Requirements

• ☐ Define requirements: drawings, specs, tolerances, materials, finishes, volumes, demand profile, lead times, packaging, compliance
• ☐ Segment parts/suppliers: complexity, criticality, spend, forecast stability, make/buy, regional risk
• ☐ Build supplier shortlist: relevant fabrication capability, similar applications, capacity, location, certifications, financial stability
• ☐ Assess technical capability: laser/punch/form/weld/assembly, tooling, inspection, prototyping, engineering support, NPI readiness
• ☐ Verify quality system: ISO status, control plans, FAI/PPAP needs, traceability, NCR/CAPA process, incoming and final inspection
• ☐ Check cost structure: piece price, tooling/NRE, setup charges, scrap, packaging, freight, duties, payment terms, should-cost
• ☐ Evaluate supply reliability: capacity, OEE, bottlenecks, surge ability, secondary equipment, subcontracting control, continuity plans
• ☐ Review compliance and risk: labor, ESG, RoHS/REACH, conflict minerals if applicable, cybersecurity, insurance, business continuity, geopolitics
• ☐ Request and compare samples: prototype/first articles, fit/function, dimensional reports, cosmetic standards, assembly accuracy
• ☐ Conduct supplier audit: process flow, material handling, welding/fabrication controls, calibration, maintenance, warehouse, EHS
• ☐ Score and select: weighted scorecard covering quality, cost, delivery, capability, risk, communication, innovation
• ☐ Negotiate contract terms: pricing, MOQ, Incoterms, lead times, change control, warranty, IP, confidentiality, penalties/service levels
• ☐ Lock specifications: approved drawings, BOM, revision control, packaging, labeling, acceptance criteria, test methods
• ☐ Set up onboarding data: supplier master, contacts, bank details, tax, ERP/EDI, ordering and invoicing requirements
• ☐ Agree operational KPIs: PPM, on-time delivery, lead time adherence, responsiveness, yield, cost-down, corrective action closure
• ☐ Define launch plan: pilot run, ramp-up milestones, approval gates, contingency source, inventory buffer, communication cadence
• ☐ Establish governance: regular QBRs, scorecard reviews, escalation path, continuous improvement and cost-reduction roadmap

Best practices

• 1. Define exact requirements, including material, thickness, tolerances, finish, and load/environment conditions.
• 2. Provide complete CAD drawings, BOMs, and revision control before requesting quotes.
• 3. Verify supplier capabilities for cutting, bending, welding, assembly, and finishing in-house or through approved partners.
• 4. Review certifications and quality systems, such as ISO, material traceability, and inspection documentation.
• 5. Compare total cost of ownership, not just unit price, including tooling, scrap, rework, freight, and lead time.
• 6. Confirm manufacturability early to avoid design issues that increase cost or delay production.
• 7. Request samples, prototypes, or first-article inspection before committing to volume orders.
• 8. Establish clear quality acceptance criteria, inspection methods, and nonconformance procedures.
• 9. Validate material sourcing and ensure compliance with required standards, regulations, and country-of-origin needs.
• 10. Assess production capacity and lead-time reliability, especially for recurring demand or seasonal spikes.
• 11. Require robust packaging, labeling, and handling standards to prevent damage in transit and storage.
• 12. Put change management in place so any design, material, or process change is approved before release.
• 13. Evaluate supplier communication, responsiveness, and order visibility for smoother procurement execution.
• 14. Use supplier scorecards to track quality, on-time delivery, cost, and corrective-action performance.
• 15. Build long-term partnerships with suppliers that can support engineering changes, scale-up, and continuous improvement.
