  1. Which type of control chart is most appropriate for monitoring the number of defects per unit when the sample size varies?

    Answer: u-chart

    The u-chart monitors defects per unit and accommodates variable sample sizes, unlike the c-chart which requires constant sample size.

  2. A process technician applies SMED principles. The primary goal of SMED is to:

    Answer: Reduce equipment changeover or setup time to under ten minutes

    SMED (Single-Minute Exchange of Die) aims to reduce changeover times to single-digit minutes to increase flexibility and reduce batch sizes.

  3. In quality management, an internal audit differs from an external audit primarily because:

    Answer: Internal audits are conducted by the organization's own personnel to assess its own system

    Internal audits are self-assessments conducted by trained staff within the organization to evaluate conformance and identify improvement opportunities.

  4. Which statistical test would a process technician use to determine if a new process setting produces a statistically significant difference in average yield compared to the current setting?

    Answer: Two-sample t-test

    A two-sample t-test compares the means of two independent groups to determine if the observed difference is statistically significant.

  5. The '5 Whys' technique is designed to:

    Answer: Drill down to the root cause by repeatedly asking why a problem occurred

    The 5 Whys iteratively asks 'why' at each level of a problem's symptom to uncover the underlying root cause rather than treating surface symptoms.

  6. Which of the following best describes a 'bottleneck' in process optimization?

    Answer: The step that limits overall throughput because it has the lowest capacity

    A bottleneck is the step with the least capacity, constraining the entire system's throughput; the Theory of Constraints focuses on identifying and elevating bottlenecks.

  7. In the context of ISO 9001:2015, which element is fundamental to demonstrating a quality management system's effectiveness?

    Answer: Risk-based thinking applied to processes and the quality management system

    ISO 9001:2015 requires organizations to apply risk-based thinking to identify, assess, and address risks and opportunities that could affect quality.
