摘要:The open source ERP systems are beginning to take a significant market share of ERP in SMEs. They are supported and developed by several actors: open source editors and communities. The purpose of this study is to examine the risk factors in the relationship of open source ERP editors and their partners (i.e., the information technology (IT) services companies). Three exploratory case studies on partnership relations between ERP editors and IT services companies are carried out by relying on a qualitative method of collecting and analyzing data. The results show the existence of several of risks in such a relationship: the risk of fork, the risk of opportunistic behavior, the risk of conflict, the risk of absorption, the risk of non-appropriation, and finally the risk differences of objectives. These results confirm the risk factors already found in the literature in strategic alliances. This research is based on a qualitative approach, therefore reducing its generalization. In terms of managerial implications, this research creates awareness among leaders of IT services companies, who wish to become a partner of ERP open source editor, to the risks involved in such collaboration. Open source Software and particularly open source ERP systems are a modern phenomenon. This paper examines the relationship between open source ERP editors and their partners in terms of risk, whereas the literature on risk factors focuses only in the world of proprietary software (or commercial).
