The best practices in supplier selection and qualification
3.1. The most important criteria and KPIs when qualifying camshaft position sensor vendors
Supplier qualification is a process that is typically started by purchasing and/or quality-management professionals and teams within OEMS or by a distributor or reseller when evaluating different manufacturing vendors. For Tier 1 suppliers, such a qualification process may include the following steps:Verification of existing registrations and/or certifications (ISO 9001, IATF 16949, etc.) as well as full audit and remediation action reports.
Evaluation of production capacity and scalability for a particular part or module production and for the market segments of interest to the buyer.
Available and ongoing investments in R&D and product technology development, including alternative technologies, materials, miniaturization, or special tools, etc.
Supplier risk scoring, credit analysis, and financial-stability evaluation.
Typically, there is also a stage-gate process to approve each of the steps and suppliers often get to know potential end customers through third-party business-matchmaking or B2B networking events.
3.2. Sampling and pilot runs
A formal qualification process is often followed by the small pilot runs to confirm production consistency and qualification as well as to ensure that the vendor¡¯s tooling and engineering are fully aligned with the part numbers, specifications, and packaging selected by the customer.
3.3. Contract negotiation and terms, conditions, and SLAs
Contract negotiations will focus on pricing and pricing tiers for annual minimum volume commitment, as well as defined service-level agreements (SLAs) that are agreed between the OEM and the Tier 1 supplier (SLAs between distributors and manufacturers are also common). Other typical points include warranty coverage for material and workmanship as well as clear return-material-authorization (RMA) process and terms.
- Quality control and traceability
4.1. Incoming inspection and testing
Incoming quality control (IQC) typically performed by OEMs and distributors can include visual inspections for corrosion and any potential damage during shipment as well as electrical testing of signal amplitude and switching threshold as well as overall noise immunity.
4.2. Production line quality controls
Inline quality controls performed during the production can include automated visual inspection (AVI) to ensure proper component placement and alignment, connector placement and tightness, as well as functional testing using a mechanical part that simulates a rotating reluctor wheel or disk at various speeds (idle, half-throttle, full-throttle, etc. ).
4.3. Final acceptance tests and environmental testing
Environmental tests such as thermal shock, salt spray/humidity testing, and vibration to various frequency ranges are required to simulate the real-world vibration and operating temperatures, as well as any potential shock.
4.4. Lot tracking and serialization
The key elements of effective traceability practices in case of field returns or RMA warranties are associated with specific part numbers for individual production lines and include lot or batch numbers and date codes.
- Logistics and distribution for camshaft position sensors
5.1. Inventory management models
Consignment stock programs, just-in-time (JIT) inventory, and vendor-managed inventory (VMI) are some of the most common inventory management models used by global distributors and manufacturers.
5.2. Packaging, shipping, and freight optimization
A typical approach to international freight is to develop packaging that can be easily palletized for transit to key destinations in both export and import and to try to consolidate freight whenever possible to make full container loads (FCL) to reduce the freight rates.
5.3. Customs compliance and duties
Correct HS coding and classification of camshaft position sensors for import and export and having the correct certificates of origin are also needed for any global shipments to comply with import and export controls of both supplier and distributor/importer countries.
- Risk management and business continuity planning
6.1. Supply-chain redundancy and diversification
Supply-chain redundancy can include qualification of multiple production sites as well as secondary or backup suppliers for key subcomponents and parts to ensure supply continuity, as well as proper safety-stock buffers.
6.2. Monitoring regulatory and geopolitical changes
Supply-chain risk-management should also include close monitoring of regulatory as well as geopolitical developments such as export/import restrictions and trade policy changes to stay ahead of possible restrictions or increased costs of transportation.
6.3. Cybersecurity and data protection
Global supply chains are highly interconnected, and all companies rely on digital data, documentation, and systems to share information. Ensuring that intellectual property and data privacy are also appropriately protected is a critical function of cybersecurity and is typically combined with data-integrity assurance.
- Value-added services for distributors and resellers
7.1. Technical support and installation training
Effective technical support can be a critical differentiator for suppliers who have the knowledge and resources to share with customers. This can include in-country installation workshops, product demonstration, and diagnostic trainings as well as online support and training.
7.2. Marketing and branding support
Co-branding, if this is allowed under the global supplier¡¯s quality-management systems and IP or trade-mark registration, as well as joint marketing, sales and technical-support material development and production are other examples of effective value-added services for distributors and resellers.
7.3. After-sales service and warranty management
Online portals for the management of RMA, efficient return processing with access to advanced replacement, RMA tracking and documentation are the most common ways that aftermarket suppliers support their distribution channel partners and R&D and product program investments and development cycles. OEMS may require their distributor partners to have a minimum number of years of in-country presence and other requirements to be a trusted partner.
