  1. A bank processes 200 loan applications per week, and each application spends an average of 2 weeks in the system. How many applications are in process on average?

    Answer: 400

    By Little's Law, Inventory = 200 × 2 = 400 applications.

  2. A step has 3 parallel workers, each taking 12 minutes per unit. What is that step's capacity per hour?

    Answer: 15 units

    Each worker makes 5 units per hour, so 3 workers produce 15 units per hour.

  3. What does 'takt time' represent in a production process?

    Answer: The pace of production needed to match customer demand

    Takt time equals available production time divided by customer demand.

  4. A plant runs 480 minutes per day and customer demand is 160 units per day. What is the takt time?

    Answer: 3 minutes per unit

    Takt time = 480 / 160 = 3 minutes per unit.

  5. On a control chart, a single point falling outside the upper control limit most likely signals what?

    Answer: Special-cause variation

    Points beyond control limits indicate an assignable, special cause that should be investigated.

  6. Which DMAIC phase focuses on confirming root causes through data analysis?

    Answer: Analyze

    The Analyze phase uses data to identify and verify the root causes of defects.

  7. A pull system such as kanban primarily aims to do which of the following?

    Answer: Produce only in response to actual downstream demand

    Kanban triggers production only when downstream consumption signals a need, limiting inventory.
