Effective information and resource management are the most important factors driving businesses to success. In today's dynamic and turbulent global business environment, there is a strong need for organisations to be competitive under all circumstances. Enterprise Resource Planning (ERP) can be used as a strategic tool, helping companies to gain competitive edge by integrating all business processes and optimising available resources. While ERP systems are powerful packages, many companies are not fully satisfied with their systems, because ERP systems do not always fulfil all company’s business needs. This work is meant to promote ERP systems by presenting one of them – the MFG/PRO by QAD, discussing its common and unique properties, sharing particular working experience and proving that this ERP system can be perfectly adapted to suit the needs of all companies. New methods for adaptation of ERP system according to organizational needs have been developed. Methods incorporate database, application and user interface modifications. Implemented modifications caused a reasonable improvement in MFG/PRO’s capabilities.
