Many large original equipment manufacturers have long been ruthless with their suppliers, demanding extremely low prices and loading them up with risks.

They include moving beyond their transactional behavior and treating suppliers more like partners, implementing greater price flexibility in contracts, and rethinking inventory levels and where in the supply chain stock is carried.
The resilience of a supply chain is dependent on the reliable performance of the suppliers who make it up, but the fiscal health of many of lower-tier firms is not visible to executives at companies several tiers up. It's important for original equipment manufacturers to have many lower tier suppliers.
