  1. Which statistical tool is used in ergonomics QA to determine whether a process is operating within acceptable control limits over time?

    Answer: Control chart (SPC)

    Statistical Process Control (SPC) uses control charts to monitor process performance and detect variation that signals an out-of-control condition.

  2. In a Plan-Do-Check-Act (PDCA) cycle applied to an ergonomics program, which phase involves analyzing data collected from an ergonomic intervention?

    Answer: Check

    The Check phase of PDCA involves evaluating the results of the intervention against the goals established in the Plan phase.

  3. A process capability index (Cpk) of less than 1.0 in an ergonomics measurement process indicates:

    Answer: The process cannot consistently meet specification limits

    A Cpk below 1.0 means the process produces output outside specification limits, indicating the measurement process is not capable.

  4. Which quality improvement approach focuses on reducing defects to 3.4 per million opportunities and is sometimes applied to ergonomics programs?

    Answer: Six Sigma

    Six Sigma targets 3.4 defects per million opportunities using DMAIC methodology to drive process improvement.

  5. When conducting a root cause analysis for a repetitive strain injury cluster, which tool helps teams visualize cause-and-effect relationships?

    Answer: Fishbone (Ishikawa) diagram

    The Ishikawa (fishbone) diagram organizes potential causes into categories to identify root causes of a problem or injury trend.

  6. In ergonomics quality improvement, a 'leading indicator' differs from a 'lagging indicator' in that it:

    Answer: Predicts future injury risk before incidents happen

    Leading indicators (e.g., ergonomic assessment completion rates) measure proactive activities that predict and prevent future injuries.

  7. A 5-Why analysis conducted on an ergonomics problem is intended to:

    Answer: Drill down to the systemic root cause by repeatedly asking why

    The 5-Why technique iteratively asks 'why' to move past symptoms to the underlying root cause of a problem.
