  1. Which Lean concept focuses on producing only what is needed, when it is needed, and in the amount needed?

    Answer: Just-In-Time (JIT)

    Just-In-Time (JIT) is a Lean production strategy that aims to reduce inventory and waste by producing only the required quantity at the right time.

  2. In Six Sigma, what does the term 'sigma level' primarily measure?

    Answer: Process capability relative to defect rate

    Sigma level quantifies how well a process performs by relating its defect rate to the number of standard deviations between the process mean and specification limits.

  3. A value stream map shows a large inventory triangle between two process steps. This icon represents which type of waste?

    Answer: Inventory

    The inventory triangle symbol in value stream mapping specifically denotes accumulated inventory (WIP or finished goods) between process steps.

  4. Which statistical tool is used in Six Sigma to determine whether two or more group means are significantly different?

    Answer: ANOVA (Analysis of Variance)

    ANOVA tests whether the means of multiple groups differ significantly, making it useful for comparing process outputs across different conditions or factors.

  5. What is the primary purpose of a Kaizen event in a Lean Six Sigma initiative?

    Answer: To conduct focused, rapid improvement on a specific process

    A Kaizen event is a concentrated, short-duration (typically 3–5 days) team effort to quickly identify and implement improvements in a targeted process.

  6. A process has a Cp of 1.5 but a Cpk of 0.8. What does this indicate?

    Answer: The process has sufficient spread but is significantly off-center

    Cp measures potential capability (spread vs. tolerance) while Cpk accounts for centering; Cp > Cpk indicates the process has enough room but is shifted away from the target.

  7. Which of the following best describes 'takt time' in Lean manufacturing?

    Answer: The rate at which products must be completed to meet customer demand

    Takt time is calculated as available production time divided by customer demand rate, setting the pace at which each unit must be produced.
