SPC Control Chart Review Inspection Checklist [FREE PDF]

Statistical Process Control (SPC) chart reviews are mandated under IATF 16949 clause 9.1.1.1 and ISO 9001:2015 clause 9.1 to ensure ongoing process monitoring and measurement system effectiveness. Regular control chart audits detect out-of-control conditions, identify special-cause variation, and verify that corrective actions are properly implemented and documented. This checklist guides QA Engineers through a structured review of X-bar, R-chart, P-chart, and related SPC outputs to confirm proc

Chart Documentation & Setup Verification

Confirm that control charts are correctly established, documented, and accessible to process operators.

  • Are control charts established for all critical-to-quality (CTQ) characteristics identified in the Control Plan?
  • Is the correct chart type (X-bar/R, X-bar/S, P, U, C, IMR) selected based on the data type and subgroup size?
  • Are control limits calculated from a minimum of 25 rational subgroups of process data?
  • Are chart titles, part numbers, characteristic names, and measurement units clearly labeled?
  • Has the measurement system used to collect SPC data been validated through an MSA/Gage R&R study?

Control Limits & Specification Alignment

Verify control limits are correctly calculated and appropriately related to specification limits.

  • Are Upper Control Limit (UCL) and Lower Control Limit (LCL) calculated using the standard 3-sigma methodology?
  • Are control limits kept separate from specification limits on the chart?
  • Have control limits been recalculated following any validated process change or improvement event?
  • Is the process capability index (Cpk) calculated and documented for this characteristic?
  • Does the current Cpk value meet the minimum threshold defined in the customer-specific requirements (CSR)?

Out-of-Control Signal Detection & Review

Evaluate whether operators and engineers are identifying and responding to Nelson/Western Electric rule violations.

  • Are the Nelson Rules or Western Electric Rules applied consistently to detect out-of-control conditions?
  • Are any points plotted beyond the Upper or Lower Control Limits on the current chart?
  • Are there any runs of 7 or more consecutive points on the same side of the centerline?
  • Are there any trends of 6 or more consecutive points consistently increasing or decreasing?
  • Has every identified out-of-control signal been logged and linked to a documented corrective action?
  • Is there a documented Reaction Plan specifying operator response steps for each out-of-control condition?

Data Collection Integrity & Sampling

Confirm data collection practices, sampling frequency, and recording accuracy comply with established procedures.

  • Is data being collected at the sampling frequency specified in the Control Plan?
  • Are subgroups formed from parts produced consecutively (rational subgrouping principle applied)?
  • Are chart entries made in real-time at the point of production, not retrospectively?
  • Are all data points legible, with no erasures or unauthorized corrections on paper-based charts?
  • Are electronic SPC systems secured with audit trail functionality and access controls?

Process Stability & Capability Assessment

Evaluate overall process stability indicators and document findings on process performance indices.

  • Is the process currently in a state of statistical control (no out-of-control signals present)?
  • Is the Ppk (long-term performance index) also calculated and meeting minimum requirements?
  • Is the process distribution approximately normal, or have non-normal distribution methods been applied?
  • Are R-chart (or S-chart) limits stable, indicating consistent within-subgroup variation?
  • Has a written summary of process stability status been generated for management review this period?

Corrective Action Follow-Up & Closure

Verify that previously identified SPC-triggered corrective actions have been closed effectively.

  • Are all open corrective actions from previous SPC reviews tracked in the corrective action system?
  • Have corrective actions been verified for effectiveness through follow-up SPC data analysis?
  • Have lessons learned from SPC findings been documented and shared across similar processes?
  • Have any process improvements resulting from SPC analysis been formally updated in the Control Plan?
  • Are corrective action closure dates within the target timeframes established by the quality system?

Operator Training & Competency Verification

Ensure all personnel responsible for SPC data collection and charting are trained and competent.

  • Are operators responsible for SPC data collection documented as trained on the current SPC procedure?
  • Can operators correctly identify and explain at least three out-of-control run rule violations?
  • Are SPC training records current and reviewed within the past 12 months?
  • Has refresher SPC training been scheduled or completed following any major nonconformance event?

Review Summary & Sign-Off

Capture overall findings, risk assessment, and reviewer authorization for this SPC chart review.

  • Is the overall SPC system for this process rated as effective and in compliance?
  • Have all identified findings been assigned owners with target closure dates?
  • Overall risk level for this process based on SPC findings?
  • Additional observations or notes from this SPC review?
  • Has a photo of the current control chart been captured for this review record?
