Furniture enterprises combine digital resources, external knowledge, and strategic adaptation in different ways when developing products. This study examines configurations of digital capability, external collaboration, and strategic flexibility associated with product innovation success among 60 rattan-furniture enterprises in Trangsan, Sukoharjo, Indonesia. The comparative configurational study was conducted during September–December 2025, with questionnaire indicators referring to September 2023–August 2025. Twenty five-point items were aggregated into four constructs and calibrated using direct logistic anchors of 2, 3, and 4. Fuzzy-set qualitative comparative analysis examined necessity, sufficiency, the outcome complement, and sensitivity to analytical choices. No individual condition or its negation reached a necessity consistency of .90. High innovation success was associated with two configurations: external collaboration combined with strategic flexibility, and digital capability combined with strategic flexibility. Solution consistency was .808, coverage was .709, and proportional reduction in inconsistency was .700. The outcome complement followed different configurations, indicating asymmetric associations. Several threshold changes preserved the success solution; however, excluding 15 condition-crossover cases removed the collaboration pathway. The findings suggest that strategic flexibility connects internal digital resources or external collaboration with innovation success, while remaining distinct from an individually necessary condition. The cross-sectional, self-reported design and calibration sensitivity limit causal interpretation and generalization beyond the participating enterprises.
