Experi

curves
may
be
valid
for
industr
ial
applic

but
have
no role
in
service

as

ures.
False

2.
Experience
curves are the
opposite of
learning curves—
as one rises, the
other falls.
False

3.
Learning
curves are
based on
the
premise that people and organizations become better at their tasks
as the tasks are repeated.
True (Introduction, moderate)
4.
The earliest application of learning curves appears in the work of
architect Frank Lloyd Wright.
False (Introduction, easy)
5.
Learning curves can only be applied to labor.
False (Introduction, moderate)
6.
If the learning rate for a process is 100 percent, then each unit
in a series of units will have the same labor requirements.
True (Introduction, moderate)
7.
If the first unit in a series of units takes 200 days to complete, and
the learning rate is 80%, then the second unit will take 160 days.
True (Introduction, easy) {AACSB: Analytic Skills}
8.
An 80% learning curve means that with each unit increase in
production, labor requirements fall by
20%.
False (Introduction, moderate)
9.
A 90% learning curve implies that each time the production
volume is doubled the direct time per unit is reduced to 90% of its
previous value.
True (Introduction, easy)
10.
The learning rate in the steel industry and the learning rate
in heart surgery have both been estimated at 79 percent.
True (Introduction, and Learning curves in services and
manufacturing, moderate)
11.
A project manager bases his time and labor estimates on a learning
rate of 86%. The actual learning rate turns out to be 89%. The
manager, because of the decreased learning, will complete his
project in more time and with more labor use.
True (Learning curves in manufacturing and services,
moderate)
12.
The learning curve may not be permanent; it can be disrupted by
changes in process, personnel, or product.

Learning curves can be used to establish budgets.
True (Learning curves in services and manufacturing,

14.
The arithmetic approach (or successive doubling approach) to learning curve calculations
allows us to determine the hours required for any unit.
False

15.
The logarithmic approach to learning curve calculations allows us to determine the hours
required for any unit.
True
(Applying

16.
The learning curve coefficient approach may be simpler to use than the logarithmic
approach, but it requires the presence of a table of learning coefficients.
