In a start-to-start relationship, a 2-day lag implies that

successor does not start until two days after the predecessor has started

Project management is generally appropriate:

when the work effort is complex, unique, and uncertain

Which of the following might project managers employ to reduce schedule overruns?

adding time buffers to the schedule

A contingency amount can be :

applied to individual activities or work packages, applied to the project as a whole

To reduce the duration of a project using CPM, it is necessary to make a reduction on the activity with

the smallest cost slope on the critical path

With a Cost Plus Fixed Fee (CPFF)

the customer assumes the risk of cost overruns

one (and only one) bidder is qualified and available to do the work

The EV represents, at a given time:

1
In a start-to-start relationship, a 2-day lag implies that
successor can start two days before the predecessor has started.
the two activities can start on the same date
successor does not start until two days after the predecessor has started
2
Project management is generally appropriate:
when a high-quality product is desired
when the work effort is highly standardized
when the work effort is complex, unique, and uncertain
for most any situation that requires hard work
3
Activity has two immediate predecessors with early finish times are 15 and 19, then the early start time of activity is
cannot be determined from this information
19
15
4
Which of the following might project managers employ to reduce schedule overruns?
(a) multi-tasking
adding time buffers to the schedule
procrastination by workers
5
A contingency amount can be :
applied to individual activities or work packages
continually increased to cover cost escalation
applied to the project as a whole
6
To reduce the duration of a project using CPM, it is necessary to make a reduction on the activity with
the largest cost slope not on the critical path
the smallest cost slope on the critical path
the smallest cost slope not on the critical path
the largest cost slope on the critical path
7
Which of the following contracts is most risky to the customer?
quaranteed maximum price
cost plus fixed fee
firm fixed price
time and materials
8
Which method provides the least accuracy when estimating total project cost:
analogy
cost engineering
expert opinion
parametric
9
Five days after starting a work task, the supervisor assesses that the task is 25% completed. What is the time remaining
15 days
10 days
cannot be estimated
20 days
10
If the risk likelihood is 0.4, the risk impact is 6.0, the risk consequence is
6.6
4
None of these
2.4
11
Project Engineering is about being able to
making money for the company
tell people what to do
communicate effectively
do math
12
In a network, the critical path is that sequence of activities that requires
both a and b
the longest time to complete
the shortest time to complete
13
Project completion has a Te = 15 weeks and Vp = 9, what is the probability that the project will finish less than 18,
-1
0.333
none of these
1
14
With a Cost Plus Fixed Fee (CPFF)
the customer assumes the risk of cost overruns
cutting-corners to reduce costs is a potential risk
contractor risks underestimating the cost and losingmoney on the project
the price to the customer remains the same
15
Sole-sourcing means:
searching for answers
one (and only one) bidder is qualified and available to do the work
among several qualified sources, just one will be invited to bid
multiple qualified bidders will be invited to bid
16
The EV represents, at a given time:
actual expenditures according to time cards and invoices
the amount budgeted for project work as of that time
how much it will cost, according to the budget, to complete the project
how much work actually been done and the amount originally budgeted for it
17
If a = 3, m = 5, and b = 6, then:
te = 4.667 and V = 1.5
neither
te = 4.833 and V = 0.5
18
The functions of management generally include:
leadership, supervision, analysis, and design
planning, assembly, installation, and testing
planning, organizing, control, and leadership
(a) none of the these.
19
Resource leveling
All of these answers
can potentially turn non-critical activities intocritical ones
makes the workload on resources more evenly distributed
makes use of float (slack) to move activities to to timeslots
20
The forward and backward pass:
determine the float (slack) of activities
determine the critical path.
determine the early and late start dates of activities,respectively
All of these answers
21
Often, the impact of changing system requirements late in the project is that it
increases project costs
greatly improves project performance
improves worker morale and relations between client andcontractor
shortens the scheduled completed date
22
A project was estimated to cost $100,000, and as of a given date the EV is $80,000 and the CPI is 0.8. What is forecast?
$25,000
None of these
$24,000
$20,000
23
The advantages of scheduling include all of the following EXCEPT:
is necessary in order to determine the workload on individuals
is necessary in order to utilize resources efficiently.
is necessary in order to determine the cash flow
provides absolute certainty about the end date
24
To find the shortest possible project duration for the least cost
crash all activities in the project, then relax those not on the CP
crash all activities not on the CP, then relax all critical activities
crash all activities in the project, then relax those on the critical
(a) crash all activities on the critical path (CP), then relax all non-CP
25
User requirements :
are usually obvious and do not require much attention
emphasize what is needed
are defined by the contractor or developer
emphasize how the work should be done
