PPAP Submission Assessment: Planning a Robust Approval Package

01How to use this chapter

This chapter separates the uploaded assessment criteria from practical KEVOS implementation guidance. The section titled Source-derived assessment criteria preserves the intent, terminology and checklist detail supplied in the uploaded PPAP Assessment. The surrounding handbook guidance explains how a manufacturing or supplier-quality team can organise evidence, perform a readiness review and spot gaps before formal submission. Where the uploaded source states a numeric threshold, edition reference or customer-specific expectation, it is identified as source-derived rather than presented as a universal rule.

Use the chapter in three passes. First, read the purpose and workflow to understand what the element is meant to prove. Second, work through the source-derived prompts against the actual part number, engineering revision and production process. Third, close the red flags and collect objective evidence before the package is released. For large PPAPs, record the evidence location beside each source prompt so another reviewer can repeat the assessment without relying on verbal explanation.

02Handbook workflow

1. Confirm the APQP trailCollect evidence that product and process planning occurred before the submission was assembled. The assessor should be able to see who participated, what was reviewed and how open actions were closed.
2. Agree submission expectationsRecord the submission level and any element-specific agreements before the due date. For Level 2 or Level 4, explicitly identify which elements are being submitted.
3. Freeze the document baselineVerify part numbers, revision levels, drawing/specification status, dates and approvals across the package. Do not mix current evidence with obsolete records.
4. Check completeness by product and processMake sure subcomponents, alternate or backup processes and external processes that affect the submitted part are not missing from the evidence chain.
5. Review the reason for submissionThe reason should be detailed enough for the approver to understand whether the package is for new product, change, correction, resubmission or another agreed trigger.
6. Perform a pre-submission auditUse the source prompts as a gate review before sending the package. Resolve legibility, missing signatures, conflicting units, unexplained exceptions and timing issues.
7. Control the resubmission storyWhen the package returns, retain a clear record of the previous deficiency, the action taken and the updated result so the approver can see what changed.

03Evidence package to retain

The assessment is stronger when each conclusion points to a controlled record rather than a statement that the requirement is “covered”. The following evidence set is a practical minimum for this chapter; actual customer and contractual requirements govern the live submission.

• APQP activity records and meeting evidence
• Supplier and Organization team participation records
• Controlled document register with revision/date status
• Agreed PPAP submission level and element list
• Reason-for-submission statement
• Resubmission gap/corrective-action record where applicable
• Evidence that subcomponents and subprocesses are included
• Submission timing record and approval communication

04Source-derived assessment criteria

• 1.Is there evidence of APQP execution?
• 2.Is there evidence of supplier team engagement?
• 3.Is there evidence of Organization team engagement?
• 4.Are all documents controlled?
• 5.Is the submission to PPAP 4th edition requirements?
• 6.Is there clear and proper detail provided on “Reason for Submission”?
• 7.Was proper submission level agreed upon prior to submission?
• 8.If Level 2 or 4 submissions shall clearly document elements being submitted.
• 9.Is there evidence of prior agreement for submission requirements?
• 10.In case of re-submissions, is it identified the reason for resubmission, previous gaps, corrective action taken and updated results provided?
• 11.Are all documents legible and understandable?
• 12.Are all submission subcomponents/processes included?
• 13.Does the PPAP exhibit proper detail and compliance?
• 14.Was the PPAP submitted on time?

05Common red flags

These are practical review signals derived from the relationships and controls repeatedly required by the source. A red flag does not automatically mean the submission must be rejected; it means the condition deserves documented resolution before approval.

• Submission level chosen after the package is already complete
• Different revision levels appear in drawing, PFMEA, control plan and dimensional data
• A resubmission contains new results but does not explain the previous rejection
• Key documents are screenshots or uncontrolled copies with unclear status
• The package omits an outsourced or backup process that can affect product conformity
• The reason for submission is generic and does not explain what changed
• Evidence is present but cannot be traced to the submitted part or revision

06Cross-document interfaces

PPAP elements should not be reviewed as isolated files. Check the following interfaces for consistent part identity, revision, characteristic naming, operation numbering and control logic.

07Assessor close-out checklist

• The element is present or a controlled waiver/agreement explains why it is not required.
• The submitted record identifies the correct part number and engineering revision where applicable.
• The evidence is legible, understandable, controlled and traceable to the submitted product/process.
• Special characteristics and known customer concerns are treated consistently across related documents.
• Any nonconformance, temporary control, deviation or interim condition is visible and formally dispositioned.
• Actions have owners, due dates and objective closure evidence where the source expects corrective action.
• The final conclusion can be independently repeated by another reviewer using the package alone.

09Source and limitations

Primary source: uploaded Production Part Approval Process (PPAP) Assessment / PPAP Submission Assessment, 15 pages, Quality-One. Source sections used on this page: PPAP Submission Assessment. Approximate source page coverage: 1-1.

This KEVOS chapter is an educational and assessment aid. It preserves the uploaded document's criteria but does not replace controlled customer-specific requirements, engineering specifications, contractual requirements or an official PPAP/APQP manual. Where the source references “PPAP 4th edition”, AIAG methods, Organization systems or Organization-specific targets, those references are retained as source context rather than silently updated or generalized.
