# Alpha memo: supply resilience performance translation boundary
**One-sentence alpha:** Receipts suggest a supply-resilience-to-performance link that is detectable across automotive and Ghanaian manufacturing contexts but is bounded by disruption-type, firm-population, and modelling choices rather than biology-level generality.
**Receipt 1:** Evaluating Supply Resilience Performance of an Automotive Industry during Operational Shocks: A Pythagorean Fuzzy AHP-VIKOR-Based Approach (Systems, 2023) — proposes a two-stage Pythagorean fuzzy AHP–VIKOR hybrid model on an automotive case study to rank resilient-supplier-selection criteria under COVID-19 shocks.
**Receipt 2:** Supply chain resilience and performance of manufacturing firms: role of supply chain disruption (Journal of Manufacturing Technology Management, 2023) — reports PLS-SEM on 345 Accra-metropolis manufacturing firms, finding supply chain resilience has a significant positive effect on supply chain performance and that supply chain disruptions (supply, catastrophic, infrastructure) positively moderate this relationship.
**Why this is surprising:** Receipt 1 framed resilience–performance as a fuzzy-MCDM supplier-selection problem in one automotive case, whereas Receipt 2 reframes the same link as an econometrically moderated firm-level effect, indicating the relationship persists but its drivers and boundary conditions differ by context.
**Caveats/falsifiers:**
- Receipt 1 is a single automotive case study using fuzzy MCDM; Receipt 2 is cross-sectional survey evidence from 345 Ghanaian manufacturing firms, so the two contexts differ on population, geography, and methodology — the moderator hypothesis (disruption-type vs. operational shock) is tentative and confounded by these axes, yielding a heterogeneous cross-context signal rather than a direct replication, and no clinical, dosing, or supplementation recommendation follows.
- The 345-firm sample is moderate but drawn only from the Accra metropolis, limiting generalizability; Receipt 1's criteria weights depend on expert nominal-group input rather than observed performance, so a decisive falsifier would be a multi-region panel dataset showing the resilience–performance slope attenuating once firm-level and region-level confounders are jointly modeled.
