To mitigate risks tied to a single supplier when securing vital components: Diversify suppliers: Source from multiple suppliers to reduce dependency. Negotiate backup agreements: Establish secondary suppliers or contingency contracts. Monitor supplier performance: Regularly assess reliability, quality, and risk factors. Stockpile critical components: Build safety stock to cover potential supply disruptions. Strengthen supplier relationships: Collaborate closely to address issues proactively and ensure priority access to resources.

Develop backup partnerships to lessen dependency and diversify your supply base to avoid risks associated with a single source. Use technology for real-time monitoring and keep safety supplies on hand to foresee and handle interruptions. Maintain solid working connections with suppliers and make sure you have emergency measures in place.

I would pursue joint ventures or co-development with suppliers to strengthen mutual reliability. Implementing supplier innovation programs can create additional value beyond cost. Using digital tools for real-time monitoring helps identify issues early. Strategic stockpiling agreements offer a buffer without excess inventory.

Diversify the supplier base to reduce reliance on a single important supplier. Negotiate preferential terms and conditions of contingencies in the contract. Implement strategic inventories on a short-term basis. Contingency plans should be formulated that involve alternative sources of supplies. Supplier performance monitoring should be regular. In that way, you will increase the supply chain's resilience and reduce its vulnerability due to disruption.

Single supplier sourcing strategy has to be managed in a proper way as the OEMs dependence on supplier is more rather than the converse. Hence if vital components are sourced its necessary that the agreements and contracts are in place with clauses which protects the OEMs interests. Also a collaborator approach has to be followed in dealing with such suppliers to ensure there is no risks to your supply chain.
