Which tool is most commonly used in the Measure phase to visually display the distribution and variation of a process?
Answer: Histogram
A histogram displays the frequency distribution of data, making it the primary tool for visualizing process variation and understanding the shape of a data set during the Measure phase.
What does the acronym CTQ stand for in Lean Six Sigma?
Answer: Critical To Quality
CTQ stands for Critical To Quality, referring to the key measurable characteristics of a product or process whose performance standards must be met to satisfy the customer.
In a Lean Six Sigma project, which type of data is represented by counts or whole numbers, such as the number of defects per batch?
Answer: Discrete data
Discrete data consists of counts or whole numbers that cannot be subdivided meaningfully, such as the number of defects. It is contrasted with continuous data, which can take any value within a range.
Which Lean principle focuses on producing only what is needed, when it is needed, and in the amount needed?
Answer: Just-In-Time
Just-In-Time (JIT) is a Lean principle that aims to eliminate waste by producing the right item at the right time in the right quantity, reducing inventory and overproduction.
What is the primary output of the Control phase in the DMAIC methodology?
Answer: A control plan and standardized procedures
The Control phase produces a control plan and standardized procedures to sustain the improvements made, ensuring the process does not revert to its previous state after the project closes.
A process has a Cp value of 1.5 and a Cpk value of 0.8. What does this indicate?
Answer: The process is capable but is not centered within the specification limits
Cp measures the potential capability (spread relative to spec width) while Cpk accounts for centering. A Cp of 1.5 shows the process has enough spread potential, but a Cpk of 0.8 below 1.0 indicates the process mean is shifted toward or beyond a specification limit.
