Which of the following best describes 'Special Cause Variation'?
Answer: Variation caused by specific, identifiable factors outside normal operation
Special cause variation arises from specific, unusual factors (equipment failure, material change) and is detected using control charts as points outside control limits.
What is the primary goal of the Improve phase in DMAIC?
Answer: Develop and implement solutions that address root causes
The Improve phase designs, tests, and implements solutions that directly address the root causes identified in the Analyze phase.
A SIPOC diagram helps a team understand a process by mapping:
Answer: Suppliers, Inputs, Process, Outputs, and Customers
SIPOC provides a high-level view of a process by identifying who supplies inputs, what the process steps are, and who receives the outputs.
What does 'Cycle Time' refer to in process improvement?
Answer: The total time to complete one unit or transaction from start to finish
Cycle Time is the total elapsed time to complete one cycle of a process, including both value-added and non-value-added steps.
What is the purpose of a 'Pilot' in the Improve phase?
Answer: To test a proposed solution on a small scale before full implementation
A pilot tests the solution in a limited, controlled environment to validate effectiveness and identify issues before organization-wide rollout.
In Lean Six Sigma, 'Benchmarking' refers to:
Answer: Comparing your process performance against industry best practices or competitors
Benchmarking compares an organization's processes and performance metrics to industry bests or competitors to identify improvement opportunities.
Which metric represents the percentage of time a process produces defect-free output on the first attempt without rework?
Answer: First Pass Yield (FPY)
First Pass Yield measures the proportion of units that complete a process correctly the first time, without rework or repair.
