A.A statistical concept for understanding process variation
B.A financial accounting standard
C.A human resources staffing model
D.A product design patent system
Explanation: The CSSC Yellow Belt manual defines Six Sigma as both a methodology for process improvement and a statistical concept that addresses variation in a process. Variation creates opportunities for error, which can become defects and harm customer satisfaction.
8What is the primary advantage of data-driven decision making in Six Sigma?
A.It eliminates the need for experienced leaders
B.It validates assumptions with measurement and analysis before changes are widely implemented
C.It guarantees every solution will work on the first try
D.It replaces customer feedback with internal opinions

A.Making improvements only to increase internal activity
B.Focusing improvement on customer needs and measurable process performance
C.Avoiding process data when experienced managers disagree
D.Treating every process exactly the same regardless of customer impact
Explanation: The CSSC manual introduces customer-focused improvement as a core Six Sigma principle. Teams combine customer needs with measurements and process improvement methods to increase satisfaction and business performance.
10At its most basic statistical definition, a Six Sigma process has about how many defects per million opportunities?
A.3.4
B.233
C.6,200
D.66,800
Explanation: The CSSC manual states that a Six Sigma process has only 3.4 defects per million opportunities. This very low defect rate is why even small sigma-level differences can create large differences in customer impact and cost.
