DVP Plans

DVP plans: the strategic guide to component qualification in automotive and aerospace

How supplier self-qualification ensures standards of excellence and durability in high-performance industries

Ensuring the quality of a component or material means not only producing it correctly, but certifying its durability through rigorous protocols. AQF (Supplier Self-Qualification ) plans, also known as SSQ (Supplier Self-Qualification) plans, or DVP (Design Verification Plan) are now the standard of excellence for the luxury automotive, aerospace and defense sectors, where aesthetics must necessarily marrytechnical reliability. SIDEIUS transforms these complex plans for suppliers of materials and components into a structured validation process.

What are DVP plans?

The acronym DVP identifies the supplier’s self-qualification procedure. In this model, the manufacturer of the part is not limited to manufacturing, but takes responsibility for its technical qualification. The supplier ensures that the part meets the specifications required by the end customer through rigorous testing. Although born in the luxury automotive sector, these plans are now also essential inaerospace and defense, especially for polymeric materials, carbon fiber composites, and surface coatings.

What is the main objective of an DVP plan?

The goal is to ensure the operational life of the medium, usually estimated at about ten years. DVP is used to prevent returns from the market and customer dissatisfaction by intercepting design or manufacturing bugs prior to release. Testing verifies the component’s ability to react properly to thermal, chemical, and physical stresses, preventing both structural failure and aesthetic defects such as dulling or staining.

What evidence typically makes up a qualification plan?

The packages are extremely diverse and include:

Environmental tests: solar aging, humidity, thermal shock, and corrosion resistance.
Characterization of coatings: tests for hardness, adhesion (cross-cut test), impact resistance, chip resistance, abrasion and thickness.
Chemical resistance: contact and immersion with aggressive agents such as oils, acids, bases or common consumer products such as sunscreens and deodorants.
Materials analysis: structural testing on polymers and fibers, mechanical characterization, and flammability testing.

What are the competitive advantages of relying on a single partner?

The main advantage is the reduction in management complexity. SIDEIUS operates as a single point of contact, taking full responsibility for the project and acting as “construction manager.” The company coordinates in-house laboratories (which cover about 80-90% of the testing) and manages any qualified partners for the remaining 10%, relieving the client of the need to interface with multiple suppliers and ensuring a complete and specific response.

What are the main specifications covered by DVP plans in SIDEIUS?

Plan management requires full mastery of the technical specifications of major OEMs. Key specifications managed and covered within our workshops include:

Volkswagen Group: TL 211, TL 226, TL 52680.
Stellantis / FCA: 9.55253, 9.55842/01, MS.90089, MS.90102, MS.50158.
General Motors: GMW 14650, GMW 14797.
Other luxury standards: MSL.10.23.0007 and DBL 5425.

What are the operational steps of management in SIDEIUS?

The process begins with an analysis of the customer’s technical specification. SIDEIUS checks the feasibility of each request against the geometry and material of the part. If a request is found to be unfeasible (e.g., a flat surface test required on a curved component), proposals for technical modification are developed. Once the details and number of samples are agreed upon, the bid is formulated and the tests are performed in our laboratories.

How is the dedicated work team structured?

In SIDEIUS, this is managed by a fully dedicated resource who serves as a collector of activities. This coordinator is supported by a cross-functional team whose expertise enables them to meet the needs required by the plan in several areas: the material testing laboratory (physical, mechanical, and chemical testing), the area for nondestructive testing (NDT such as tomography and liquid penetrant), and the functional testing department.

What happens if a component fails a test of the DVP plan?

Failure of a test is not just a negative outcome, but anopportunity for improvement. In the case of nonconformity, aroot cause analysis (root cause analysis) is initiated together with the customer. With the technical expertise of the laboratory technicians, it is possible to identify whether the problem lies in the component’s manufacturing process, surface treatment, or chemical composition of the material, allowing the supplier to reevaluate certain aspects of production and evaluate possible design revisions with its customer.
