Supply-chain evidence should show how a supplier will fulfil the proposed order under the conditions you expect. A headline capacity figure is difficult to use unless it relates to the product, process, available production time and materials required for your delivery.
Trace the route to delivery
Ask which site will manufacture or handle the goods and which stages depend on subcontractors. Review the production schedule, material lead times and constraints affecting the proposed quantity. Separate nominal capacity from capacity that is available during the requested period.
Request records relevant to comparable deliveries and the checks used to release goods. Understand how the supplier identifies batches, investigates shortages and reports changes. Evidence from a different product or site may provide context without establishing suitability for this order.
Review continuity and handover
Identify materials, transport routes and facilities that have limited alternatives. Ask how the supplier would communicate a disruption and what recovery arrangements can actually be used. An alternative listed in a presentation is less useful than one assessed for the same specification.
Carry the agreed lead times, packaging, release records and delivery responsibilities into the order. Record remaining assumptions and the people who will monitor them. Review the evidence again when the production site, critical material or fulfilment route changes.
