The constructive step of modelling must account for the specifi c requirements of various stakeholders. Further, the quality of a model in terms of goodnessof-fi t, completeness or other aspects may vary, because of future, as yet unknown, requirements. Natural language underpins the process of modelling as it is the predominant form through which models are acquired, negotiated and agreed. Whilst a model defi nes system requirements, it does not capture the assumptions, discussions and negotiations that led to the requirements. The ability to access this information, which is lost by most development processes, may signifi cantly improve the utility of models with respect to changing requirements and system maintenance. This paper proposes a form of 'literate modelling' that can be used to capture the steps in model development and is based on Toulmin's Argumentation model. The paper contributes the design of an argumentation modelling language and a set of rules for integrating multiple languages (or domains) with the Toulmin approach. The language and approach is applied to the domain of business process modelling.
