Implementation of functions and their integration with information systems (IS) is important for successful factory operation, and many IS (ERP and other IS) are used in such facilities. Implementation and combinatorial pattern of functions have certain similarities and differences. Levels of implementation and functional combination differ both among IS (ERP and other IS types), and among industries. But there have been few empirical studies and findings regarding similarities and differences in the implementation and combinatorial pattern of a variety of IS types (ERP and other IS) in factories. Based on this observation, four hypotheses are set. The points of view are both software functionality and industrial difference. Accordingly, a set of empirical studies to investigate the matter was implemented, and this paper reports on the results.
