  1. Which statistical tool is most useful for identifying the root cause of recurring equipment failures in a parking facility?

    Answer: Fishbone diagram

    A fishbone (Ishikawa) diagram systematically maps all potential causes of a problem, making it ideal for root cause analysis of recurring failures.

  2. A parking facility tracks the number of customer complaints per month over 12 months. This is an example of monitoring which type of metric?

    Answer: Lagging indicator

    Customer complaints are a lagging indicator because they reflect outcomes that have already occurred rather than predicting future performance.

  3. In the PDCA cycle, what is the primary purpose of the 'Check' phase?

    Answer: Evaluating results against expected outcomes

    The Check phase involves comparing actual results against the planned objectives to determine if the improvement achieved its goals.

  4. Which process improvement methodology focuses specifically on reducing variation and defects to near-zero levels using a five-phase approach?

    Answer: Six Sigma DMAIC

    Six Sigma's DMAIC (Define, Measure, Analyze, Improve, Control) methodology targets defect reduction to 3.4 defects per million opportunities.

  5. A parking manager wants to reduce transaction processing time at pay stations. Which Lean tool would best help identify and eliminate non-value-added steps?

    Answer: Value stream mapping

    Value stream mapping visually displays all steps in a process, allowing teams to identify and eliminate waste or non-value-added activities.

  6. What does a process capability index (Cp) value greater than 1.33 indicate in parking operations quality measurement?

    Answer: The process is capable and meets specifications

    A Cp value above 1.33 indicates the process spread fits comfortably within specification limits, signifying a capable process.

  7. Which approach best describes 'mistake-proofing' (poka-yoke) as applied in parking facility operations?

    Answer: Designing systems that prevent errors from occurring or immediately detect them

    Poka-yoke involves designing processes or equipment so that errors are physically prevented or immediately flagged before they cause defects.
