SCM 4367 EXAM 2 QUESTIONS & SNSWERS
[Lean Toolbox] The two "elements" to improvement described in the Lean Toolbox book
are: - Answer -continuous and breakthrough improvement
[Lean Toolbox] According to the Lean Toolbox book, all of the following are "rules" for
effective use of 5-Why EXCEPT: - Answer -The most influential root cause should be
determined by top management
[Video Lecture] Generally accepted as the threshold for world class quality, is a Cpk
measure of - Answer -Greater than or equal to 2.00
[Memory Jogger II] The USL and LSL are based upon: - Answer -customer
requirements
[Video Lecture] Marketing and engineering have required the weight of a finished box of
cereal to be 15 oz +/- 0.4 oz. The cereal-boxing machine typically fills boxes with a
standard deviation of 0.08 oz. The cereal-boxing machine is currently producing boxes
of cereal that are averaging 15.1 oz. Calculate the current Process Capability: - Answer
-1.250
[Managing Variability Article] The probability that a sample could fall within the control
limits even though the underlying process has changed is called the probability of -
Answer -type II error
[Managing Variability Article] Motorola promoted bringing its process capability up to: -
Answer -Cpk = 2
[Managing Variability Article] W. Edwards Deming distinguishes between - Answer -
common causes and special causes
[Managing Variability Article] The following is a TRUE statement from the Managing
Variability Article: - Answer -There is some amount of natural variability in any process,
and the best we can do is to control this variation.
[Managing Variability Article] Mathematically, regardless of the underlying distribution of
the individual data, when _______________________________________________,
the distribution of the sample mean will approximately follow a normal distribution. (This
is the Central Limit Theorem) - Answer -samples are drawn from it
[Managing Variability Article] Control Charts DO NOT tell us: - Answer -how well our
process is performing relative to customer requirements
[Managing Variability Article] Motorola popularized a simple approach for calculating: -
Answer -the chances that a process meets specifications
, [Managing Variability Article] A value of Cp = 1 corresponds to 3 defects per - Answer -
1000 units produced
[Video Lecture] What is the probability of recording a normally distributed data point that
is ABOVE average? - Answer -50%
[Video Lecture] What proportion of a normal curve is BELOW average? - Answer -50%
NOTE: Control Charts could possibly be used for all of these applications. This quiz
question is asking for the specific application mentioned in the Lean Toolbox book.
[Lean Toolbox] The Lean Toolbox book suggests the following application of Control
Charts: to be able to visualize: - Answer -demand volume
[Lean Toolbox] A principal approach for the reduction variation is: - Answer -Six Sigma
[Video Lecture] Managers must provide all of the following to create a continuous
learning culture that problem-solves EXCEPT: - Answer -Paying employees extra and
providing bonusess for solving problems
[Video Lecture] The mindset that assumes that every person is born with a unique set of
skills and talents is the: - Answer -Fixed Mindset
[Memory Jogger II] In an Interrelationship Diagraph, one can recognize the Key Driver
(or potential root cause) by: - Answer -identifying the potential cause with the most
outgoing arrows
[Lean Six Sigma Memory Jogger] The A3 Report is: - Answer -a one page document
based on the PDCA cycle
[Paul Akers Culture Video] Paul Akers suggests that leaders should "stop fixing
problems." Instead leaders should: - Answer -teach and coach line workers to solve
their own problems
[Paul Akers Culture Video] Paul Akers describes how, at his company, where they have
been meticulously practiced Lean for many years and have become a World-Class
Organization with performance metrics at least 5 times better than other top
organizations, what percentage of lean implementations (experiments) at his company
fail? - Answer -About 50 % - FastCap employees fail very often so they can learn from
what doesn't work
[Video Lecture] For the purposes of our class, the following is the ONLY way to
determine if there is a Special Cause of Variation present (the process is experiencing
an out of control condition) on a Control Chart: - Answer -One or more of the "Control
Chart Rules" are violated
