False
Response: Refer to section 9.2, the resource allocation problem. In any three-variable equation,
only two of the quantities can be fixed.
Level: easy

15. Resource leveling describes the amounts of individual resources an existing schedule requires
during specific time periods.

Ans: False
Level: easy

16. While standard practice and rules of thumb are sufficient for estimating the resource
needs for normal progress, careful planning is critical when attempting to expedite
a project.

Ans: True
Response: Refer to section 9.1
Level: easy

17. When crashing a project, a change in technology with which something is done will change.
In economics terms, this is a change in the “production function.”

Ans: True
Response: Refer to section 9.1
Level: intermediate

shifting tasks within their slack allowances.

Ans: False
Response: Refer to section 9.3 (resource leveling aims…..)
Level: easy
