What is the philosophy that seeks to improve quality by eliminating the causes of
product defects? - Correct Answer - Total Quality Management
Operations management uses tools to help make the right quality decisions. These
tools come from the field of - Correct Answer - statistics.
What is the term for inspecting a random sample of an output from a process and
determining if it produces products within a predetermined range? - Correct Answer -
Common variation
What are descriptive statistics? - Correct Answer - Statistics used to describe quality
characteristics and relationships
Which of the following is an example of common causes of variation? - Correct Answer -

identified and eliminated.
pg. 1
,What happens when a plot of data falls outside preset control limits? - Correct Answer -
The process is out of control.
What does a Cp = 1 tell us? - Correct Answer - It means that the process variability just
meets specifications; the process is minimally capable.
The Six Sigma approach is organized around what plan? - Correct Answer - Define,
Measure, Analyze, Improve, Control
Six Sigma quality implies how many average defects per million? - Correct Answer - 3.4
What is the process of randomly inspecting a certain number of items from a lot or batch

Acceptance sampling
Which of the following is an issue that complicates quality control in service
organizations? - Correct Answer - The presence of the customer during service delivery.
What is a reason that services have lagged behind manufacturing in the use of
statistical process control? - Correct Answer - It is difficult to measure the quality of a
service.
Statistical process control tools are used MOST frequently because - Correct Answer -
they are helpful in measuring and evaluating the quality of products.
Common causes of variation are also known as - Correct Answer - random
What are preset ranges of acceptable quality characteristics? - Correct Answer -
product specifications
What process capability index (Cp) value implies that the process "exceeds minimal
capability?" - Correct Answer - > 1
pg. 2
,What is the way to reduce the parts per million (ppm) defective? - Correct Answer -
increase process capability.
What are the two aspects to implementing the Six Sigma concept? - Correct Answer -
technical tools and people involvement
Burns Industries wants to know information about the diameter of tires they produce. A
sample of 100 tires was taken and the diameters were measured. Based on the sample
the average diameter and the range were calculated. Which category of statistical
process control was used by Burns Industries? - Correct Answer - descriptive statistics
Fang and Bone is implementing Six Sigma to improve the quality of customer service.
Information about current processes was already collected and Fang and Bone is trying
to recognize the main causes of the customer service problem. What step of the DMAIC
plan is the company currently at? - Correct Answer - analyze
What process width is typically used when computing the process capability index Cp? -
Correct Answer - 6o(Imagine the "o" is the"standard deviation of a sample" mark )
Which of the following is TRUE with regard to implementing SPC? - Correct Answer -
How often to inspect depends on product cost and product volume.
Which of the following is TRUE with regard to quality inspection? - Correct Answer -
Processes that do not change frequently do not need to be inspected often.
Which of the following is an issue that complicates quality control in service
organizations? - Correct Answer - The presence of the customer during service delivery.
What is the reason that services have lagged behind manufacturing in the use of
statistical process control? - Correct Answer - It is difficult to measure the quality of a
service.

A company's product design supports its business strategies by - Correct Answer -
designing products that appeal to its customers.
Which of the following is true regarding the relative predictability of the cycle of new
product introductions? - Correct Answer - New car models and new fashion are
predictable, but new skin care products are not.
What are the types of layouts? - Correct Answer - Process, product, hybrid, and fixed
position
Process layout problems can become very complex because - Correct Answer - all
resources relationships are considered.
A company with a pure continuous processing system is MOST likely to use which
layout type? - Correct Answer - Product
Which of the following is characteristic of a product layout as compared to a process
layout? - Correct Answer - Space requirements for inventory storage are lower.
What is a process layout? - Correct Answer - A layout that groups resources based on
similar processes or functions.
What are the two primary tools used to identify closeness measures during the layout
design process? - Correct Answer - REL chart and from-to matrix
What is the name of the shortest distance between two locations using north-south and
east-west movements? - Correct Answer - Rectilinear distance
