CPP Process Analysis & Improvement Techniques 3

Question 1

Which lean concept refers to producing only what is needed, when it is needed, and in the amount needed to eliminate overproduction waste?

Accepted Answer

Just-In-Time (JIT)

Answer

Just-In-Time production synchronizes output with demand, preventing excess inventory and overproduction—two forms of lean waste.

Question 2

A team notices that a process output variable correlates strongly with an input variable on a scatter diagram. What is the most appropriate next step?

Accepted Answer

Conduct a designed experiment to confirm causation

Answer

Correlation does not prove causation; a designed experiment (DOE) is needed to confirm whether the input variable truly drives the output.

Question 3

In Total Quality Management (TQM), which principle emphasizes that quality improvement is an ongoing, never-ending effort involving everyone in the organization?

Accepted Answer

Continuous improvement (Kaizen)

Answer

Kaizen, a core TQM principle, promotes continuous incremental improvement by all employees as an ongoing organizational culture.

Question 4

A process that produces 99.99966% defect-free output is operating at approximately which Sigma level?

Accepted Answer

6 Sigma

Answer

Six Sigma quality corresponds to no more than 3.4 defects per million opportunities, equating to approximately 99.99966% defect-free output.

Question 5

Which analysis technique examines the potential failure modes in a process and their effects on the customer to prioritize corrective actions?

Accepted Answer

FMEA (Failure Mode and Effects Analysis)

Answer

FMEA identifies failure modes, assesses their severity, occurrence, and detectability to calculate a Risk Priority Number (RPN) for prioritization.
