Focused on the results obtained in our research, it can be verified that the intention of use of Big Data by the companies is determined: 1) by the perception of obtaining good results with the implementation of this technology (PE); 2) by the positive effect that they mean in this technology that others consider important to use (SI); and 3) mainly by the fact that the company facilitates the support and the resources to promote its use (FC). This last relationship was not contemplated in the original UTAUT (Venkatesh et al., 2003) and was contemplated in UTAUT 2 (Venkatesh et al., 2012). On the other hand, it is seen that the intention of use is negatively affected by the resistance to the use of new technologies that exists in any organisation, although its influence is lower than the previous relations, as Hsieh (2015) presented. It can also be seen that, although the use of Big Data is perceived as difficult (EE), this influence is very low and not very significant on the intention of use.
