Prioritize measurable metrics and integration:

Key factors are proximity to ports and air hubs, seasonal road reliability, carrier density, and cross-dock availability. These determine landed cost, lead-time variability and the need for safety stock or expedited lanes.

Require OTIF, order accuracy, inventory accuracy, average pick/pack time and dock-to-ship cycle metrics, delivered with weekly dashboards and API access. Include contractual remedies for repeated SLA breaches.

Assess seasonal access windows and build contingency capacity: maintain buffer stock, contract alternate carriers, and specify certified temperature-controlled storage and validated handling procedures to protect product integrity.
