Question 1

Which Lean tool is used to visually map the flow of materials and information through a process from supplier to customer?

Accepted Answer

Value Stream Map

Answer

A Value Stream Map (VSM) documents every step in the material and information flow, making waste and non-value-added steps visible so teams can design a leaner future state.

Question 2

In Lean Six Sigma, what does a process capability index (Cpk) value of less than 1.0 indicate?

Accepted Answer

The process is producing defects outside specification limits

Answer

A Cpk below 1.0 means the process spread extends beyond at least one specification limit, indicating the process is incapable and producing defective output.

Question 3

Which type of waste in the Lean framework refers to unnecessary movement of people within a work area?

Accepted Answer

Motion

Answer

Motion waste involves unnecessary physical movement by people—such as walking, bending, or reaching—that adds time and effort without adding value to the product or service.

Question 4

What is the primary output of the Measure phase in the DMAIC methodology?

Accepted Answer

A baseline measure of current process performance

Answer

The Measure phase quantifies the current state of the process by collecting data and establishing a performance baseline, which sets the benchmark against which improvements will be measured.

Question 5

In a Failure Mode and Effects Analysis (FMEA), what does the Risk Priority Number (RPN) represent?

Accepted Answer

The product of Severity, Occurrence, and Detection ratings

Answer

The RPN is calculated by multiplying the Severity (impact of the failure), Occurrence (likelihood of the failure), and Detection (ability to catch the failure before it reaches the customer) ratings, helping teams prioritize which failure modes to address first.
