Delta Electronics is conducting a detailed cost analysis of its two primary suppliers, VoltStream Inc. and CircuitHub Ltd., to evaluate their performance and costs associated with the supply of a key electronic component used in their products. Delta Electronics has been sourcing from these suppliers for several years. VoltStream Inc. provides a higher volume of orders at a lower cost per unit, while CircuitHub Ltd. offers a smaller volume at a higher cost per unit. Previous Year's Data: * Delta Electronics purchased 25,000 units from VoltStream Inc and 15,000 units from CircuitHubLtd. * The company places orders with VoltStream Inc. at $10 per unit and with CircuitHub Ltd at $12 per unit. * The ordering cost for both suppliers is $200 per order, and the annual holding cost is $2 per unit.

Discuss any recommended actions for the company, and please explain your reasoning. Assuming delta electronics is considering a shift towards a more agile supply chain mode, from an EOQ (economic order quantity) model to a JIT (just-in-time) system, analyse how this transition would affect the supplier- related costs. Discuss which supplier would be more suitable for this transition and explain why
