# Alpha memo: supply resilience performance cross-context signal
**One-sentence alpha:** A methodologically incommensurable pair of 2023 supply-chain-resilience papers offers a bounded empirical positive link from one and a context-dependent decision framework from the other, so the SCR–SCP nexus is consistent with a positive association only on Receipt 2's Ghanaian manufacturing survey, while Receipt 1 is methodological.
**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 decision model as an automotive case study to rank resilient supplier-selection criteria during COVID-19 and does not estimate an empirical resilience–performance relationship.
**Receipt 2:** Supply chain resilience and performance of manufacturing firms: role of supply chain disruption (Journal of Manufacturing Technology Management, 2023) — PLS-SEM on a sample of 345 of 2,495 manufacturing firms in Accra, Ghana, reports that supply chain resilience (SCR) has a significant positive effect on supply chain performance (SCP), and that supply chain disruption (SCD) components — supply disruption, catastrophic disruption, and infrastructure disruption — significantly moderate the SCR–SCP nexus, with a negative coefficient for catastrophic disruption indicating heterogeneous moderation across SCD components.
**Why this is surprising:** Receipt 1 makes the resilience–performance space look methodologically mature for cross-context inference, yet it actually supplies no effect estimate, so the entire empirical "positive association" rests on Receipt 2's single Ghanaian survey, and the moderation direction is not uniform across SCD components.
**Caveats/falsifiers:**
- Population is bounded to 345 Ghanaian manufacturing firms in Accra, an automotive AHP–VIKOR case study in Receipt 1, and SCD components (supply, catastrophic, infrastructure) show heterogeneous (including negative) coefficients; future replication in a different industry or region with a non-supply-disruption moderator as null would directly falsify the cross-context positive pattern.
- Receipt 1 is methodological (no empirical SCR–SCP effect) and Receipt 2 is single-country cross-sectional with PLS-SEM on 345 firms, so the moderator hypothesis remains tentative and confounded by industry, geography, and SCD-component heterogeneity; no operational or managerial equivalence across the two settings is implied.
