In today's global free-trade environment, most industries have to increase their potential in order to increase their competitiveness. It is known that successful implementations of the Enterprise Resource Planning system or ERP system in an organization can enable company personnel resources to improve their efficiency and effectiveness. However, not all organizations have achieved or been successful with ERP implementation. Also, it possibly generates new problems in the organization. The objective of this research is to investigate the problems and causes of unsuccessful ERP implementation in order that the obtained results can be used as guidelines for organizations that are requiring the ERP system. The research was initially conducted by in-depth interviews of the top management of research focused industries comprising 25 companies in order to study the companies' background and their business process. This was followed by management training and workshops on the business process writing and process improvement with the company project teams. Finally, following a discussion with top management and project teams, the organization can generate the to-be or expected business process. The results of the research shows that companies who have not implemented the ERP system are now encountering the following problems: top management do not understand or recognize the benefits of the ERP system, the company business process is not efficient and unable to integrate with the ERP system. Furthermore, the company does not know how to prepare and adjust to the ERP project. Of those organizations who are currently implementing the ERP system, most are encountering problems of inefficiency and not fully utilized ERP system to its potential such as inaccurate data, unreal time data, unreliable data and inconsistency of requirement data, and so on. The above results can then be used as supporting information for organizations on how to prepare themselves before implementing the ERP system and how to solve their ERP related problems.
