PPAP Validation Services
Before Customer Approval, Verify the Submission
A PPAP package may appear complete while still containing weaknesses capable of delaying approval, generating customer questions, triggering resubmissions, or creating risks during production launch. VyVy provides PPAP Validation Services to verify the accuracy, completeness, consistency, and technical integrity of Production Part Approval Process submissions before they reach the customer.

Global Manufacturing Coverage
The Production Part Approval Process is intended to demonstrate that customer requirements have been understood, manufacturing processes are capable, and production parts can consistently meet specifications under normal operating conditions.
For many organizations, preparing the PPAP package requires significant effort across engineering, quality, production, supplier management, metrology, and project management teams. By the time the package is assembled, there is often an assumption that the documentation accurately reflects the reality of the manufacturing process. That assumption is not always correct.
PPAP packages frequently contain inconsistencies between documents, incomplete supporting evidence, outdated studies, unsupported capability results, missing approvals, or validation activities that do not fully demonstrate process readiness.
VyVy provides PPAP Validation Services to verify whether the PPAP submission is technically sound, internally consistent, and supported by objective evidence before it is presented to the customer.

What Is PPAP Validation?
PPAP validation is a structured review of the documentation, studies, records, approvals, and supporting evidence included within a Production Part Approval Process submission.
The purpose is not to determine whether a project is ready for customer submission.
The purpose is to determine whether the submission itself can withstand technical scrutiny.
The review focuses on the quality of the evidence supporting the PPAP package and the consistency between the various elements included within the submission.
What Is Reviewed During PPAP Validation?
The scope is adapted according to customer requirements, submission level, product complexity, and project objectives.
Typical elements reviewed include:
Customer Requirements
Verification that customer requirements have been correctly interpreted and reflected throughout the PPAP package.
Drawing and Specification Alignment
Review of product characteristics, specifications, tolerances, and engineering requirements against supporting documentation.
Process Flow Documentation
Assessment of process flow diagrams and consistency with manufacturing operations.
Process FMEA
Review of risk analysis activities and alignment with process controls.
Organizations seeking a dedicated risk assessment may also benefit from our FMEA Audit Services.
Control Plans
Verification that identified risks and process controls have been correctly transferred into Control Plans.
Organizations seeking a broader evaluation of process controls may explore our Control Plan Audit Services.
Measurement System Analysis
Assessment of supporting MSA studies and measurement system suitability.
Organizations requiring a focused evaluation of measurement reliability may benefit from our MSA Audit Services.
Statistical Process Control
Review of capability studies, process performance evidence, and statistical analysis used to support PPAP approval.
Organizations seeking a deeper evaluation of statistical controls may also explore our SPC Audit Services.
Validation Records
Review of dimensional results, testing records, validation evidence, and supporting documentation.
Approval Documentation
Verification of approvals, sign-offs, customer requirements, and submission completeness.
Common Issues Identified During PPAP Validation
While every submission is unique, recurring issues often include:
- Inconsistencies between FMEA and Control Plans
- Missing supporting evidence
- Outdated capability studies
- Weak measurement system evidence
- Incomplete dimensional results
- Incorrect customer-specific requirements
- Inconsistent revision levels
- Unsupported process capability claims
- Missing approvals
- Validation activities not aligned with customer expectations
These weaknesses may not prevent submission, but they often create delays, customer questions, or requests for additional evidence.
Supplier PPAP Validation
Many organizations use PPAP validation to evaluate supplier submissions before accepting new components or approving suppliers.
The assessment can help identify weaknesses before they create risks within the supply chain.
Supplier PPAP validation may be particularly valuable for:
- New suppliers
- Critical components
- Safety-related products
- New manufacturing locations
- Supplier development projects
What Clients Receive

PPAP Validation vs PPAP Readiness Audit
Although the services are closely related, they address different objectives. PPAP validation focuses on the submission package itself. The review evaluates whether the documentation, evidence, studies, and approvals support the claims being made within the submission.
A PPAP Readiness Audit evaluates whether the broader organization, manufacturing process, project status, and launch activities are sufficiently mature to proceed with customer submission. Organizations seeking a broader assessment may also explore our PPAP Readiness Audit Services.
PPAP Validation vs APQP Audit
An APQP audit evaluates the planning activities used throughout product development and industrialization. PPAP validation focuses on the specific evidence used to demonstrate manufacturing readiness and customer requirements compliance. Organizations seeking a broader evaluation of project execution may benefit from our APQP Audit Services.
Why VyVy Audit?
A PPAP package can contain hundreds of pages of documentation. The challenge is rarely producing the documents.
The challenge is ensuring the evidence is complete, technically credible, internally consistent, and capable of supporting customer approval.
VyVy provides a structured review focused on the technical quality of the submission and the evidence behind it. The objective is to help organizations reduce avoidable delays, strengthen customer confidence, and improve the quality of the approval process.
Value Your Value.
Discuss Your PPAP Submission
Whether preparing for customer approval, reviewing a supplier submission, supporting a launch program, or managing a high-risk project, VyVy can help assess the technical strength of your PPAP package before it reaches the customer.
Frequently Asked Questions About PPAP Validation
When should PPAP validation be performed?
PPAP validation is typically conducted before customer submission, supplier approval, launch activities, or customer audits.
What is the difference between PPAP validation and PPAP readiness?
PPAP validation focuses on the submission package itself, while PPAP readiness evaluates whether the broader project and manufacturing process are ready for customer submission.
Can supplier PPAPs be validated?
Yes. Organizations frequently use PPAP validation to review supplier submissions before approving new suppliers or components.
Does PPAP validation include Core Tools?
Yes. Reviews commonly include FMEA, Control Plans, MSA studies, SPC evidence, and other supporting Core Tool documentation.
