YELLOW BELT 6 SIGMA EXAM
QUESTIONS AND ANSWERS
What is beta testing? - Correct Answers -Beta testing is the act of implementing a new
idea, system, or product with a select group of people or processes in as controlled an
environment as possible.
What is the purpose of beta testing - Correct Answers -The purpose of beta testing is to
reduce the risks and costs inherent in launching an unproven product or system to a
widespread audience.
What is 6 sigma? - Correct Answers -Six Sigma, or 6σ, is both a methodology for
process improvement and a statistical concept that seeks to define the variation
inherent in any process.
What is the premise of 6 sigma? - Correct Answers -The overarching premise of Six
Sigma is that variation in a process leads to opportunities for error; opportunities for
error then lead to risks for product defects. Product defects—whether in a tangible
process or a service—lead to poor customer satisfaction.
What do 6 sigma reduce - Correct Answers -the Six Sigma method ultimately reduces
process costs and increases customer satisfaction.
What is the disadvantage of launching ideas into beta—or to an entire population--
without going through a Six Sigma methodology? - Correct Answers -organizations can
experience unintended consequences from changes, spend money on ideas that don't
end up working out as planned, and impact customer perceptions through trial-and-error
periods rife with opportunities for error.
How does 6 sigma help with decision making? - Correct Answers -organizations can
identify problems, validate assumptions, brainstorm solutions, and plan for
implementation to avoid unintended consequences. By applying tools such as statistical
analysis and process mapping to problems and solutions, teams can visualize and
predict outcomes with a high-level of accuracy, letting leadership make decisions with
less financial risk.
Technically, in a Six Sigma process - Correct Answers -there are only 3.4 defects per
million opportunities.
,6 sigma in percentages - Correct Answers -means 99.99966 percent of the products
from a Six Sigma process are without defect.
At just one sigma level below—5σ, or 99.97 percent accuracy - Correct Answers -
processes experience 233 errors per million opportunities.
How to calculate sigma levels - Correct Answers -# of opportunities - # of defects) # of
opportunities.
X 100 = Yield.
6 sigma aims to reduce - Correct Answers -Time
Defects
Variability
What are the two methodologies of 6 sigma - Correct Answers -DMAIC
DMADV
Which 6 sigma methodology is used in manufacturing or production side of a product or
service, - Correct Answers -DMAIC
What are the DMAIC stages? - Correct Answers -Define - address the identification of
specific processes to be examined
Measure - record data and use metrics to track effectiveness and evaluate efficiencies
Analyze - utilize critical thinking skills to review data and clarify goals
Improve - create changes in business processes geared toward improvement and better
alignment with corporate goals
Control - build a system of checks and adjustments for ongoing improvement in
production processes
What are the DMADV stages? - Correct Answers -Define - address customer needs in
relation to a product or service
Measure - involve the use of electronic data collection to measure customer needs,
response to product, or review of services
Analyze - utilize metrics to evaluate areas where product or service can be better
aligned to customer goals and needs
Design - overlap the improvement of business processes that streamline corporate
goals to best meet client and customer needs
Verify - build a system of tests and models to check that customer specifications are
being met through on-going improvements
Which 6 sigma methodology is most applicable to examining and improving the
customer relations side of a company, - Correct Answers -DMADV
, Which 6 sigma methodology is used in the creation of a new product? - Correct
Answers -DMADV
Which 6 sigma methodology is most commonly used? - Correct Answers -DMAIC
Who created 6 sigma and when - Correct Answers -Six Sigma was developed by Bill
Smith in 1986. Then an engineer at Motorola aimed to help improve the company's
devices which didn't meet the quality standards at the time. He based the approach on
statistical and quality control methods taught by Walter Shewhart, Ronald Fisher, and
Edwards Deming.
What is VOC in 6 sigma? - Correct Answers -Voice of the customer
Which phase is VOC found - Correct Answers -Define phase
Define VOC - Correct Answers -Voice of Customer is the customer's voice,
expectations, preferences, comments, of a product or service in discussion. It is the
statement made by the customer on a particular product or service.
What is Value Stream - Correct Answers -A value stream is all the steps (both value
added and non-value added) in a process that the customer is willing to pay for in order
to bring a product or service through the main flows essential to producing that product
or service.
What is value stream mapping? - Correct Answers -Value stream mapping (VSM) is
defined as a lean tool that employs a flowchart documenting every step in the process.
Many lean practitioners see VSM as a fundamental tool to identify waste, reduce
process cycle times, and implement process improvement.
What does ANOVA stands for - Correct Answers -Analysis of Variance.
What does CAPA stands for - Correct Answers -Corrective Action and Preventive
Action.
What does COPQ stand for? - Correct Answers -Cost of Poor Quality.
What does CTQ stand for? - Correct Answers -Critical-to-Quality.
What does DFSS stand for? - Correct Answers -Design for Six Sigma.
What is the DOWNTIME acronym? - Correct Answers -Defects,
Overproduction,
Waiting,
Non-utilized Talent, Transportation,
Inventory Excess,
