  1. In the context of process safety and quality, a Management of Change (MOC) procedure is primarily used to:

    Answer: Ensure changes to equipment, processes, or procedures are safely evaluated before implementation

    MOC ensures that any change to process equipment, chemistry, or procedures is reviewed for safety, quality, and operability impacts before being implemented.

  2. Which sampling method involves dividing a population into subgroups and randomly sampling from each subgroup?

    Answer: Stratified sampling

    Stratified sampling divides the population into homogeneous subgroups (strata) and samples randomly from each, ensuring representation of all groups.

  3. Overall Equipment Effectiveness (OEE) is calculated by multiplying Availability, Performance, and:

    Answer: Quality

    OEE = Availability × Performance × Quality, providing a single metric that captures all major sources of equipment losses.

  4. A process technician implements a corrective action. Which activity confirms the corrective action actually resolved the root cause?

    Answer: Performing effectiveness verification

    Effectiveness verification confirms that the corrective action eliminated the root cause and prevented recurrence of the non-conformance.

  5. Which of the seven basic quality tools is best suited to identify whether a relationship exists between two process variables?

    Answer: Scatter diagram

    A scatter diagram plots two variables against each other to visually reveal whether a correlation (positive, negative, or none) exists between them.

  6. In lean manufacturing, 'takt time' is best defined as:

    Answer: The rate at which customers demand products, calculated as available time divided by customer demand

    Takt time sets the production pace to match customer demand rate, calculated by dividing available production time by units demanded per period.

  7. An acceptance sampling plan with a smaller Acceptable Quality Level (AQL) means:

    Answer: Stricter quality requirements with less tolerance for defects

    A lower AQL sets a stricter maximum acceptable defect rate, requiring higher quality from the supplier to avoid lot rejection.
