Quantifying Initial Unit Cost Premiums in Split Hardware Sourcing Allocations
Split hardware sourcing increases initial unit costs by 12 to 38 percent through volume tier loss, duplicate tooling, and secondary line qualification.
Dual Sourcing Volume Tier
Meaning
Splitting procurement volumes among suppliers requires setting up distinct quantity allocations. The mechanism of a dual sourcing volume tier divides the total production order of a component into specific quantity levels for primary and secondary vendors. It governs the per-unit pricing based on the purchasing volume allocated to each source.
This tiering system does not apply to single-source components or custom parts with only one qualified fabrication facility.
Contractual Structure
Sourcing contracts establish the specific limits and pricing for each purchase level. Procurement officers deploy a dual sourcing volume tier to balance cost-saving incentives against the security of having two suppliers. By defining these levels in advance, the buyer avoids renegotiating prices when order volumes fluctuate.
This pricing framework aligns supply chain priorities with operational budgets.
Procurement Flexibility
Component buyers change their purchasing distribution based on supplier performance and factory capacity. Under a dual sourcing volume tier, the buyer can shift volumes from an underperforming primary vendor to a more reliable secondary source. If a supplier fails to meet quality standards, the buyer uses the pre-defined pricing of the alternate tier to execute the transfer.
This adjustment occurs without interrupting the overall manufacturing schedule.
Financial Impact
Price per unit is directly affected by the volume commitments made to each manufacturer. When a company splits its orders, it loses the discounts of a single high-volume purchase. However, the use of a dual sourcing volume tier mitigates this loss by establishing clear bulk pricing bands for both suppliers.
To optimize expenditure, supply chain managers calculate the optimal distribution of orders across these tiers to minimize the total cost of ownership. This strategy keeps material expenses within forecasted limits. It also prevents surprise cost increases from a secondary vendor who would otherwise charge a high premium for low-volume runs.
