TL;DR

Supplier Concentration Risk Framework structures setting supplier concentration thresholds decisions by tying supplier share, lead time variability, and quality defect rate to contract terms, dual-source feasibility, and inventory buffers and forcing a clear call on cost efficiency versus resilience. The output is a governance-ready decision record.

Applicability

Best for situations like single-source dependence after a merger where setting supplier concentration thresholds depends on supplier share, lead time variability, and quality defect rate plus contract terms, dual-source feasibility, and inventory buffers. It turns the cost efficiency versus resilience tradeoff into explicit criteria and sets review checkpoints and escalation paths.

Steps

1. Define scope, horizon, and decision owner, then standardize definitions for supplier share, lead time variability, and quality defect rate so comparisons remain consistent.
2. Gather inputs for contract terms, dual-source feasibility, and inventory buffers, document data quality gaps, and align timing and units with the metrics.
3. Model scenarios to test how cost efficiency versus resilience shifts under plausible ranges; record trigger thresholds.
4. Select the preferred option, capture constraints and approvals, and summarize the decision criteria in one place.
5. Publish monitoring cadence and review triggers tied to changes in supplier share, lead time variability, and quality defect rate and contract terms, dual-source feasibility, and inventory buffers.

Template

Template: Objective and decision question; Scope and horizon; Metrics (supplier share, lead time variability, and quality defect rate); Key inputs (contract terms, dual-source feasibility, and inventory buffers); Scenario ranges and trigger points; Options A/B/C with cost efficiency versus resilience implications; concentration heatmap and mitigation plan; Risks and mitigations; Decision criteria; Recommendation; Owner and timeline; Review triggers; Evidence log and data refresh plan.

Pitfalls

• Treating supplier share, lead time variability, and quality defect rate as sufficient without validating contract terms, dual-source feasibility, and inventory buffers creates false confidence and weakens the decision.
• Overweighting one side of cost efficiency versus resilience leads to policies that break when conditions shift.
• single-point-of-failure exposure if data ownership or refresh cadence is unclear.

Case

Case: In a manufacturing operation, leaders faced single-source dependence after a merger and needed to decide setting supplier concentration thresholds. Using the Supplier Concentration Risk Framework, they aligned supplier share, lead time variability, and quality defect rate with contract terms, dual-source feasibility, and inventory buffers, mapped where cost efficiency versus resilience flipped, and documented trigger points and guardrails. The decision record shortened escalation cycles, improved cross-functional alignment, and was reused in the next planning review. They also defined a review calendar and contingency actions to keep the policy resilient.
