  Verify Limits: Review the lower and upper limits set for the inspection characteristic. Make sure they are appropriate for the product or process being inspected.
  Adjust Values: If the average is indeed outside the limits due to valid measurement data, consider whether the limits need to be adjusted based on updated quality standards or specifications.
  Recalculate Average: If there were any data entry errors, correct them and recalculate the average to see if it now falls within the acceptable range.
  Consult Quality Management Team: If you are unsure about the limits or the measurement data, consult with your quality management team or relevant stakeholders to ensure compliance with quality standards.
