LEAN SIX SIGMA SERIES 2026
COMPREHENSIVE EXAM SCRIPT FULL
QUESTIONS AND CORRECT ANSWERS
◉Six Sigma and the Customer. Answer: Only the customer can
establish the requirements, what is considered a defect, and decide
whether product or service is acceptable or not
◉The Six Sigma Objective. Answer: Reduce variation and center the
process on the peak of the Gaussian curve
◉Process Improvements. Answer: Inputs: measure inputs and
outputs and identify variation
Process: implement solutions to reduce variation in process
Output: control revised process
◉What is sigma level?. Answer: The sigma level defines its capability
to operate within specifications without defects (i.e. the number of
standard deviations that fit between the mean and upper and lower
specifications)
, ◉Six Sigma Long Term Process Availability. Answer: A six sigma
process operates within specifications in 99.9997% of the instances
near perfection
◉Two Methodologies of Six Sigma. Answer: DMAIC (Define,
Measure, Analyze, Improve, Control)
DFSS (Design For Six Sigma)
◉DMAIC. Answer: 1.Define (customer's needs and improvement
obj.)
2.Measure (determine process performance and capability to
customer needs)
3. Analyze (identify key process performance drivers in data)
4. Improve (statistically validate improvement opportunities)
5. Control (set appropriate controls to ensure improvements'
sustainability)
◉DEFINE Phase Toolkit. Answer: Project Charter, Stakeholder
Analysis, SIPOC, Rolled Throughput Yield, VOC, Affinity Diagram,
Kano Model, CTQ, Benchmarking
◉Rolled Throughput Yield. Answer: The product of the yields of
each of the steps in the process
