This paper describes the thematic development of integrated process understanding, using process modelling and Enterprise Systems, through three consecutive units of an undergraduate degree. It reviews the literature on process modelling and Enterprise Systems, and the pedagogy of their use as teaching tools. It then describes teaching materials and methods designed to ensure that the issues arising from that literature are communicated to students in ways which develop their critical evaluation skills, and their motivation for study. Methods used to ensure that students’ learning is progressively developed from one unit to the next are also described.
