The information technology subsystem plays a determinant role in the efficiency of enterprises. The main challenge in the design of this subsystem lies on “ systems integration”, as it is mandatory to cope with the large legacy of software tools. The systems integration task is however typically handled in ad-hoc manners, and customized for each enterprise. Here, the need for systems integration, its facets, levels and obstacles are first discussed. Then, a set of general steps to be followed for systems integration is suggested. Second, the suggested integration methodology approaches this problem at various levels of complexity, namely the cell / shop-floor integration, intra-enterprise integration, and inter-enterprise integration. Then, for every level of complexity, this chapter addresses the main applied technologies, typical solutions, main trends, and open challenges. These issues are discussed and exemplified in details.
