Baseline Split Ratios and Minimum Volume Floors in Dual Sourcing
Maintain a 70/30 production split with strict monthly minimum volume floors to preserve secondary line yields and protect against idle overhead surcharges.
Baseline Split Ratios
Meaning
Allocation agreements among multiple qualified assembly partners reduce dependency on a single manufacturer. Known as baseline split ratios, these percentages define the division of total purchase orders assigned to each supplier during standard operations.
Sourcing Balance
Multisourcing strategies depend on clear split thresholds to sustain the financial viability of each participating assembly plant. When baseline split ratios are set too low for a secondary partner, that partner may struggle to achieve the economies of scale needed to remain profitable. Conversely, a dominant partner receiving the majority share maintains high utilization but presents a greater concentration of risk if production stalls.
Buyers adjust these targets during annual reviews based on supplier performance and component yield.
Production Distribution
Volume shifts occur when one factory encounters a disruption or fails to meet quality thresholds. Contractual clauses typically allow the buyer to deviate from the established baseline split ratios if a supplier fails to maintain the agreed yield rates or delivery schedules. The secondary factory must have the capacity to absorb the extra volume without delaying the overall product launch.
This capacity readiness is verified during the initial supplier audit and periodically tested through simulation exercises.
Contractual Obligation
Purchase commitments often bind the buyer to these split allocations unless specific force majeure or performance conditions are met. If total market demand drops, maintaining the baseline split ratios ensures that both manufacturers receive a proportional reduction in orders rather than one being cut off entirely. Such agreements protect the supplier’s initial capital investment in dedicated tooling and test equipment.
The balance of volume distribution remains a primary tool for securing supply continuity in multi-site production plans.
