LEAN SIX SIGMA AND QUALITY
IMPROVEMENT FINAL PAPER EXAM 2026
PRACTICE SOLUTION TESTED QUESTIONS
AND ANSWERS GRADED A+
●● What is Six Sigma? Answer: Six Sigma is a methodology focused on
reducing variation and defects in processes to improve quality.
●● What is Lean Six Sigma? Answer: Lean Six Sigma combines Lean
efficiency principles with Six Sigma quality improvement techniques to
optimize processes.
●● What is DMAIC? Answer: DMAIC is a structured process
improvement framework: Define, Measure, Analyze, Improve, Control.
●● Define (DMAIC stage) Answer: The Define stage identifies the
problem, project goals, and scope of improvement.
●● Measure (DMAIC stage) Answer: The Measure stage collects data to
understand how the current process performs.
●● Analyze (DMAIC stage) Answer: The Analyze stage identifies root
causes of problems and inefficiencies.
, ●● Improve (DMAIC stage) Answer: The Improve stage develops and
implements solutions to improve the process.
●● Control (DMAIC stage) Answer: The Control stage ensures
improvements are sustained through monitoring and standardization.
●● What is process waste in Lean? Answer: Waste refers to activities
that do not add value to a process and should be eliminated.
●● What are the 8 types of Lean waste (DOWNTIME)? Answer:
Defects, Overproduction, Waiting, Non-utilized talent, Transportation,
Inventory, Motion, Extra processing.
●● What is root cause analysis? Answer: A method used to identify the
underlying cause of a problem rather than just treating symptoms.
●● What is the 5 Whys technique? Answer: A root cause analysis
method that repeatedly asks "why" to uncover the fundamental cause of
a problem.
●● What is a bottleneck? Answer: A point in a process where work
slows down or accumulates, limiting overall process efficiency.
