In this paper we analyse the conceptualisation of modelling methods. Thereby we understand, how the components of a specific implementation platform support the design of modelling methods. For this purpose we use the ADOxx meta modelling platform and investigate, how four selected functionalities of enterprise information systems for supporting user interaction, process-based optimization, interfaces to other systems, and complex analyses are realized. We discuss these four functionalities by reverting to excerpts of the visual representation of modelling methods from the areas of requirements engineering, business process management, e-learning, and enterprise architecture management. This permits us to highlight the interdependencies between the modelling language, the modelling procedure, mechanisms and algorithms and the functionalities of the underlying technical platform that have to be taken into account during the conceptualisation.
