Gauge R and R Study Verification

Inspection template for verifying Gauge R and R study setup, execution, results, and acceptance criteria.

Study Identification and Scope

• Study ID, date, and site are documented
• Measurement characteristic and specification are clearly defined
• Study objective is stated as variable or attribute Gauge R&R verification
• Applicable standard or customer requirement is identified
  Examples: AIAG MSA, IATF 16949, customer-specific MSA requirement.
• Study plan or approved protocol is available at the inspection point
• Gauge, fixture, software, and revision status are identified
• Reference document or SOP is linked

Study Setup and Sample Selection

• Parts used represent the expected process variation
• Number of parts meets the approved study plan
• Number of operators meets the approved study plan
• Trials per operator meet the approved study plan
• Parts were randomized and presented in a different order for each trial
• Operators were blinded to previous results or part identity where required
• Environmental conditions were controlled or recorded
  Record temperature, humidity, vibration, lighting, or other conditions affecting measurement.

Measurement System and Execution

• Measurement device calibration is current
• Calibration due date is within the valid period
• Measurement method was followed consistently for all trials
• Fixture, software, and setup were unchanged during the study
• Operator training or qualification for the measurement method is documented
• Data sheets or electronic records show no missing readings
• Any deviations, interruptions, or re-runs are documented

Results and Acceptance Criteria

• Repeatability and reproducibility results are calculated
• Percent study variation or percent contribution is reported
• Number of distinct categories is reported when applicable
• Acceptance criteria are documented before review
• Gauge R&R result meets acceptance criteria
• Study conclusion is supported by the data and analysis

Review, Approval, and Corrective Actions

• Non-conformances or deficiencies are documented
• Corrective actions are assigned for failed or marginal items
• Retest or re-study is required
• Inspector signature
• Review date and time
