A four-round, advanced strategic-sourcing simulation set inside Cumberland Health Brands (CHB), a Nashville USD 820M consumer-health manufacturer that outsources nearly all warehousing, fulfillment and transport to its 3PL, Apex Logistics Solutions, under a nine-year transactional contract worth USD 64M/year — CHB's single largest indirect spend.
In May 2026 a peak-season fill-rate collapse to 88% (target 98%), ~USD 3.1M of chargebacks and expediting in one quarter, and a CFO mandate to take 12% (USD 7.7M run-rate) out of logistics within 18 months force the relationship into the open.
The deal's defining flaw: every dollar Apex saves CHB through efficiency reduces Apex's own revenue, so a stalled warehouse-automation project that would cut billable picks ~18% (and Apex revenue ~USD 4.8M/year) has sat frozen for a year. The contract auto-renews in 90 days; the only BATNA is a re-bid costing USD 6–9M over 9–12 months with real service risk.
Playing the Sourcing/Category Manager, you (1) DIAGNOSE the failure as a contract-design problem — misaligned economics and adversarial incentives — not a performance problem to punish harder, and decide whether this is a transactional spend to optimize or a strategic relationship to transform; (2) CHOOSE the contract model along Vitasek's Sourcing Business Model continuum — transactional squeeze, performance-based, or Vested (outcome-based, shared-value); (3) DESIGN the shared-value gainshare and Hart/Frydlinger relational governance — an agreed baseline with open-book transparency, outcome (not activity) scoping, a joint governance body, and a way to handle the unforeseen relationally; and (4) NEGOTIATE & DEFEND the joint proposal to Apex's account executive and CHB's CFO, proving the USD 7.7M is real, the win-win credible, and the re-bid BATNA honestly priced.
The math rewards transforming a strategic dependency into an aligned, outcome-based deal with a measured baseline and credible governance — and punishes the five classic errors: the squeeze reflex that deepens the misalignment, Vested-in-name-only relational vocabulary over untouched pay-per-pick economics, specifying the 'how' and locking out the supplier's innovation, gainsharing with no agreed baseline or open-book, and bluffing a re-bid the supplier can see is a 9–12 month, USD 6–9M reality.
Final KPIs track Run-Rate Savings (USD M vs the USD 7.7M mandate), Incentive Alignment, Relationship & Governance strength, and Deal Risk (dispute, service, BATNA and renewal exposure).
