An organization that has a well-designed information system will generally have a competitive advantage over an organization with a weaker system. However, the facts show that the implementation of an information system is not easy. The more departments related to the information system, the more complex the information system will be and the higher the risk of failure. This research takes a case study of the effectiveness of information system implementation at PT Samudera Mulia Abadi (SMA) and what factors influence it.
