  1. A 5 Whys analysis is best used when:

    Answer: A quick drill-down to a single root cause is needed for a straightforward problem

    5 Whys is most effective for simpler problems with a linear cause-and-effect chain where iterative questioning can reach the root cause quickly.

  2. Which quality metric measures the average number of defects per unit across a production run?

    Answer: Defects Per Unit (DPU)

    Defects Per Unit (DPU) is calculated by dividing the total number of defects found by the total number of units inspected.

  3. In lean quality, 'yokoten' refers to:

    Answer: The horizontal sharing and replication of improvement successes across the organization

    Yokoten is the Japanese practice of spreading successful improvements laterally across similar processes or sites to multiply their benefit.

  4. What distinguishes a 'critical to quality' (CTQ) characteristic from other product features?

    Answer: It directly affects customer satisfaction and has specific measurable requirements

    CTQ characteristics are the specific, measurable attributes of a product or service that are most important to meeting customer requirements and satisfaction.

  5. A Lean leader reviews a process and finds that operators perform the same inspection differently. This is an example of:

    Answer: Lack of standardized work leading to inconsistent quality outcomes

    Inconsistent inspection methods are a symptom of missing or inadequate standardized work, which creates variation and unreliable quality results.

  6. An FMEA (Failure Mode and Effects Analysis) Risk Priority Number (RPN) is calculated as:

    Answer: Severity × Occurrence × Detection

    RPN = Severity × Occurrence × Detection, where each factor is rated on a scale, to prioritize which failure modes require the most urgent corrective action.

  7. In quality improvement, 'PDCA' stands for:

    Answer: Plan, Do, Check, Act

    PDCA (Plan-Do-Check-Act) is the Deming cycle for continuous improvement: plan the change, implement it, check results, and act to standardize or adjust.
