The purpose of this study is to investigate the effect of information integration between the production and marketing departments on factory automation performance, and further to identify the contingency variables that influence this relationship. To summarize the research findings: First, it was found that a higher degree of information integration between the production and marketing departments leads to higher factory automation performance. Second, the effect of information integration between production and marketing on factory automation varied according to the degree of market uncertainty and the level of factory automation, confirming that market uncertainty and the level of factory automation are meaningful contingency variables. Third, factory automation performance also varied according to the firm's management orientation. Specifically, marketing-oriented firms devoted greater effort to information integration between production and marketing than firms maintaining a production-oriented management philosophy, and as a result, they achieved more substantial factory automation performance outcomes.
