PurposeThis research aims to improve supply chain management performance through the successful usage of ERP system. This can be through investigating the relationship between enterprise resource planning (ERP) system and supply chain management (SCM) performance in the context of Malaysian manufacturing companies that use ERP system.Design/methodology/approachThe questionnaire survey was posted to the Malaysian manufacturing companies that are using ERP system in order to investigate the relationship between ERP system and SCM performance. The respondents of this study were the MIS or IT executives. A total of 80 usable responses were received and used in the analysis.FindingsThe findings of this research indicated that there is a positive and significant relationship between ERP system i.e. (integration, material management, production planning, and controlling), and SCM performance. The workflow management, however, does not have a significant relationship with SCM performance. The findings of this study imply that the successful implementation and the effective usage of ERP system can contribute toward enhancing supply chain management performance in many ways such as, integration of internal business processes, enhancement of information flow among different departments inside the company, improvement of the company's relationships and collaboration with outsourcing suppliers, customers, and supply chain partners.Research limitations/implicationsThis research focuses only on post‐implementation of ERP system life cycle, where ERP system passes through three implementation stages of system life cycle and that includes pre‐implantation stage, implementation stage, and finally post‐implementation stage. Two or three stages of ERP system life cycle could be investigated simultaneously.Practical implicationsThere should be many success records in ERP system and this is to prove to companies that ERP systems can contribute toward improving their overall business performance. Therefore, this research encourages companies to adopt ERP systems and then contribute to technology diffusion. The finding of this study supports this justification and records a new success of ERP systems in Malaysian manufacturing companies.Originality/valueThe results of this study will enable companies to achieve optimum usage of ERP system after the implementation stage and help to avoid system failure and achieve better SCM performance. The study contributes toward technology diffusion between companies through reducing the likelihood of ERP systems failure, and therefore introduces ERP systems to other manufacturing companies in Malaysia.
