  1. In a Measurement System Analysis (MSA), what does %GRR represent?

    Answer: The proportion of total observed variation attributed to the measurement system

    %GRR expresses how much of the total study variation is due to the measurement system (gage); values below 10% are generally acceptable.

  2. Which of the following is an example of an attribute measurement?

    Answer: Classifying a weld as pass or fail by visual inspection

    Attribute measurement classifies items into categories (pass/fail, go/no-go) rather than recording a continuous numerical value.

  3. The 5S methodology in a production environment refers to Sort, Set in Order, Shine, Standardize, and:

    Answer: Sustain

    Sustain (Shitsuke) is the fifth S, focusing on maintaining discipline and making the other four S's a habit in the workplace.

  4. An operator measures 10 samples and calculates the standard deviation to be 0.05 mm. If the specification tolerance is 0.50 mm, what does this suggest about process capability?

    Answer: The process likely has good capability since the spread is much smaller than the tolerance

    A standard deviation of 0.05 mm against a 0.50 mm tolerance (ratio of 1:10) strongly suggests the process has good spread capability relative to the specification.

  5. Which corrective action tool requires teams to document the problem, root cause, containment, corrective action, and verification in a structured report?

    Answer: 8D Report

    The 8D (Eight Disciplines) report is a structured problem-solving methodology requiring documentation of containment, root cause analysis, corrective actions, and verification.

  6. In FMEA, Risk Priority Number (RPN) is calculated by multiplying Severity, Occurrence, and:

    Answer: Detection

    RPN = Severity × Occurrence × Detection, where Detection measures how likely the failure mode will be caught before reaching the customer.

  7. A production line running at 95% first-pass yield means:

    Answer: 95% of units pass inspection without requiring rework or repair

    First-pass yield (FPY) is the percentage of units that complete the process correctly the first time without needing rework, repair, or scrap.
