Intención de adopción de big data en la cadena de suministros: Una perspectiva brasileña

Autoría SCIMAGO INSTITUTIONS RANKINGS

RESUMEN

Las aplicaciones de big data han estado remodelando varios modelos de negocios y han provocado fuertes transformaciones en la cadena de suministro (CS). Con el apoyo de la literatura de big data, CS y la teoría unificada de aceptación y uso de la tecnología (UTAUT), este estudio tiene objetivo evaluar las variables que afectan a los profesionales brasileños para adoptar big data. Por lo tanto, adaptamos y validamos un modelo UTAUT previamente desarrollado. Un total de 152 encuestados de CS revelaron que las condiciones de facilitación (por ejemplo, la infraestructura de TI) tienen una gran influencia en la adopción de big data. Por otro lado, la influencia social y la expectativa de desempeño no mostraron un efecto significativo. Este estudio contribuye a la práctica, con información valiosa para los responsables de la toma de decisiones que están considerando proyectos de big data. Además, ayudamos a minimizar la brecha con respecto a los estudios de big data en el contexto brasileño.
