This study assesses the effect of some extended Enterprise Resource Planning (ERP) capabilities (Collaboration, Analytics, Web-portals, Add-ons) and ERP use on ERP value. The research conducted, followed a mixed-methods approach using an exploratory study (Delphi) and the resource-based view of the firm to understand the ERP capabilities and develop three competing models surrounding these capabilities, ERP use, and ERP value, and then a confirmatory study using a large-scale survey of firms in Germany, Portugal, and the United Kingdom, to test these models. Results suggest that the moderation model best explains the relationships, while the additive model highlights the direct effects of both ERP capabilities and ERP use on ERP value in an interesting way. Results highlight that the role of ERP use is more critical when moderating ERP capabilities and ERP value, as well as when additive to ERP capabilities, than when mediating between ERP capabilities and ERP value. The practical value of the study lies in the fact that this investigation provides new knowledge on how some extended ERP capabilities may positively influence value from investment, and together with ERP use, provide business value.

这项研究评估了某些扩展的企业资源计划（ERP）功能（协作，分析，Web门户，附加组件）和ERP使用对ERP价值的影响。进行了研究，然后采用了探索性研究（Delphi）和公司基于资源的观点的混合方法，以了解ERP能力并针对这些能力，ERP使用和ERP价值开发三种竞争模型。验证性研究使用对德国，葡萄牙和英国的公司的大规模调查来测试这些模型。结果表明，节制模型最好地解释了这种关系，而加性模型则以有趣的方式突出了ERP能力和ERP使用对ERP价值的直接影响。结果表明，在调节ERP能力和ERP价值以及增加ERP能力时，ERP使用的作用比在ERP能力和ERP价值之间进行调解更为重要。该研究的实际价值在于，该调查提供了有关扩展的ERP功能如何对投资价值产生积极影响的新知识，并且与ERP的使用一起提供了业务价值。
