Requirements

• Define scope and specs; confirm product categories, dimensions, performance requirements, finishes, glazing types, codes, and standards.
• Align on sourcing strategy; decide make/buy, single vs. multiple suppliers, local vs. regional vs. global, and preferred sourcing model.
• Prequalify suppliers; review capability, capacity, certifications, financial stability, references, safety record, and legal compliance.
• Assess technical fit; verify product engineering, customization ability, testing data, thermal/acoustic/fire/security performance, and installation support.
• Evaluate quality systems; inspect QA/QC process, defect rates, traceability, warranty terms, and corrective action history.
• Check supply reliability; review lead times, on-time delivery, production flexibility, inventory strategy, and contingency plans.
• Compare total cost; include unit price, freight, duties, handling, packaging, storage, installation, maintenance, and lifecycle cost.
• Review commercial terms; negotiate payment terms, pricing structure, escalation clauses, MOQ, change-order rules, and incoterms.
• Confirm logistics readiness; validate packaging, breakage controls, delivery scheduling, site access, and last-mile handling.
• Assess sustainability and compliance; check ESG practices, recycled content, energy performance, emissions, and documentation requirements.
• Run sample and pilot orders; test fit, finish, performance, and installability before full award.
• Validate onboarding requirements; set up vendor master data, contacts, PO process, invoicing, document submission, and escalation paths.
• Define SLAs and KPIs; track lead time, defect rate, breakage rate, responsiveness, claim closure, and delivery accuracy.
• Establish governance; assign owner, approval workflow, review cadence, risk register, and supplier scorecard.
• Plan for continuity; identify backup suppliers, alternate materials, substitute options, and emergency sourcing triggers.
• Start with a controlled rollout; monitor early orders, capture lessons learned, and refine the sourcing plan.

Best practices

• 1. Define exact performance requirements up front: thermal, acoustic, security, fire rating, wind load, and durability.
• 2. Match products to the building use case: office, industrial, retail, healthcare, hospitality, or multifamily.
• 3. Verify compliance with local codes, standards, and certification requirements before purchase.
• 4. Request full technical submittals, including drawings, test data, warranty terms, and maintenance requirements.
• 5. Compare total cost of ownership, not just unit price, including installation, upkeep, energy savings, and replacement cycle.
• 6. Evaluate supplier manufacturing capacity, lead times, and delivery reliability.
• 7. Confirm material quality and glazing specs, including frame system, glass type, coatings, spacers, and hardware.
• 8. Assess installer qualifications and require experienced, manufacturer-approved installation teams.
• 9. Plan for lifecycle maintenance, cleaning, repairability, and availability of replacement parts.
• 10. Prioritize energy efficiency and sustainability, such as low-E glass, thermal breaks, and recyclable materials.
• 11. Require robust security and access-control compatibility where needed, especially for high-traffic or sensitive sites.
• 12. Inspect sample units or pilot installations before committing to large-volume orders.
• 13. Build in contingency planning for damage, breakage, site conditions, and schedule delays.
• 14. Use clear SLAs, warranties, and service agreements covering defects, response times, and after-sales support.
• 15. Standardize specifications across projects where possible to simplify procurement, reduce risk, and improve consistency.
