4. Six Sigma Quality Control
a. Six Sigma quality control consists of a disciplined, statistics-based system aimed at producing
not more than 3.4 defects per million iterations for any business process—from manufacturing to
customer transactions.
b. The Six Sigma process of define, measure, analyze, improve, and control (DMAIC) is an
improvement system for existing processes falling below specification and needing incremental
improvement.TheSixSigmaprocessofdefine,measure,analyze,design,andverify(DMADV)is
an improvement system used to develop new processes or products at Six Sigma quality levels.
c. Both Six Sigma processes are executed by personnel who have earned Six Sigma “green belts” and
Six Sigma “black belts” and are overseen by personnel who have completed Six Sigma “master
black belt” training.
d. The statistical thinking underlying Six Sigma is based on the following three principles: all work is
a process, all processes have variability, and all processes create data that explains variability.
CORE CONCEPT
Six Sigma programs utilize advanced statistical methods to improve quality by reducing
defects and variability in the performance of business processes.

Discussion Question: What did CAMC do to sustain the quality gains and process
standardization benefits derived through its implementation of Six Sigma?
Answer: To sustain these benefits, CAMC has instilled a continuous improvement mindset into the
ACTIVITY
Consider adding a File Attachment assignment requiring the student to fully explore and explain
how the CAMC has used Six Sigma to improve operational effectiveness and develop sustainable
competitive advantage.
Ask the student to describe specific areas of operation where Six Sigma has been implemented and
how that has impacted operations. Ask the student to explain how CAMC has been able to lock in the
gains made through this program. You can send the student to the following links to supplement the
information in the Illustration Capsule:
